Delta Dental Offers Alternative Approach to Resolutions

Failure to keep New Year’s resolutions is so commonplace these days that it has become an easy punch line for many derisive jokes. Studies have found only eight percent of people actually keep their resolutions annually. Conversely, one out of four people have never successfully kept a New Year’s resolution.

Maybe the problem is how you think of these resolutions, and simply changing your mindset might help. In 2014, take a cue from the 2007 movie The Bucket List, and put together a list of things that you must do before the year ends.

We at Delta Dental suggest you consider including some oral health-related items in your bucket list. Dr. Bill Kohn, DDS, DDPA’s vice president of dental science and policy, has a few time-honored suggestions:

  • Brush/floss regularly: Commit to brushing your teeth twice a day for two minutes at a time. Simple tools like egg timers or mobile apps can help you keep track of the time. If you never, ever floss, pledge to do so more frequently (starting with once a week and increasing to once a day).
  • Easy on the sweets: Limit your consumption of sugary snacks because the more times teeth are exposed to sugar, the longer acids have time to attack tooth enamel – and expedite tooth decay!
  • Kick butts: Cigarette smoking is the primary cause of severe gum disease in the U.S., so do yourself a favor and quit using tobacco products. Your teeth, gums and lungs will thank you.

Fill your bucket list with things that will make you happy and healthy, provide some adventure, and encourage personal growth. The length of your list doesn’t matter, but you should write it down and refer to it regularly throughout the year. Keep it simple and try to do at least one thing on your list each month.

An appointment with your dentist should be at the top of any healthy checklist. Like most things that we value and want to keep working properly, a regular dental check-up and some preventive maintenance goes a long way towards maintaining long-term, disease-free oral health.

Delta Dental sends you our best wishes for a happy, healthy and prosperous 2014!

Kids Need to Brush Longer and More Often

Poor and infrequent brushing may be major obstacles keeping children from having excellent oral health and are the areas that cause caregivers the greatest concern.

A survey1 of American children’s oral health found that while nearly two out of five Americans (37 percent) report that their child’s overall oral health is excellent, more than a third of the survey respondents (35 percent) admit their child brushes his or her teeth less than twice a day. Parents and caregivers recognize the frequency as “not enough,” despite the fact that nearly all of those surveyed (96 percent) with children up to age 6 say they supervise or assist with brushing.

Among those who rate their child’s oral health as less than excellent, only 56 percent say their child brushes his or her teeth for at least two minutes, which is the amount of time dentists typically recommend spending on each brushing.

Getting children to brush regularly, and correctly, can be a real challenge. Here are some easy ideas to encourage brushing:

  • Trade places: Tired of prying your way in whenever it’s time to brush those little teeth? Why not reverse roles and let the child brush your teeth? It’s fun for them and shows them the right way to brush. Just remember, do not share a toothbrush. According to the American Dental Association, sharing a toothbrush may result in an exchange of microorganisms and an increased risk of infections.
  • Take turns: Set a timer and have the child brush his or her teeth for 30 seconds. Then you brush their teeth for 30 seconds. Repeat this at least twice.
  • Call in reinforcements: If children stubbornly neglect to brush or floss, maybe it’s time to change the messenger. Call the dental office before the next checkup and let them know what’s going on. The same motivational message might be heeded if it comes from a third party, especially the dentist.

Going Green with Delta Dental

DD_Logo_pms360_RGB_3inWhen you think of green and Delta Dental, you might think of the green that has long been a featured part of the logo. But on Earth Day, it’s worth pointing out that Delta Dental companies have taken steps to ensure their business initiatives are green as well.

Delta Dental companies are moving their network provider offices from paper claims to electronic submissions, which helps save paper and reimburses their dentists faster. They also encourage their subscribers to go paperless by signing up for electronic dental benefits statements. A few even provide incentives – such as guaranteeing patient eligibility – for the subscribers who choose to perish paper.

Member companies use blog posts and pins on social media sites like Pinterest to share ideas with their environmentally-conscious consumers about reusing old toothbrushes for garden stakes or as cleaning tools, or turning empty tubes of toothpaste into a pencil holder.

Of course, corporations ought to practice what they preach. One Delta Dental company saved almost $60,000 by eliminating disposable paper cups and retrofitting light fixtures at its headquarters as part of its “green program initiative.”1

Like a lot of corporations in the 21st century, Delta Dental is always searching for ways to improve business efficiency and sustainability. We feel that corporate social responsibility these days must include going green.

Don’t Bottle Up the Oral Health Benefits of Fluoridated Water

Nearly 60 percent  of caregivers say they are more likely to give children bottled water than tap water, potentially depriving kids of fluoride that is critical to good oral health. In addition, according to the 2013 Delta Dental Children’s Oral Health Survey,1 more than twice as many caregivers say bottled water is better for children’s oral health than tap water – an opinion at odds with evidence-based dentistry and more than six decades of public health experience.

Fluoride actually helps to repair (remineralize) tooth surfaces that are damaged by the acid produced by certain bacteria in the mouth, which prevents cavities from continuing to form.2 Since U.S. cities began adding fluoride to water supplies more than 65 years ago, tooth decay has decreased dramatically.3 This result led the Centers for Disease Control and Prevention (CDC) to name water fluoridation “one of the 10 great public health achievements of the 20th century.”4

Unfortunately, only 17 percent of parents believe that tap water is better for their children’s oral health than bottled water.1 Some bottled waters do contain fluoride but usually not in the optimal amount.5  Fluoride in the water provides decay-preventive benefits for the teeth of both children and adults, which makes it the most cost-effective way for communities to improve overall oral health.

The key to fluoride’s protective benefit is by having a little fluoride on your teeth throughout the day. Brushing teeth with a fluoride toothpaste at least twice a day, drinking fluoridated water and limiting frequent between-meal snacking on sugary or starchy foods will help keep most children and adults tooth decay-free.

If children don’t drink fluoridated water, Delta Dental offers these ways to get more fluoride into their diet:

  • Fluoridated toothpastes, mouth rinses and/or professionally-applied gels or varnishes. These products can help strengthen teeth by hardening the outer enamel surface. With toothpaste and rinses children tend to swallow much of what they put in their mouth. So fluoride toothpaste use should start about age 2 and fluoride rinses probably not until about ages 6 or 7.
  • Dietary fluoride supplements, such as tablets, drops or lozenges, which are typically available only by prescription and are intended for children typically older than 6 months living in areas without fluoridated water in their community.
  • Bottled water that states on the label that it contains the right amount of fluoride.

As with other vitamins and minerals, it’s important to get enough, but not too much. When young children whose teeth are still developing under their gums (up to about age 9) get too much fluoride, their teeth may erupt with faint white lines or patches called dental fluorosis. The CDC has reported an increase in dental fluorosis over the past couple of decades. Inappropriate swallowing of toothpaste and children living in fluoridated areas that also receive fluoride supplements are believed to play a major role in this increase.

For advice on the proper amount of fluoride specifically recommended for your child, consult with your dentist. The recommendation will depend on your child’s age, how much fluoride naturally occurs in your local water and your child’s risk for tooth decay.

Traits of Toothpaste

Toothpaste – it has been the foundation of the most basic of daily oral health routines dating back to ancient civilizations. But, how many people today actually know what makes up the concoction that we dab on our toothbrushes and scrub all over our teeth every morning and night? You’ll be happy to know that we’ve come a long way since the use of crushed bones and oyster shells, ashes, burnt eggshells and powder of ox hoof.

Toothpastes, also called dentifrices, are pastes, gels or powders that help remove plaque and strengthen tooth enamel. So, what are all of those substances listed on the side of the tube? The paste or gel itself takes its form from abrasives, water, humectants and binders. Other ingredients like detergents or surfactants; preservatives; flavor, color, and sweetening agents; fluoride; calcium phosphate; anti-bacterials; whiteners; and other agents may be added to provide certain properties to each specific toothpaste forumulation. All of these ingredients can be important for not only helping to prevent dental disease but also for giving the toothpaste the taste, appearance and feel in the mouth that makes a person want to brush with it.

Let’s take a closer look at some of the most common ingredients you will find in your toothpaste and why they are there.

Fluoride is the key active ingredient in toothpaste that has been demonstrated in numerous clinical trials to prevent tooth decay. Fluoride affects the bacteria that cause tooth decay, but its primary action is to incorporate into the tooth structure (enamel and dentin) making the tooth more resistant to acid attack by decay-causing bacteria. It actually repairs (remineralizes) the tooth enamel that gets damaged by the acid producing bacteria present in almost everyone’s mouth. Without fluoride in the toothpaste, the cavity-preventing benefit from brushing your teeth is severely limited. Very few people brush thoroughly enough to prevent cavities by brushing alone. Over-the-counter (OTC) toothpaste in the U.S. contains fluoride at approximately 1,100 parts-per-million (ppm). There are several different fluoride formulations and all are effective in helping to prevent tooth decay. Other remineralizing agents such as amorphous calcium phosphate have demonstrated some decay prevention ability and are now being added to some toothpastes.

Mild abrasives remove food debris and stains, as well as the sticky plaque that is always forming on the teeth. The goal is to make them abrasive enough for efficient cleaning, but not so abrasive as to damage the tooth enamel or the softer dentin or cementum that makes up the tooth root surface. Common abrasives you may see on your tube include calcium carbonate, sodium bicarbonate (baking soda), dehydrated silica gels, hydrated aluminum oxides, magnesium carbonate, phosphate salts and silicates.1

Humectants are organic compounds that hold water and help the toothpaste maintain its moisture even when exposed to air. Examples include glycerol, propylene, glycol and sorbitol.1

Binders or thickeners help keep the whole mix together in a nice paste or gel and stabilize this form. They provide the texture and flow to get the toothpaste onto the brush and keep it there. These include natural xanthum gums, seaweed colloids (carrageenan) and synthetic cellulose.1

Flavor, color and sweetening agents make brushing enjoyable by providing visual appeal, pleasing taste and fresher breath. Specific ingredients vary, but common flavorings include spearmint and peppermint, though nowadays there seems to be toothpaste available in flavors for every taste including strawberry, bubblegum, vanilla, green tea, fennel and bacon – even scotch and bourbon. For a sweet taste, artificial sweeteners like saccharin or natural sweeteners like xylitol are added since they do not promote tooth decay.

Antibacterial agents are added to reduce plaque growth, the sticky bacterial-laden film that forms constantly on the teeth and can eventually cause tooth decay and/or gingivitis and more serious gum diseases if not brushed away regularly. Some anti-plaque agents include triclosan and cetylpyridinum chloride.

Detergents in toothpaste create foaming action that helps the toothpaste coat the teeth. The foam helps reduce surface tension on the tooth, and makes cleaning easier and food particles or debris less likely to reattach to the tooth before it can be spit out. They include sodium lauryl (dodecyl) sulfate (SLS) and sodium N-Lauryl sarcosinate. 1 Some toothpaste users have been reported to develop canker sores as a result of an allergic reaction to SLS, but SLS-free toothpastes are available.

Preservatives prevent the growth of microbes in the toothpaste. Methyl paraben and sodium benzoate are also commonly found in food and beverage products.

Whiteners, desensitizers and tartar preventers Other agents appear in toothpastes that make specific claims for whitening (carbamide peroxide or hydrogen peroxide); desensitizing sensitive root surfaces (potassium nitrate, arginine bicarbonate/calcium carbonate complex); and preventing tartar/calculus buildup (tetrapotassium pyrophosphate/tetra and disodium pyrophosphates, sodium hexametaphosphate). Even though some whitening toothpastes contain similar chemicals to those used in dental office bleaching, these toothpaste products work primarily by removing surface stains and don’t typically change the basic tooth shade like bleaching strips or bleaching treatments at a dental office.

For best tooth decay prevention, we recommend brushing with fluoride toothpaste at least twice a day. So, when is the best time to become one with your favorite toothpaste? Preferably right before bed and in the morning, but soon after meals is also very effective.

New Survey: Kids Need Brushing up on Oral Health

Although cavities are nearly 100 percent preventable, more than one out of four American caregivers reported that their children had a cavity filled in the past year. This was among the findings of a new survey1 of nearly 1,000 caregivers released today by Delta Dental in conjunction with National Children’s Dental Health Month. Among children who had a cavity in the past year, 53 percent had two or more cavities.

The 2013 Delta Dental Children’s Oral Health Survey shows that not only are Americans unaware they can pass cavity-causing bacteria to children, but they also need to brush up on some critical children’s dental health habits, including basics such as brushing and flossing.

Parents and caregivers need to teach good oral health habits to children at a young age to help prevent cavities. Baby teeth are very important. They help children chew and speak properly and hold space for permanent teeth. If a child has healthy baby teeth, chances are he or she will have healthy adult teeth.

These are some of the oral health habits that fall short of what’s recommended by dental professionals:

• Survey shows: Seventy-five percent of caregivers say they share utensils such as a spoon, fork, or glass with a child.
• Delta Dental recommends: Parents and caregivers should eliminate saliva-transferring behaviors – such as sharing utensils and toothbrushes and cleaning a pacifier with their mouths – all activities which can pass harmful bacterial to a child.

• Survey shows: Forty-nine percent of Americans with a child four years or younger report that the child sometimes takes a nap or goes to bed with a bottle or sippy cup containing milk or juice.
• Delta Dental recommends: Parents and caregivers should not put a child to bed with a bottle of milk, juice, sweetened water or soft drinks, which can lead to baby bottle decay. Instead, caregivers should fill the bottle with water.

• Survey shows: For children who have visited the dentist, the average age at the first visit was 3 years old.
• Delta Dental recommends: Children should first visit the dentist within six months of getting the first tooth – and no later than the first birthday.

• Survey shows: Only 58 percent of children had their teeth brushed twice a day and 34 percent of children brush for less than two minutes.
• Delta Dental recommends: Children’s teeth should be brushed twice a day for at least two minutes each time. Parents should assist with this task until the kids are about 6 years old.

• Survey shows: Forty-three percent of parents or caregivers report that their children’s teeth are never flossed, and of children whose teeth are flossed, only 23 percent are flossed daily.
• Delta Dental recommends: Once any two teeth are touching, caregivers should floss, or help the child floss, once a day.

1 Morpace Inc. conducted the 2013 Delta Dental Children’s Oral Health Survey. Interviews were conducted nationally via the Internet with 926 primary caregivers of children from birth to age 11. For results based on the total sample of national adults, the margin of error is ±3.2 percentage points at a 95 percent confidence level.

Delta Dental’s Top 5 Oral Health Resolutions for 2013

With a new calendar year on the horizon, many people are engaging in that time-honored American tradition of making resolutions, vowing to improve certain aspects of their lives.

For individuals who aspire to better their oral health in 2013, Delta Dental offers the following suggestions to help make these resolutions work.

• Brush/floss regularly: The uncomplicated daily one-two punch of brushing twice a day with fluoride toothpaste and flossing once is still the foundation for maintaining healthy teeth and gums. The sooner you can brush following a meal, the better. The longer food stays stuck to your teeth, the more acid is produced that erodes tooth enamel.

• Visit a dentist in 2013: Don’t delay making an appointment for a check-up. Dentists do more than just check and clean teeth. They can also check for signs of serious oral health problems like oral cancer and gum disease, answer questions and provide advice for adults and children and alert patients to signs of potential medical conditions.

• Avoid tobacco products: According to the Centers for Disease Control and Prevention (CDC), half of the cases of severe gum disease in U.S. adults can be attributed to cigarette smoking, and the prevalence of gum disease is three times higher among smokers than non-smokers.1 Consuming products like cigarettes, cigars and smokeless tobacco is arguably the single most destructive oral health habit.

• Eat sweets in moderation: It was ancient Greek philosopher Aristotle who advised, “Moderation in all things” and that axiom rings especially true for sweet snacks. Tooth decay occurs when candy, cookies, sodas and other sweets, or simple carbohydrates like those in chips or crackers mix with bacteria in the sticky plaque that constantly forms on teeth to produce acid, which can destroy tooth enamel. Whenever possible, stick to having sweets with dinner and brush afterward if possible. Limit sugary snacks because the more times during the day that your teeth are exposed, the longer the acids attack.

• Wear a mouthguard during contact sports: It’s not just kids who play contact sports these days. Millions of adults participate in competitive sports leagues in which there can be significant risk of contact. Though there is insufficient evidence to suggest mouthguards prevent concussions, they do absorb and distribute the forces that impact the mouth, teeth, face and jaw when an athlete takes a shot to the face. Wearing a mouthguard can prevent chipped, fractured, displaced or dislodged teeth, fractured or displaced jaws, TMJ trauma, and lacerations to the lips and mouth that result from the edges of the teeth.

Vote for Good Oral Hygiene

My fellow citizens: If you are like most Americans, a toothbrush, a tube of toothpaste and a spool of dental floss are long-standing incumbents in your bathroom cabinet.

During Dental Hygiene Month, another candidate, mouthrinse (also known as mouthwash), is vying for a spot beside the aforementioned daily use products. Should you welcome it to this exclusive club?

For its part, mouthrinse has long campaigned on a cosmetic platform of simply reducing or eliminating bad breath and making your mouth feel fresh. The cosmetic mouthrinse caucus has a large and loyal following. People who use it like that it eliminates bad breath, morning mouth and pesky food particles when used after meals, and that it promises to meld easily into your morning or evening routine. These are noble ideals.

More recently, a new ideology, therapeutic mouthrinse, has tried to distance itself from the cosmetic party line. Therapeutic mouthrinse has on its slate active ingredients like fluoride to fight cavities, and anti-microbial agents (such as hydrogen peroxide) to combat plaque, gingivitis and other gum diseases.

Every candidate has its critics, however, and mouthrinse is no different. Some point out that cosmetic mouthwash has too limited an agenda, that it just masks bad breath but doesn’t reduce cavities, gingivitis or plaque. Others have questioned the harmful effects of some mouthrinse products’ high concentration of alcohol content (ranging anywhere from 6.6 percent to 26.9 percent). A small but vocal contingent believes that factor could be a risk for oral cancer, but so far the overall evidence does not support that conclusion.

These criticisms have led mouthwash to position itself as a dental hygiene populist product that can appeal to all people, introducing non-alcoholic varieties to please even the harshest critics. It has also rolled out exciting new flavors (like cinnamon, bubblegum and orange) to appeal to a block of voters who want fresh breath but desire more than just the taste of mint.

“Mouthrinses are not a substitute for brushing or flossing but they might be a useful addition to your daily oral hygiene routine,” said Dr. Bill Kohn, DDS, a mouthrinse campaign expert and Delta Dental’s vice president for dental science and policy. “At a minimum, most mouthrinses will at least provide temporary relief from bad breath. Check with your dentist if you have persistent bad breath or to see if you would benefit from a mouthrinse that has fluoride or anti-bacterial agents to protect against cavities or periodontal diseases.”

Top 10 Fright Night Facts

Did you know Americans consumed 24.7 pounds of candy per capita in 2010?1 That’s a lot of sugar to potentially cause cavities if left on the teeth of boys and ghouls too long. After eating candy, Delta Dental recommends a thorough brushing of teeth (or at least a big drink of water).

Since Halloween is a favorite holiday of many Americans, Delta Dental has compiled a list of the 10 best terrifically terrifying truths:

1. Americans purchase nearly 600 million pounds of candy for Halloween each year.2

2. Major pumpkin-producing states like California, Illinois, New York and Ohio helped America grow 1.1 billion pounds of pumpkins in 2010.3

3. Sixty percent of dentists polled for Delta Dental’s Tricky Treats survey said they give out candy on Halloween. Of the dentists who dispense candy, 79 percent choose chocolate, while just 13 percent hand out varieties like hard candy or lollipops. This confectionary choice is no accident. Chocolate dissolves quickly in the mouth and can be eaten easily, which decreases the amount of time sugar stays in contact with teeth.4

4. Americans spent nearly $6.9 billion on Halloween costumes, decorations and “entertainment”.2

5. About 50 percent of Americans decorated their homes or yards, 44 percent dressed in a costume, 34 percent attended a Halloween party and 23 percent visited a haunted house in 2011.2

6. In 2011, the three most popular costumes worn by children were Harry Potter, princess and Green Lantern. Classic characters like Winnie the Pooh, Elmo and the Smurfs were also among the top 10 favorites. Captain America, Green Lantern and Where’s Waldo were popular costume choices for adults.5

7. Nearly one out of four dentists said they do not hand out anything on Halloween, while five percent attack the holiday head on by handing out toothbrushes.4

8. Not everyone gives out candy on Halloween. Ideas include toothbrushes, pretzels, fruit (such as raisins), modeling clay and books.4

9. An estimated 41 million children between the ages of five and 14 went trick-or-treating across the U. S. in 2010.1

10. Candy corn, a popular treat commonly associated with Halloween, was created in the 1880s and popularized by farmers who appreciated its resemblance to kernels of corn. 6

Top Five Best Oral Health Practices at School

It may seem like a mindless matter, but packing an apple instead of a sugary snack in a child’s lunch this fall can help improve oral health and educational performance. After all, children eat more than 20 percent of their meals at school during the academic year. So Delta Dental, the nation’s largest dental benefits provider, reminds parents to make good decisions when packing a child’s school lunch.

Overconsumption of sugar harms a child’s oral and overall health. Snacks like cookies, candy and chewy fruit snacks mix with bacteria in the sticky plaque that constantly forms on teeth to generate acid, which can wear away enamel and cause tooth decay. While sweets may provide a temporary jolt for kids, that sugar rush soon turns into a crash and kids are left feeling lethargic. That is not the kind of mental state kids need to prepare for an afternoon of classes.

Instead, Delta Dental recommends these top five oral health best practices:

• After breakfast, before leaving for school, make sure your child brushes well with a fluoridated toothpaste. Brushing immediately following a meal helps clean teeth and eliminates halitosis (bad breath).

• Fill a child’s lunch box with healthy lunch food and snacks such as lean meats, whole grain breads, low-fat yogurt or cheeses, apples, bite-size carrots and baked chips or whole-grain crackers. Besides being packed with nutrients, certain fruits and veggies can even help clean the teeth and gums. Make treats a treat. Serve sugary sticky snacks like cookies, cake and brownies and candy only in moderation. Room parents should discuss bringing in healthy snacks along with sugary treats for birthdays and other classroom parties.

• If a child chews gum and the school allows it, chewing sugar-free gum for a few minutes in between lunch and afternoon classes can help stimulate saliva to buffer the acid and help dislodge food particles from the mouth. Gum containing the natural sweetener, Xylitol, is a particularly good option since studies have shown that consistent exposure to Xylitol can reduce cavity-causing bacteria in the mouth.

• Children with braces should try to brush or rinse well with water after lunch. Children who wear removable retainers should clean them well after each meal and rinse out their mouths.

• Before the school year starts, schedule a dental visit to make sure there are no problems to distract a child during the school year. Ask the dentist about sealants as a way to protect children’s teeth from cavities. Sealants – a thin coating of bonding material applied over the chewing surface of molar teeth – act as a barrier to cavity-causing bacteria.
