Tooth decay is one of the most common dental problems and can affect people of all ages. One of the ways to prevent tooth decay is through the use of tooth sealants.

Tooth sealants help protect the teeth from bacteria, acids, and plaque that can cause cavities. In this article, we will discuss everything you need to know about tooth sealants.

What are tooth sealants?

Tooth sealants are thin coatings that are applied to the surface of the teeth, usually the molars or premolars, to protect them from cavities.

The sealant forms a protective barrier over the tooth’s enamel, preventing bacteria and plaque from entering the uneven surfaces, where food is often trapped.

When should tooth sealants be applied?

Tooth sealants are often applied to children’s teeth as soon as their permanent molars and premolars come in, around age 6 or 7.

This is the most effective time for sealant application because the teeth have just come in and are still healthy and cavity-free. However, adults with healthy teeth can also benefit from sealant application.

What is the process of applying sealants?

The process of applying tooth sealants is quick and easy. The dentist will clean the teeth that need sealing and dry them with air. Then, an acidic solution is applied to the teeth, which helps the sealant bond better to the tooth’s surface.

After a few seconds, the acidic solution is rinsed off and the teeth are dried again. Then, the sealant material is applied to the teeth in liquid form and allowed to flow into the crevices and grooves of the teeth. A special light is then used to harden the sealant, making it a strong and durable protective coating.

How long do tooth sealants last?

Tooth sealants can last for many years, especially if they are properly cared for and maintained. The lifespan of a sealant depends on various factors such as the type of material used, the area of the mouth, and the person’s oral hygiene habits.

Regular dental checkups and cleanings can help to ensure that the sealant remains effective and intact.

Are there any side effects of tooth sealants?

There are no known side effects of tooth sealants. However, some people may experience mild sensitivity or discomfort after the sealant is applied, especially if they have tooth decay or cavities in the tooth’s surface.

These symptoms typically go away after a few days.

Can sealants be placed on teeth with decay or cavities?

No, tooth sealants should only be placed on teeth that are healthy and free of decay or cavities.

If there is already decay or cavities on the tooth’s surface, the dentist will need to clean out the decay and fill the tooth with a dental filling before placing the sealant.

Can tooth sealants be removed?

Tooth sealants can be removed if they become damaged or need replacing. The dentist will use a special dental instrument to gently remove the sealant from the tooth’s surface.

However, once a sealant is removed, the tooth is no longer protected and a new sealant may need to be applied.

How effective are tooth sealants?

Tooth sealants are highly effective in preventing cavities and tooth decay. Studies have shown that the use of tooth sealants can reduce the risk of cavities by up to 80%.

However, tooth sealants should be used in conjunction with good oral hygiene practices such as regular brushing, flossing, and dental checkups.

How much do tooth sealants cost?

The cost of tooth sealants varies depending on various factors such as the number of teeth being sealed, the type of material used, and the dentist’s location. The cost of dental insurance may also cover some or all of the cost of sealants.
