Sealants

Dental Sealants - Seal Out Tooth Decay

What is a sealant?

A sealant is a clear or shaded plastic material that is applied to the chewing surfaces of back teeth. This is where decay most often occurs.

(See more information below.)

What does a sealant do?

A sealant prevents tooth decay. It covers the pits and grooves of chewing surfaces and seals out decay-causing food and germs.

When should sealants be placed?

Sealants are most beneficial if they are placed on permanent molars as soon as the teeth come in.

The first permanent molars grow in between the ages of 5 and 7. The second permanent molars grow in between the ages of 11 and 14.

How is a sealant placed?

A sealant is placed by a dental professional. The procedure is simple and painless. It takes only a few minutes. The tooth is cleaned and treated with a solution that allows the sealant to stick to the tooth. Sealants are painted on as a liquid and quickly harden to form a shield over the tooth.

How long will a sealant last?

Sealants can last for up to 10 years. They can be checked at dental visits to see if they need to be replaced.

What about fluoride?

Fluoride makes teeth more resistant to decay and can repair tiny areas of decay before they become big cavities. The most common sources of fluoride are toothpaste or fluoridated water. Both sealants and fluoride are recommended for best protection against tooth decay.

Sealants + Flouride = Maximum Protection Against Cavities

A Message from Your Dental Health Coordinator

Children need to have their teeth and gums cleaned daily to prevent tooth decay and gum disease. Parents need to help children learn oral hygiene skills.

Brushing Basics

A parent should supervise brushing for children under age 8.
Brush twice a day - in the morning and at bedtime.
A thorough brushing takes 2-3 minutes.
Use a soft bristled toothbrush.
Use a smear or pea-size portion of fluoride toothpaste. Fluoride toothpaste is not recommended for children under 3.
Children should spit out toothpaste. Swallowing toothpaste should be discouraged.
Replace toothbrushes every three months. If your child has just recovered from an illness, use a new toothbrush.

Flossing Facts

Flossing helps to prevent gum disease.
Flossing cleans between teeth and under the gums where the toothbrush cannot reach.
A parent will need to floss their child's teeth until around age 9. Usually by this time the child should be able to floss on his/her own.

Beat Sweets

Encourage healthy snacks.
Reduce how often snacks are offered, especially sticky foods that cling to teeth.
Eat sweets at the end of a meal. Increased saliva flow during meals helps reduce the effects of harmful acids.
