SEALANTS 

Introduction:

A sealant is a clear or white material that is applied to the chewing surfaces of the back teeth — the molars and premolars. Sealants protect these teeth from cavities by filling in the grooves on the chewing surfaces that are too deep for a toothbrush to clean.

Sealants are usually made of a plastic material and are applied to the teeth in a liquid form. Once they harden, they provide a physical barrier that prevents food and bacteria from getting into the grooves of the teeth and causing cavities. Sealants can last for several years, but they will need to be checked and replaced if they become worn or damaged.

Types of Sealants:

There are two main types of sealants: resin-based and glass ionomer.

1. Resin-Based Sealants are made of a plastic material that is applied to the teeth in a liquid form and then hardened with a light. Resin-based sealants can last for several years, but they will need to be checked and replaced if they become worn or damaged.

2. Glass Ionomer Sealants are made of a glass material that is applied to the teeth in a liquid form and then hardened with a light. Glass ionomer sealants can last for several years, but they may need to be checked and replaced more often than resin-based sealants.

How are Sealants applied?

Sealants are usually applied in a single visit to the dentist. The tooth will be cleaned and dried, and then the sealant material will be applied in a liquid form. Once the sealant material hardens, it will provide a physical barrier that prevents food and bacteria from getting into the grooves of the tooth and causing cavities.

After the sealant is applied, you or your child can resume normal activities immediately. There is no need to wait for the sealant to harden before eating or drinking.

How long do Sealants last?

Sealants can last for several years, but they will need to be checked and replaced if they become worn or damaged. Your dentist will check the sealants at your regular dental visits and can replace them if necessary.

Uses of Sealants:

Sealants are usually used on the permanent molars and premolars of children. The American Dental Association (ADA) recommends that sealants be placed on the permanent molars of children as soon as they come in — usually around age 6 or 7. The ADA also recommends that sealants be placed on the permanent premolars — the teeth next to the molars — as soon as they come in, usually around age 11 or 12.

Sealants can also be placed on the primary (baby) teeth of children who are at high risk for cavities, such as those with a family history of cavities or those who have had cavities in the past. Sealants are not a substitute for good oral hygiene, however. They should be used in addition to regular brushing and flossing.

Conclusion:

Sealants are a great way to help prevent cavities in both children and adults. If you are considering sealants for yourself or your child, talk to your dentist to see if they are right for you. Sealants can last for several years, but they will need to be checked and replaced if they become worn or damaged. Regular dental visits are the best way to ensure that your sealants are in good condition.
