Dental Sealants

Dental sealants are liquid resins that bond and harden in the deep grooves on the biting surfaces of back teeth (molars and premolars). They keep food and bacteria from getting trapped, which can prevent decay.


The procedure is quick and painless. It starts with thoroughly cleaning and drying the tooth surface, then applying an acid gel to “roughen up” the enamel to help the sealant adhere.

Prevents Tooth Decay

Even if you brush and floss regularly, it’s hard to clean the small cracks and grooves on your back teeth. These tiny areas, called fissures, can trap food and bacteria that lead to tooth decay. Dental sealants fill in these grooves, creating a smooth surface that’s easier to clean.

Typically, we recommend sealants for children to protect their teeth as they grow in and mature, but adults can also get them. It’s best to seal molars and premolars as soon as they erupt, usually in childhood or early adulthood. That’s when the teeth are most likely to develop cavities.

With sealants, we paint a clear or tooth-colored coating onto the chewing surfaces of the molars and premolars. Then we harden the sealant with a special curing light. The tooth-colored sealant blends in with the natural enamel, creating a thin, protective barrier against plaque, food debris and bacteria that can cause cavities.

Before applying the sealant, we will thoroughly clean and dry your tooth. We may also apply an acid etching solution to the tooth’s chewing surfaces to roughen them up, which helps the sealant bond properly. Then we wash off the etching solution and dry your tooth again. We paint the sealant on the tooth enamel and harden it with the curing light. The procedure is painless and no longer takes more than a minute or two.

Prevents Cavities

Sealants act as an extra protective layer to stop food particles and bacteria from settling in the deep grooves of your molars. They’re an excellent complement to brushing, flossing and regular dental cleanings. In fact, studies have shown that children with sealants on their permanent molars have three times fewer cavities than children without them.

The process of applying dental sealants is quick and pain-free. First, your dentist cleans and dries the tooth before applying an acidic gel to roughen up the enamel surface. This helps the sealant bond with the tooth. After that, your dentist rinses off the gel and applies the liquid sealant to the grooves of the teeth. Then a special curing light hardens the sealant.

Most children need their molars sealed after their first come in at around age 6 and before their second molars break through at about age 12. However, adults with healthy molars may benefit from them as well.

Dental sealants are long-lasting, but they do need to be checked and reapplied regularly. Some foods like chewing ice or sticky candy can dislodge the sealant, so it’s important to talk to your dentist Modern Essence Dentistry about any concerns you have about sealants. Your dentist will evaluate the condition of your sealants and determine if they need to be replaced.

Prevents Wear

Sealants act as a protective barrier against the daily grind of chewing. As such, they are a great way to protect your child’s molars from bacteria and decay in those tight nooks and crannies that are so difficult to clean with brushing alone. They are quick and easy to apply, and last for several years with proper care.

Before applying the sealant, we thoroughly clean each tooth, removing any plaque or debris from the surface. Next, the chewing surfaces are isolated using cotton rolls or a special isolating material to keep the teeth dry for better adhesion. Sometimes, an etching gel is put on the chewing surface to roughen up the enamel slightly for better bonding. Once this is done, the tooth is rinsed and dried and then ready for the sealant.

Usually a safe plastic resin, the sealant is painted on and then hardened with a curing light. Once done, the teeth are instantly protected from food particles and bacteria.

Dental sealants are a safe, quick and painless procedure to protect children’s teeth from cavities and decay. As with any preventive measure, they are not a substitute for brushing, flossing and regular dental check-ups. But they are an excellent supplement to help combat the most common causes of tooth loss in kids: molar and premolar decay.

Prevents Damage

Many dentists recommend dental sealants as a preventive treatment for children’s teeth, although it is safe to use on adults as well. They are typically applied to the back teeth (molars and premolars) to help protect them from decay. These teeth are responsible for chewing and grinding food, but they also have deep pits and fissures that can be difficult to clean. Food gets trapped in these grooves, and if it is not removed, it can cause plaque which can eventually lead to cavities.

By applying a sealant to the tooth, these grooves are filled in and can no longer harbor plaque. Additionally, the sealant creates a barrier between the tooth and food, which can make it harder for bacteria to reach the enamel and start a cavity.

Unlike fillings, which require injections and a drill, dental sealants are painless and quick to apply. During the procedure, a mild “etching” solution will be applied to the chewing surfaces of the teeth to roughen them up and help the sealant bond with the tooth. Then, the teeth are washed and dried, and the sealant is painted onto the chewing surface of the teeth and into the grooves and fissures. Some sealants dry on their own, while others are cured with a curing light.

The sealants will last for up to ten years, but regular checkups are essential so that the dentist can look for any signs of wear and tear or chipping and replace the sealant as needed. Patients may occasionally feel a bit of sensitivity after the sealant is applied, but this is usually short-lived and rinses away easily.
