Dental Sealants are thin, plastic coatings painted on
the chewing surfaces of the back teeth.
Dental Sealants are put on in dentists' offices,
clinics, and sometimes in schools. Getting Dental Sealants put on is simple and
painless. Dental Sealants are painted on as a liquid and quickly harden to form a
shield over the tooth.
How are Dental Sealants put on?
1. The tooth is cleaned.
2. The tooth is dried, and cotton is put
around the tooth so it stays dry.
3. A solution is put on the tooth that makes
the surface a little rough. (It is easier for the sealant to stick
to a slightly rough surface.)
4. The tooth is rinsed and dried. Then new
cotton is put around the tooth so it stays dry.
5. The sealant is applied in liquid form and
hardens in a few seconds.
6. The sealant is in place.
Why get Dental Sealants?
The most important reason for getting Dental Sealants
is to avoid tooth decay.
Fluoride in toothpaste and in drinking water
protects the smooth surfaces of teeth but back teeth need extra protection.
Dental Sealants cover the chewing surfaces of the back teeth and keep out germs and
Having Dental Sealants put on teeth before they decay
will also save time and money in the long run by avoiding fillings, crowns,
or caps used to fix decayed teeth.
What causes tooth decay?
Germs in the mouth use the sugar in food to
make acids. Over time, the acids can make a cavity in the tooth.
Of course a healthy tooth is the best tooth. So
it is important to prevent decay. That's why Dental Sealants are so important.
Why do back teeth decay so easily?
The chewing surfaces of back teeth are rough
and uneven because they have small pits and grooves. Food and germs can get
stuck in the pits and grooves and stay there a long time because toothbrush
bristles cannot brush them away.
Who should get Dental Sealants?
Children should get Dental Sealants on their permanent
molars as soon as the teeth come in -- before decay attacks the
The first permanent molars -- called "6 year
molars" -- come in between the ages of 5 and 7.
The second permanent molars -- "12 year molars"
-- come in when a child is between 11 and 14 years old.
Other teeth with pits and grooves also might
need to be sealed.
Teenagers and young adults who are prone to
decay may also need Dental Sealants.
Should Dental Sealants be put on baby teeth?
Your dentist might think it is a good idea,
especially if your child's baby teeth have deep pits and grooves.
Baby teeth save space for permanent teeth. It
is important to keep baby teeth healthy so they don't fall out early.
Does insurance pay for Dental Sealants?
Some health insurance programs pay for
Dental Sealants. Check with your state Medicaid program or your insurance company
How long do Dental Sealants last?
Dental Sealants can last up to 10 years. But they need
to be checked at regular dental check-ups to make sure they are not chipped
or worn away. The dentist or dental hygienist can repair Dental Sealants by adding
more sealant material.
What if a small cavity is accidentally covered by a sealant?
The decay will not spread, because it is sealed
off from its food and germ supply.
Are Dental Sealants new?
No, Dental Sealants have been around since the 1960s.
Studies by the National Institute of Dental and Craniofacial Research and
others led to the development of Dental Sealants and showed that they are
safe and effective.
But many people still do not know about
Dental Sealants. About one-third of children in the United States have Dental Sealants on
Besides Dental Sealants, are there other ways to prevent tooth decay?
Yes. Using fluoride toothpaste and drinking
fluoridated water can help protect teeth from decay.
Water is fluoridated in about two-thirds of
cities and towns in the United States. If your water is not fluoridated or
if your children's teeth need more fluoride to stay healthy, a dentist can
prescribe it in the form of a gel, mouthrinse, or tablet.
Fluoride is the best defense against tooth
makes teeth more resistant to decay
repairs tiny areas of decay before they
become big cavities
makes germs in the mouth less able to cause
Fluoride helps the smooth surfaces of the teeth
the most. It is less effective on the chewing surfaces of the back teeth.
Regular brushing -- with fluoride toothpaste -- also helps prevent tooth
Dental Sealants and fluoride together can prevent
almost all tooth decay.
How can I get Dental Sealants for my children?
Talk to your dentist, state or local dental
society, or health department. Sometimes Dental Sealants are put on at school.
Check with your school about whether it has a sealant program.
