Sealants Critical to Children’s Oral Health

Sealants are plastic coatings that protect those difficult to reach pits and grooves on the chewing surfaces of the teeth from the bacteria that cause tooth decay. A quick and painless procedure done in your dentist’s office, sealants are applied to the chewing surfaces of permanent molars as soon as possible after they fully erupt in the mouth, usually between the ages of six to eight for first molars and 10 to 12 for second molars. While sealants are not necessary for all children, they are particularly beneficial to children who are at higher risk for tooth decay. But, how do you know if your child is at higher risk?Although overall oral health risk is a combination of genetics, personal habits and diet, history of decay is a good predictor for future risk of decay. Your child is considered to be at higher risk if he or she has had a cavity filled in the past three years. The good news is you may be able to help prevent future cavities by making sure your child receives preventive care, including having sealants applied to first and second molars.

Although approximately 60 to 70 percent of cavities can be prevented by placing
sealants on children’s teeth, a recent study by Delta Dental shows that 60 percent of
children age 6 to 9 who are at higher risk of tooth decay did not receive sealants on
their first molars, and 80 percent of children age 11 to 15 did not receive sealants on
their second molars.1

These figures are particularly striking when you realize that many dental plans cover preventive care, like sealants, at as much at 100 percent of the cost. As a parent, you want your child to be as healthy as possible, and that includes protecting their teeth. Delta Dental is here to help. Our myDentalScore risk assessment tool helps you better assess your child’s risk for oral disease by providing an easy to understand oral health scores report that you can use to consult with your dentist to determine the best treatment patterns for your child’s oral health needs. We also encourage you to take a look at your dental plan and make sure you are using preventive treatments to their full advantage – most are simple, painless and inexpensive. They can save your child from future pain and discomfort that often accompany cavities, and save you from paying for expensive fillings, crowns, or root canals.

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.

Sealing a Smile Packs a Preventive Punch

Why is 80 percent of tooth decay found in only 25 percent of children, disproportionately kids from low-income families?1 The answer is multifold and complex, but Delta Dental believes that school-based dental sealant programs are a large part of a workable solution.

Dental sealants are a critical but underutilized component of preventive dentistry. The one-two punch of sealants and fluoride (in toothpaste and water) along with a proper diet can almost totally prevent new tooth decay.

National surveys by the Centers for Disease Control and Prevention (CDC) indicate that only 38 percent of children and teenagers ages 12 to 19 have dental sealants. This number is much lower among children from low-income families and certain races/ethnicities with higher tooth decay rates who would benefit most from sealants.1

Dental sealants can save families time, money and the discomfort of dental fillings. Sealants are thin, plastic coatings applied to the pits and grooves of teeth to protect them from the bacteria and foods that lead to tooth decay. First and second permanent molars are the most likely to benefit from sealants, so it’s best if the sealant is applied soon after those teeth appear, before they have a chance to decay (usually ages 6 and 12).

A sealant is virtually 100 percent effective if fully retained on the tooth, and studies have shown they remain intact 92 to 96 percent of the time after one year and 67 to 82 percent after five years. Sealants should be checked at each regular dental appointment and can be reapplied if they are no longer in place. 2

Sealants delivered through school-based programs have been shown to decrease tooth decay by 60 to 65 percent.3 Using school-based sealant programs at lower-income schools has proven to be highly effective in improving the oral health of those schoolchildren. Studies of children in either Medicaid programs or with private dental insurance show that placement of sealants on first and second permanent molars reduced the need for future cavity fillings.
