Dental Sealants for Cavity Protection

What Are Dental Sealants?

Dental sealants are thin, liquid coatings painted onto the chewing surfaces of your back teeth (molars and premolars). Once applied, a dentist cures and hardens the sealant to shield your teeth from cavity-causing bacteria.

Why Are They Important?

Your molars have deep grooves that trap food and bacteria, making them prone to decay. Sealants coat these areas, preventing harmful particles from settling in and causing cavities. They’re like raincoats for your teeth!

Who Should Get Sealants?

Children and teenagers benefit most from sealants, especially between ages 6 to 14. Adults with healthy molars and no fillings may also be good candidates. Even baby teeth with deep grooves may be protected with sealants in some cases.

Materials Used

Sealants are typically made from medical-grade resins (plant or synthetic) or glass ionomers (a mix of glass powder and acid). Both materials are safe and effective in preventing decay.

How Are Sealants Applied?

The application is simple and painless:

• Teeth are cleaned and dried.
• A mild acid solution is applied to roughen the surface.
• Sealant is painted onto the grooves.
• A curing light hardens the material.

Benefits and Longevity

Sealants protect hard-to-clean areas of the teeth, reducing the risk of cavities. They typically last up to five years and may need occasional replacement. They’re less expensive than fillings and help avoid more invasive treatments later.

Aftercare and Follow-Up

There’s no downtime after sealant application—you can eat and drink right away. Avoid extremely hard or sticky foods to help your sealants last longer. Continue regular dental visits every six months for checkups and maintenance.

Are They Necessary?

Sealants are highly recommended for cavity prevention, especially in children. Kids without sealants are three times more likely to develop tooth decay. However, they’re not suitable for teeth with fillings, crowns, or incomplete eruption. Ask your dentist if sealants are right for you or your child.
