Dental sealants are an easy way to help prevent tooth decay before it even occurs. These safe plastic resin coatings are applied to the grooves that are usually found on the chewing surfaces in the back teeth to protect teeth from damage caused by accumulation of plaque, and food. Sealants are painted on as a liquid and quickly harden to form a shield within the grooves over the tooth. Sealants work by filling in the crevasses on the chewing surfaces of the teeth. This eliminates the reason why food particles get caught in the teeth, preventing cavities.
The application is fast and comfortable and can effectively protect teeth for many years.
Many people think sealants are only for children and adolescents, but adults can also benefit from sealant treatment. Sealant application is quick and convenient, and the benefits last for several years.
How are sealants put on?
- The tooth is cleaned.
- The tooth is dried, and cotton is put around the tooth so it stays dry.
- 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.)
- The tooth is rinsed and dried. Then new cotton is put around the tooth so it stays dry.
- The sealant is applied in liquid form and hardens in a few seconds.
- The sealant is in place.
Why get sealants?
The most important reason for getting 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.
Sealants cover the chewing surfaces of the back teeth and keep out germs and food.
Having 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 always the best tooth. That's why sealants are so important to prevent decay.
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 sealants?
Children should get sealants on their permanent molars as soon as the teeth come in -- before decay attacks the teeth.
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 between 11 and 14 years old.
The premolars come in between the ages of 8 and 10.
All teeth with pits and grooves also might need to be sealed. Teenagers and young adults who are prone to decay may also need sealants.
Should 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 sealants?
Some health insurance programs pay for sealants.
We at Gainesville Dental Arts will contact your insurance company for details.
How long do sealants last?
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 sealants by adding more sealant material.
Are sealants new?
No, 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 sealants.
In fact, less than one-third of children in the United States have sealants on their teeth.
Besides sealants, are there other ways to prevent tooth decay?
Yes. Using fluoride toothpaste and drinking fluoridated water can help protect teeth from decay. Fluoride can be prescribed in the form of a
gel, mouth rinse, or tablet.
Fluoride is the best defense against tooth decay! Fluoride...
- 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 decay
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 decay.
Sealants and fluoride together can prevent almost all tooth decay.
