What Are Sealants And Why Are They Necessary?

Posted on 8/21/2023 by Joseph Kabaklian DDS
What Are Sealants And Why Are They Necessary?Dental sealants are thin coatings applied to the back teeth's chewing surfaces. They form a protective barrier on the molars and premolars. They aim to avoid dental caries and acid attacks on the tooth enamel. The sealant forms a protective shell around the tooth, shielding the enamel and reducing the risk of cavities. The following are the benefits of sealants:

Prevent Tooth Decay

Sealants provide adequate protection against cavities by covering the tops of molars with a tooth-colored plastic coating. This extra layer acts as a barrier, making it challenging for bacteria to adhere to the tooth's surface. As a result, the risk of cavities is significantly reduced, promoting better oral health.

Decrease Deep Grooves

Molars have intricate grooves on their chewing surfaces, which can be difficult to clean thoroughly with a toothbrush. These deep areas are prone to plaque and food particle accumulation. They create an ideal environment for bacteria to thrive. Over time, this buildup can lead to tooth decay. Dental sealants provide a protective barrier, filling in the deep grooves and preventing decay from developing in these vulnerable areas.

Suitable For All Ages

Although sealants are commonly applied to children's teeth, individuals of all ages can benefit from them. Even permanent teeth of older patients have tiny grooves and pits that require protection against bacteria. Sealants cover these vulnerable areas, providing an extra barrier against decay-causing bacteria, regardless of age.


Applying sealants during childhood offers long-lasting protection during the most cavity-prone years. With proper care, sealants can last for many years. But maintaining good oral hygiene and avoiding biting hard objects can further extend their lifespan. During regular dental check-ups, our dentist will assess the condition of the sealants and may recommend re-application or repair if needed. This ensures continued effectiveness in preventing cavities.
