When Should Dental Sealants Be Applied? A Guide for Parents

Back to Blog

Dental sealants are thin, plastic coatings that are applied to the chewing surfaces of the back teeth (molars and premolars). These teeth have pits and grooves that make them vulnerable to decay because they can trap food particles and bacteria. Sealants act as a barrier, protecting the teeth from plaque and acids that can cause cavities. The application of sealants is a quick and painless process that can be done by a dentist or dental hygienist. The sealant material is applied to the tooth surface and then hardened with a special light, creating a protective shield over the enamel.

Dental sealants are typically clear or tooth-colored, making them virtually invisible when applied to the teeth. They are most commonly used on the molars and premolars of children and teenagers, as these are the teeth most susceptible to decay. However, adults can also benefit from sealants if they have deep grooves or pits in their teeth that are at risk for decay. Overall, dental sealants are a simple and effective way to prevent cavities and maintain good oral health.

The benefits of dental sealants for children

Dental sealants offer numerous benefits for children, making them an important part of preventive dental care. One of the main advantages of sealants is their ability to protect the teeth from decay. The chewing surfaces of the back teeth are often difficult to clean thoroughly with a toothbrush, making them more prone to cavities. Sealants provide a smooth surface that makes it easier to keep these areas clean and free from plaque buildup.

In addition to preventing cavities, dental sealants can also save families money in the long run. The cost of applying sealants is much lower than the cost of treating cavities, fillings, or other dental procedures. By investing in sealants for their children, parents can help avoid the need for more extensive and expensive dental work down the road. Furthermore, sealants can help children avoid the discomfort and inconvenience of toothaches and other dental problems, allowing them to maintain good oral health and focus on their daily activities without interruption.

When is the best time to apply dental sealants?

The best time to apply dental sealants is as soon as the permanent molars and premolars have erupted in a child’s mouth. This typically occurs between the ages of 6 and 12. The first set of molars usually come in around age 6, with the second set appearing around age 12. It is important to apply sealants as soon as possible after these teeth have erupted to provide maximum protection against decay.

In some cases, dentists may also recommend applying sealants to baby teeth if they have deep grooves or pits that put them at risk for decay. This can help protect the baby teeth until they naturally fall out and are replaced by permanent teeth. Overall, the best time to apply dental sealants is during childhood when the teeth are most vulnerable to decay and when preventive measures can have the greatest impact on long-term oral health.

How long do dental sealants last?

Dental sealants can last for several years with proper care and maintenance. On average, sealants can remain effective for 5-10 years before they need to be reapplied. However, it is important for individuals to visit their dentist regularly for check-ups to ensure that the sealants are still intact and providing adequate protection.

The lifespan of dental sealants can vary depending on factors such as oral hygiene habits, diet, and the individual’s bite pattern. Chewing on hard objects or eating sticky foods can cause wear and tear on the sealants, reducing their effectiveness over time. Additionally, poor oral hygiene practices can lead to plaque buildup around the sealants, increasing the risk of decay. Regular dental check-ups can help identify any issues with the sealants early on and allow for prompt reapplication if necessary.

Are there any risks or drawbacks to dental sealants?

While dental sealants offer numerous benefits, there are some potential risks and drawbacks to consider. One concern is that some people may be allergic to the materials used in sealants, although this is rare. It is important for individuals to inform their dentist of any known allergies before getting sealants applied. Additionally, there is a small risk of bacteria becoming trapped under the sealant if it is not properly applied, potentially leading to decay.

Another drawback of dental sealants is that they only protect the chewing surfaces of the back teeth, leaving other areas vulnerable to decay. It is still important for individuals to maintain good oral hygiene habits, including brushing and flossing regularly, to prevent cavities in other areas of the mouth. Furthermore, while sealants are effective at preventing cavities, they do not provide protection against gum disease or other oral health issues.

How to prepare your child for getting dental sealants

Preparing your child for getting dental sealants can help ease any anxiety or fear they may have about visiting the dentist. It is important to explain to your child what dental sealants are and why they are beneficial for their oral health. You can reassure them that getting sealants is a quick and painless process that will help keep their teeth strong and healthy.

It can also be helpful to talk to your child about what to expect during the appointment. Let them know that the dentist will clean and dry their teeth before applying the sealant material, which will then be hardened with a special light. Assure them that there will be no discomfort during the procedure and that they will be able to return to their normal activities right away.

Finally, you can offer your child a small reward or treat for being cooperative during the appointment. This can help create a positive association with visiting the dentist and getting preventive dental care. By taking these steps to prepare your child for getting dental sealants, you can help ensure that they feel comfortable and confident about maintaining good oral health.

The importance of regular dental check-ups after getting dental sealants


After getting dental sealants, it is important for individuals to continue visiting their dentist regularly for check-ups and cleanings. These appointments allow the dentist to monitor the condition of the sealants and ensure that they are still providing adequate protection against decay. If any issues with the sealants are identified, such as wear or damage, they can be addressed promptly to prevent cavities from developing.

Regular dental check-ups also provide an opportunity for the dentist to assess overall oral health and address any other concerns that may arise. This includes checking for signs of gum disease, oral cancer, or other oral health issues that may not be visible to the individual. Additionally, professional cleanings can help remove plaque and tartar buildup that may have accumulated around the sealants, reducing the risk of decay.

By maintaining regular dental check-ups after getting dental sealants, individuals can ensure that their oral health remains in optimal condition. This proactive approach allows for early detection and intervention if any issues arise, helping to prevent more serious dental problems in the future. Overall, regular dental check-ups are an essential part of maintaining good oral health for individuals who have received dental sealants.
