1. What is dental sealant?

Preventing dental issues is always best. One preventive strategy is dental sealant. What is it?

A thin, plastic coating is put on the chewing surfaces of back teeth (molars and premolars). Deep grooves and pits make these surfaces teeth decay-prone. The sealant protects these sensitive locations from microorganisms and food particles.

Dental sealant application is rapid and painless. Teeth are cleansed and dried first. Applying an acidic solution to the tooth surface helps the sealant attach. A unique curing light may speed up hardening for some dentists.

2. Why dental sealant is needed?

If you have decent oral hygiene, you may ask why dental sealant is needed. Regular brushing and flossing are essential for dental health but may not reach the deep valleys and pits of the back teeth. These regions become bacteria breeding grounds and deteriorate. The sealants protect hard-to-reach places from cavities.

Since children and teens are more prone to tooth decay, the sealants are often suggested. Sealants can also help adults with deep back tooth grooves and pits. The technique is safe for children and adults and can be done by a dentist or hygienist during a routine visit.

3. How long does dental sealant last?

Dental sealants typically last five to 10 years. Sealants can last longer with proper oral hygiene, including brushing and flossing. Sealants wear out over time and may need to be replenished.

Certain habits and actions can harm sealants. Sealants can chip or crack when biting on ice or opening packaging with teeth. Chewing sticky candy or drinking acidic drinks might degrade sealants.

Maintaining the sealants requires regular dental exams. Dentists and hygienists check sealants during routine exams and recommend repairs or replacements. They will also assess the patient’s dental hygiene to guarantee the optimum outcome.
