Definition

A dental sealant is a thin, plastic coating applied to the chewing surfaces of molars and premolars to prevent cavities. Sealants act as a barrier, sealing off the grooves and pits of the teeth, making them smoother and easier to clean.  By applying sealants, dental professionals aim to reduce the risk of cavities and maintain optimal oral health for their patients, especially in areas prone to decay.

How to Fix It

Sealants are commonly used in children and teenagers to protect their teeth from decay in hard-to-reach areas where food particles and bacteria can easily accumulate. When a tooth exhibits signs of minor decay or shows deep fissures and grooves that are susceptible to future decay, a dental sealant may be recommended as a preventative measure.

 

The process of applying a sealant is straightforward and painless, typically involving the cleaning of the tooth surface, followed by the application of an acidic gel to roughen the enamel. This etching step ensures that the sealant bonds effectively. After rinsing off the gel, the tooth is dried, and the sealant is painted onto the enamel where it hardens, often with the aid of a curing light.

Related Facts

Dental Sealants are used in both pediatric and adult dentistry. For younger patients sealants are particularly beneficial for molars and premolars due to their effectiveness in shielding the enamel from plaque and acids, thereby preventing cavities and minimizing the need for more invasive dental procedures in the future.

Sealants are also used in adults who are susceptible to decay or with early signs of tooth decay to provide a protective barrier, especially for molars and premolars with deep grooves that are difficult to clean.

Dental sealants can last several years under the force of normal chewing and can be reapplied if necessary. They are clear or tinted to blend with the natural color of teeth, making them virtually invisible.
