Dental sealants represent a highly effective preventive approach to protecting teeth from cavities, especially for children and individuals in higher-risk groups. Nevertheless, there still exist a considerable number of misconceptions regarding this simple, very effective dental procedure. These myths could be avoided if you knew the facts concerning sealants.

In this blog, we are going to debunk the most common myths about dental sealants. Whether you are considering pit and fissure sealants for your child or are an individual who is looking to protect your own teeth, it is important to know what sealants are and how they could be right for you.

Common Myths about Dental Sealants

Though dental sealants are well recognized as an effective way to protect teeth from caries, several myths persist about their use. This section aims to clear your doubts by revealing the top myths related to pit and fissure sealants:

Myth 1: Sealants Are Only for Children

Probably the most prevalent misconception about dental sealants in Florence is that they can only be used on children. Of course, it’s been noted that children, as well as adolescents, can particularly benefit from having their teeth sealed, since they still have not fully grasped how to take care of their teeth on their own; however, anyone can benefit from a sealant, even adults who may be predisposed to cavities or have especially heavy grooves on their molars.

Sealants can be used to provide added protection against cavities before they occur. Moreover, even with proper oral hygiene practices, having sealants provides added assurance.

Myth 2: They Are Only Useful for People With Cavities

A common misconception is that dental sealants are necessary only if one already has cavities. This is not true; sealants are a preventive treatment that can help protect sound teeth from decay before it develops into a cavity. This is done by applying a material to the grooves on the back teeth, which are prone to cavities.

By applying sealants early, you can create a protective layer that prevents the accumulation of bacteria and food particles, thereby reducing the risk of cavities.

Myth 3: Sealants Only Protect Molars

While molars are the most common teeth to be sealed with pit-and-fissure sealants, they are not the only teeth that need the treatment. In fact, sealants may be used on any set of teeth that has deep grooves, which are highly susceptible to decay. This would be determined by your dentist.

One must bear in mind that the application of sealants is individual. Some individuals may need sealants on their posterior teeth. Others may need them elsewhere.

Myth 4: They Wear Off Quickly

Several individuals think that pit and fissure sealants have a very short lifespan and that it is not worth the trouble. The truth is, sealants can last 5 to 10 years if applied correctly. They can wear off over time due to chewing and brushing, but they can be maintained very easily. 

With regular check-ups, your dentist can check your sealants. Sealants are an investment in your mouth and the prevention of costly procedures, such as fillings and root canals, down the road.

Myth 5: Sealants Are for Those Who Don’t Brush Their Teeth

Others believe sealants should be considered only for those with poor oral hygiene. This is not the case. Anyone who wishes to prevent tooth decay should have sealants applied. This should even include those with excellent oral hygiene who have deep grooves on their teeth that cannot easily be cleaned with brushing alone.

For children, teens, and even adults who tend to develop cavities easily, sealants may be a good supplement to their oral hygiene regimen. This is a preventive measure and not a substitute for regular oral hygiene practices.

Myth 6: They Are Only for People With Specific Dental Problems

Some people believe sealants can work effectively for individuals with grooves in their teeth or cavities. However, the fact is that they aren’t just for people with dental issues. Individuals who want to safeguard their teeth from future cavities should also use pit and fissure sealants. For instance, individuals with cavities should have sealants applied.

Applying sealants regularly helps keep your teeth strong and healthy, reducing the need for more invasive procedures.

Myth 7: Sealants Are Difficult to Apply

Some people do not use dental sealants because they believe the procedure of applying the sealant is complicated or painful. The fact, however, is that it’s very easy, painless, and only takes minutes. The dentist will clean your teeth, apply a specific solution to help the sealant bond to your teeth, and then place the sealant. The whole process will be completed by a light that cures the sealant.

There is no drilling involved, no discomfort, and no recovery time needed. This is a very fast method to make your teeth free from decay.
