Dental Sealants

Dental sealants act as a barrier, protecting the teeth against decay-causing bacteria. The sealants are usually applied to the chewing surfaces of the back teeth (premolars and molars) where decay occurs most often.

How does a sealant help prevent decay?

A sealant is a plastic material that is usually applied to the chewing surfaces of the back teeth—premolars and molars. This plastic resin bonds into the depressions and grooves (pits and fissures) of the chewing surfaces of back teeth. The sealant acts as a barrier, protecting enamel from plaque and acids. Thorough brushing and flossing help remove food particles and plaque from smooth surfaces of teeth.

But toothbrush bristles cannot reach all the way into the depressions and grooves to extract food and plaque. Sealants protect these vulnerable areas by “sealing out” plaque and food.

Is sealant application a complicated procedure?

In Sri Sai Dental Clinic in Coimbatore Sealants are applied very easily. It takes only a few minutes to seal each tooth. The teeth that will be sealed are cleaned. Then the chewing surfaces are roughened with an acid solution to help the sealant adhere to the tooth. The sealant is then ‘painted’ onto the tooth enamel, where it bonds directly to the tooth and hardens. Sometimes a special curing light is used to help the sealant harden.


As long as the sealant remains intact, the tooth surface will be protected from decay. Sealants hold up well under the force of normal chewing and usually last several years before a reapplication is needed. During your regular dental visits at Sri Sai Dental Clinic Coimbatore , your dentist will check the condition of the sealants and reapply them when necessary.

How Long do Sealants Last?

The amount of time your sealant can last can vary from person to person. Generally, a period of 3 to 5 years is considered successful. Sealants however, can last for much longer, and it’s quite common to find sealants placed as children still existing as adults. While sealant itself can last for many years, you may need to get it checked regularly and replace it in case of wearing out. Remember that a dental sealant is effective only as long as it is fully intact. If you notice parts of the sealant are coming off, inform your dentist at Sri Sai Dental Clinic in coimbatore  immediately. We  will also check on the status of your sealants during your regular dental check ups.

Sealants are just for kids, right?

The likelihood of developing pit and fissure decay begins early in life, so children and teenagers are obvious candidates. But adults can benefit from sealants as well. Best Dentist At Sri Sai Dental Clinic, Coimbatore is perfectly equipped to inform you about whether dental sealants are indicated. In some people, the natural shape of the pits and fissures puts  them at higher risk for the development of cavities. 

For instance, if the pits and fissures in your teeth are narrow and deep, then you need dental sealants more urgently than people who have shallow and round grooves. Your Dentist At Sri Sai Dental Clinic, Coimbatore  may also evaluate other conditions that reveal the amount of risk for tooth decay. He will look at the amount of dental plaque on the teeth, and the amount of decay the teeth have experienced earlier. He will also evaluate the patient’s exposure to adequate amounts of fluoride, before recommending a sealant.
