Dental sealants are thin protective coatings applied to the chewing surfaces of back teeth to prevent cavities and block decay. Our dentist applies this quick, painless treatment to shield your teeth and protect your overall oral health. Dental sealants seal deep grooves, stop bacteria from settling in, and keep your teeth cavity-free and healthy for a lifetime.
At Pasadena Dental Office and Orthodontics, our dentist evaluates the chewing surfaces of premolars and molars during routine exams to determine whether dental sealants can help prevent decay in deep pits and fissures that a toothbrush cannot effectively reach. The tooth surface is cleaned, conditioned with a mild etching solution, and painted with a resin-based sealant that flows into the grooves and is hardened with a curing light to form a durable protective barrier. Dental sealants block plaque, bacteria, and acid from penetrating enamel and can reduce the risk of cavities in treated teeth. If you or your child is due for a preventive care visit, contact our office to find out if dental sealants are the right next step.
Dental sealants are thin protective coatings applied to the chewing surfaces of back teeth. They act as a barrier over the deep grooves and pits found on molars and premolars, areas of the tooth that are naturally difficult to keep clean.
Dental sealants provide several preventive benefits for protecting back teeth from decay.
Benefits include:
Dental sealants prevent about 80% of cavities in molars within the first two years after placement.
We recommend dental sealants if your molars have deep grooves or you’re prone to cavities. They’re especially beneficial for children and teenagers as their permanent molars come in, but adults with deep pits in their back teeth or a history of tooth decay can benefit just as much. If you need a little extra support in keeping your smile healthy, sealants are a great option for you.
Dental sealants are made from safe, durable materials designed to bond to the enamel and create a protective barrier against tooth decay.
Common materials include:
Applying dental sealants is a quick and painless procedure that is often completed in one visit. The goal is to clean and prepare the tooth before sealing the grooves where decay commonly begins.
Dental sealant treatment depends on the condition of the tooth and the patient’s risk for cavities. We will examine the chewing surfaces of the back teeth and recommend the most effective preventive treatment to protect enamel and support long-term oral health.
Resin-based dental sealants are commonly recommended for molars and premolars with deep pits and grooves that easily trap plaque and food. The material is applied directly to the chewing surface, where it hardens into a smooth protective layer that blocks bacteria and reduces the risk of decay.
Glass ionomer sealants may be recommended for patients who would benefit from added fluoride release along with cavity protection. These sealants help protect the tooth surface while also supporting enamel strength, making them useful in patients with a higher risk of decay.
When permanent molars first erupt, they are especially vulnerable to plaque buildup and cavity formation. Dental sealants are often placed early to protect these new teeth by sealing the grooves before bacteria and acid can begin damaging the enamel.
Adults with deep grooves, a history of cavities, or areas that are hard to clean may also benefit from sealants. This preventive treatment helps reduce the chance of future decay and supports a more conservative approach to dental care.
If an older sealant becomes chipped, worn down, or partially lost over time, a dentist can evaluate the area and repair or replace the material. Maintaining full coverage helps continue the protective benefit of sealing vulnerable tooth surfaces.

Contact us today to schedule your appointment and take the first step toward stronger cavity protection and a healthier smile.
There is little to no recovery time after getting dental sealants. Most patients can return to normal daily activities right away, and the treated teeth are ready to function normally soon after the material hardens.
Dental sealants are not always required for every patient, but they are often strongly recommended for children, teens, and adults with cavity-prone molars. In preventive dentistry, sealants are used to lower the risk of decay in areas that are difficult to clean well with brushing alone.
In some cases, teeth sealants may be placed over very early, small areas of tooth decay to help stop the cavity from getting worse. However, if the cavity is larger or has already weakened the tooth, another treatment such as a filling may be more appropriate.
Dental sealants are generally very safe and well-tolerated. Some patients notice a slightly different texture on the chewing surface at first, but this usually goes away quickly as the bite adjusts.
Some dental sealant materials may contain trace amounts of Bisphenol A (BPA) related compounds, but the amount is extremely low. Research has shown that exposure to dental sealants is minimal, and they are widely considered safe for use in preventive dental care.
With proper oral care, tooth sealants typically last 5 to 10 years before needing to be replaced, according to the American Dental Association. Their lifespan depends on your chewing habits, oral hygiene, and everyday wear over time. During your regular visits, we’ll check that your sealants are still intact and reapply them as needed. If one becomes worn or chipped, we can repair or replace it quickly to keep your tooth protected.
