A sealant is a thin layer of plastic that is applied to the chewing surfaces of molars, premolars, and deep grooves (known as pits and fissures) on teeth. These deep grooves are where more than 75% of dental decay typically starts. Due to their anatomy, these teeth are difficult to clean properly and are highly vulnerable to decay. By applying a sealant, the tooth's deep grooves are sealed off, creating a smooth surface that is easier to clean.

Sealants provide long-lasting protection against tooth decay, but it is important to have them checked for wear and chipping during regular dental visits. Monitoring their condition ensures that they continue to effectively safeguard the teeth.

Reasons for sealants:

• Children and teenagers – As soon as the six-year molars (the first permanent back teeth) appear or any time throughout the cavity prone years of 6-16.

• Adults – Tooth surfaces without decay that have deep grooves or depressions.

• Baby teeth – Occasionally done if teeth have deep grooves or depressions and child is cavity prone.

What do sealants involve?

Applying sealants is a quick and straightforward procedure performed by your dentist or dental hygienist. Each tooth that requires sealing is first cleaned thoroughly, and a cotton barrier is placed around it to maintain dryness. A special solution is then applied to the enamel surface, aiding in the bonding of the sealant. After rinsing and drying the teeth, the sealant material is carefully painted onto the deep grooves or depressions of the enamel. Depending on the type of sealant used, it will either harden on its own or with the use of a curing light.

To ensure the longevity of your sealants, it is important to practice good oral hygiene at home, maintain a balanced diet, and keep up with regular dental visits. These measures will help extend the effectiveness and lifespan of your newly applied sealants.
