Dental Sealants

Protective coatings applied to the chewing surfaces of the back teeth to prevent cavities.

Daily tooth brushing is essential, but it alone won’t be enough to keep cavities away. A toothbrush remains the number one tool in keeping teeth clean. But it cannot reach all tooth surfaces.

The Molars or back teeth used for heavy chewing are vulnerable to decay and cavities. They have grooves that toothbrush fibres cannot penetrate. If debris is stuck, it can turn into plaque, tartar and even lead to cavities.

But you can protect your teeth with the help of dental sealants.

What are dental sealants?

Dental sealants are thin, plastic coatings applied on tooth surfaces. They serve as a layer of protection by keeping debris out of the teeth.

Debris can get stuck on fissures and tight spaces between teeth. They can be hard to remove, and if they stick around, they become food for harmful bacteria.

They then turn into acids and break down the enamel. This leads to holes in the teeth or cavities that can be excruciating and unsightly.

Who needs dental sealants?

Children and teenagers are ideal candidates for dental sealants. Their vulnerable molars need protection against decay and cavities.

Baby teeth can also benefit from sealants in keeping debris out. The sooner these teeth are protected against potential damage, the easier it is to keep smiles cavity-free.

Adults can also receive sealants, especially if their molars are without fillings or showing signs of decay.

How are dental sealants applied?

Applying dental sealants is a quick process. Here are the steps involved in the procedure:

Your dentist reviews your medical and oral health history to determine if sealants are for you.

The next step is tooth preparation, where the tooth is cleaned, and debris is removed from tooth fissures.

Afterward, the tooth is dried and isolated to keep saliva from filling its grooves.

The surface is roughened to establish a stronghold for the sealant.

The sealant is applied and hardened using a special light.

Your dentist checks if there are changes in your bite after sealant application.

Sealants are temporary, but they can last for 10 years with good dental care. They will need touch-ups once they wear or chip.

During routine dental checkups, your dentist lets you know if your sealants already need fixing.
