Dental Sealants: Their Role In Preventing Tooth Decay

Table of Contents

Dental sealants are a thin layer of filling placed inside the deep grooves and pits on the chewing surfaces of teeth.

Dental Sealants

Sealants are placed in molars and premolars, which are most prone to cavities. Sealants function as a barrier, preventing food particles, plaque, and bacteria from the deep grooves and lines of teeth, which can be difficult to clean with just brushing.

They are especially beneficial in kids and adults at a high risk of developing caries.

How do dental sealants work?

Sealants are placed inside the deep grooves and pits on the chewing surfaces of molars and premolars.

Applying sealants is an easy process. Teeth are cleaned and dried, followed by applying a liquid adhesive, which is then hardened using a special curing light.

Once it sets, it acts as a barrier against food particles, plaque, and bacteria getting stuck in the deep grooves and lines of teeth 

Benefits of dental sealants

The sealants decrease the risks of cavities by blocking the areas on teeth, that are more prone to develop decay. It’s especially beneficial in children and adults who have poor oral hygiene or who are at a high risk of caries.

This proactive measure helps to prevent further pain and costs related to fillings and hence retains natural teeth supporting sustainability in dental care.

The importance of Dental Sealants in children

Young teeth are more prone to cavities due to their developing enamel and the challenges of maintaining proper oral hygiene.

Dental sealants are a safe and effective solution for preventing cavities in children and promoting long-term oral health.

Deep pits and fissures in permanent molars and premolars, improper brushing, and frequent intake of sugary snacks and drinks are some of the main reasons that make children more prone to cavities.

Role of dental sealants in preventing cavities

Dental sealants afford a protective layer to the teeth in areas more susceptible to developing cavities. They create a protective barrier over these areas, reducing the likelihood of dental decay.

When Should Children Get Dental Sealants?

Research shows that flossing, brushing with fluoride toothpaste and application of dental sealants can effectively prevent children from getting cavities.

Sealants can significantly lower the decay rate of permanent dentition in the initial two years after application and it has a protective effect for several years. It is a preventive dental procedure that is effective for both kids and adults. 

When Should Children Get Dental Sealants?

The recommended age for dental sealants for children is between 6 -12 years, after the eruption of permanent molars and premolars.

Sealants should be placed as early childhood oral preventive measures, thus laying a foundation in children for proper dental and gum care throughout their lifetime.

Who’s a candidate for getting dental sealants?

Children and adults with teeth having deep grooves and fissures
