Dental Sealants

Dental sealants are like raincoats for teeth, protecting them from decay-causing bacteria. Both children and adults can benefit from this preventive treatment, but the earlier a tooth is sealed, the better.


First, the dentist cleans the chewing surface of each tooth. They then isolate each tooth with cotton or another absorbent material. A thick liquid called etch is then painted onto the tooth’s chewing surfaces, roughening it up to help the sealant bond.

Prevents Cavities

Dental sealants help prevent cavities by filling in the tiny grooves and pits on chewing surfaces, especially molars in the back. These nooks and crannies are difficult for toothbrush bristles to clean, so food debris and bacteria get stuck and can cause decay. The best time to apply sealants is after a tooth has had a cavity filled or treated, but it’s also important to brush and floss regularly to keep plaque at bay.

The process of applying sealants is quick, painless and relatively inexpensive compared to other dental treatments. First, a dentist will thoroughly clean and dry the tooth or teeth before applying a thin coat of an acidic gel that roughens up the surface of the tooth, allowing the sealant to bond more effectively. The tooth is then rinsed off and dried again. Finally, the liquid sealant is applied to the tooth and hardened with a special light.

Dental sealants are a great way to prevent cavities in children’s permanent teeth. A cavity-free tooth is healthier and stronger than a damaged or untreated one, and it sets kids up for healthy teeth throughout life.

Prevents Tooth Grinding

Dental sealants are usually applied to children’s teeth as soon as their back teeth begin erupting, but adults can also receive this preventive treatment. They are especially recommended for those with deep grooves on their molars and premolars, people with a diet high in sugary snacks and drinks, and individuals who have difficulty maintaining good oral hygiene practices.

The process is fast, painless and comfortable. After cleaning and drying the tooth, the dentist applies an acidic gel to the surface of the tooth, which roughens the enamel and creates a better bond for the sealant. After the tooth is dry, the dentist paints the sealant onto the grooved surfaces of the tooth and shines a curing light on it to harden it.

The sealants last for several years, but patients should avoid chewing on hard foods or ice to avoid fractures in the coating. Also, those who clench or grind their teeth may need their sealants reapplied more frequently. The dentist will monitor their condition during regular visits and replace them as needed.

Prevents Stains

A sealant acts as a protective barricade against food and bacteria that gets stuck in the pits, fissures and grooves on the chewing surfaces of back teeth (molars and premolars). They protect these areas by creating a smooth surface for brushing.

The procedure for applying dental sealants is easy, quick and pain-free. A liquid resin is painted on the biting surface of each tooth and hardened with a curing light.

Children with permanent molars benefit from sealants most, but it is also recommended for those who have a high risk of decay on their molars due to frequent snacking or grazing, or who have a difficult time maintaining consistent oral hygiene. Adults with deep molar grooves, a history of cavities or who have a dry mouth can also receive sealants on their teeth to prevent decay.

During the application process, we will thoroughly clean and dry your teeth to prepare them for the sealant. Then, an acid solution is used to roughen the tooth surface and allow the sealant to bond better. The teeth are rinsed and dried again before a final coating of the resin is applied and then hardened with the curing light.

Prevents Gum Disease

Sealants can help children avoid the need for future dental treatments such as fillings and crowns, particularly on their first permanent molars which come through at around six or seven years of age. These molars have deep grooves that can be hard for kids to reach with their toothbrushes and are more susceptible to tooth decay than the front teeth.

The plastic resin of a dental sealant covers the chewing surfaces of these deep grooves to prevent food and acid from seeping in. It creates a protective barrier against plaque, which in turn protects the enamel of the tooth.

The application of a dental sealant is quick, easy and painless. First the dentist will clean and dry the tooth and apply a mild acidic solution to roughen up the surface of the chewing tooth to allow the sealant to adhere to it. The tooth is then rinsed and dried again, before the sealant is applied and allowed to harden using a curing light. The sealant can last for up to ten years before it needs to be reapplied.

Prevents Tooth Wear

Back teeth, especially molars and premolars, are most prone to tooth decay because they’re used to chew and grind foods. They’re also prone to long-term wear from bruxism, which can lead to the enamel and whole tooth being eroded. Sealants can protect these high-risk areas by preventing food and bacteria from penetrating the biting surfaces.

Dental sealants are typically recommended for children, but adults can also receive this safe and painless treatment. Kids can benefit from them as soon as their permanent molars and premolars come in, which usually happens at about 6 and 14 years of age.

While sealants are technically BPA-free, they contain monomers that can turn into BPA when exposed to saliva. However, by scrubbing and rinsing sealants thoroughly after they’re applied, most professionals agree that a person’s exposure to BPA is extremely low.
