What are dental Sealants?

In dentistry, many protective measures can be used to prevent dental problems in the long-term. Dental sealants are classified as one of the prominent dental protective options for young and older adults.

Dental sealants are a thin layer of plastic coating applied on the biting surface of permanent molars and premolars. They provide long-term protection, so dental sealants are mainly for people who have already developed permanent teeth.

How they work?

Dental sealants provide a thin layer of coating that prevents bacteria or plaque from causing damage to your teeth. The dental structure of some people features premolars and molars which have deep fissures and depressions. These areas provide a festering place for bacteria and plaque. In many cases, bacteria in these fissures cannot be eliminated by brushing because of the deep grooves. However, dental sealants cover the surface of the depressions to prevent bacteria or plaque from entering these parts of the teeth.

Who needs dental sealants?

Dental sealants can be used by young children and adults. Children between the age of 6 and 14 years are prone to having cavities in their teeth. This age group is most likely recommended for dental sealants.

Adults can also have dental sealants applied if they do not already have cavities or signs of tooth decay. If you are not sure of your dental condition, you can visit a dental clinic. There are professional ways of determining if you are prone to suffer cavities or tooth decay in the future. If the tendency of such dental issues happening is high, you will be advised to have dental sealants applied over the biting surface of your teeth.

Benefits of dental sealants:

Dental sealants can help people avoid many dental problems.

Tooth decay

Dental sealants are used to protect the teeth of children as young as six years old. When properly applied, dental sealants significantly reduce the occurrence of tooth decay over a long time.

Prevention of cavities

Dental sealants provide a protective covering over the surface of the teeth. This thin layer of plastic prevents bacteria from entering the deep fissures in your teeth. Bacteria produce acids that can damage the internal parts of your teeth, and that is how dental cavities are formed. Over time, the cavities become bigger, and you can lose the tooth. However, dental sealants reduce the chances of cavities forming.

Protection against plaque

Dental sealants prevent food particles from becoming lodged in the deep fissures in your teeth. This reduces the chances of those small food particles to promote the growth of plaque.

Tooth decay and other dental issues caused by bacteria can cause pain and discomfort. People who suffer these issues have difficulty in sleeping, eating, and may lose some days off work because of the pain. This is why you should consider having dental sealants applied early to protect your teeth.

No worries, the process of fixing dental sealants is painless. The thin protective layer hardens quickly, and you can eat normally soon after the procedure. Dental sealants last for as long as ten years; your dentist will inform you when it needs to be replaced.

Dental sealants give you peace of mind. However, they should be applied early, before tooth decay or cavities start forming. It is also important you maintain your normal dental hygiene by brushing your teeth every day.
