Since the teeth in the back of the mouth are mostly used for chewing, have uneven surfaces and are more difficult to clean properly, they are more prone to dental decay. Dental sealants are a clear plastic material that can be used to cover the crevices and grooves of a healthy tooth and protect it from decay.
Sealants were originally used to treat children, but more and more adults are advised to get them. Applying sealants is easy, painless and quick. However, it necessary to ensure that no saliva or bacteria gets under the sealant or else it might not stick correctly. The dentist has to make sure that the surface of the tooth that is being sealed is completely dry. Sealants are applied as a fluid and become solid in a matter of seconds. They can last up to 15 years, but the dentist can check the condition of the sealants during a regular visit and see if any of them need replacing.
Sealants are an effective way to prevent decay, but this does not mean that the patient should stop looking after the teeth. It is still necessary to maintain proper dental hygiene, including brushing, flossing, using enough fluoride and visiting the dentist for regular checkups.
