Dental sealants are a preventive treatment that helps protect your teeth from cavities. They’re a thin, flowable composite coating applied to the chewing surfaces of your back teeth (molars and premolars), where cavities are most likely to form. These surfaces have tiny grooves and pits that can be hard to clean, and that’s where plaque and bacteria can build up and start causing decay.
The sealant works by filling in those grooves, creating a smooth surface that makes it easier to keep the tooth clean and less likely to get cavities. It’s a simple, painless process that can be easily done without the need for dental anesthetic. The sealant is painted onto the tooth, and a special light hardens it. It typically lasts several years and can be reapplied if needed.
Sealants are especially helpful for children and teenagers, but adults can benefit from them too, especially if they have deep grooves in their teeth. They’re a great way to prevent problems before they start. These can even be applied by your hygienist during your routine dental cleaning visit.
