Dental sealants are a common preventive dental treatment that can help protect teeth from decay. While they are often associated with children, dental sealants can also be beneficial for adults. In this article, we will explore some common questions about dental sealants for adults and provide valuable insights based on research and expert opinions.

What are dental sealants?

Dental sealants are thin, plastic coatings that are applied to the chewing surfaces of the back teeth, also known as molars and premolars. These teeth have deep grooves and pits that can be difficult to clean properly, making them more susceptible to decay. Sealants act as a barrier, protecting the teeth from bacteria and acids that can cause cavities.

The process of applying dental sealants is quick and painless. The tooth is thoroughly cleaned, and an acidic gel is applied to roughen the surface, allowing the sealant to bond more effectively. The gel is then rinsed off, and the tooth is dried. Finally, the sealant is applied and hardened using a special light.

Why are dental sealants important for adults?

While dental sealants are commonly associated with children, they can also be beneficial for adults. Here are some reasons why dental sealants are important for adults:

  • Protection against decay: Adults can still develop cavities, especially in the hard-to-reach areas of the back teeth. Dental sealants provide an extra layer of protection, reducing the risk of decay.
  • Prevention of tooth sensitivity: As we age, the enamel on our teeth can wear down, leading to increased tooth sensitivity. Dental sealants can help protect the exposed dentin and reduce sensitivity.
  • Saving time and money: Preventive treatments like dental sealants can help avoid the need for more extensive and costly dental procedures in the future.

Who is a good candidate for dental sealants?

Not everyone may benefit from dental sealants. Here are some factors that can determine if you are a good candidate for dental sealants:

  • Deep grooves and pits: If your back teeth have deep grooves and pits, you may be more prone to developing cavities. Dental sealants can help protect these vulnerable areas.
  • History of cavities: If you have a history of cavities, dental sealants can be an effective preventive measure to reduce the risk of future decay.
  • Poor oral hygiene: If you struggle with maintaining good oral hygiene or have difficulty reaching the back teeth with your toothbrush, dental sealants can provide an added layer of protection.

How long do dental sealants last?

The longevity of dental sealants can vary depending on various factors, including the quality of the sealant material and how well they are maintained. On average, dental sealants can last up to 10 years. However, regular dental check-ups are essential to monitor the condition of the sealants and ensure they are still intact.

It is important to note that dental sealants are not permanent. Over time, they may wear down or chip off, requiring reapplication. Your dentist will assess the condition of the sealants during your routine dental visits and recommend reapplication if necessary.

Are there any risks or side effects associated with dental sealants?

Dental sealants are considered safe and have minimal risks or side effects. However, it is essential to be aware of the following considerations:

  • Allergic reactions: In rare cases, individuals may have an allergic reaction to the materials used in dental sealants. If you have a known allergy to certain plastics or resins, it is important to inform your dentist before getting sealants.
  • Temporary sensitivity: Some individuals may experience temporary tooth sensitivity after getting dental sealants. This sensitivity usually subsides within a few days.
  • Sealant retention: While dental sealants are designed to adhere to the tooth surface, there is a small chance of partial or complete loss of the sealant over time. Regular dental check-ups can help identify any issues with sealant retention.


Dental sealants are a valuable preventive treatment that can benefit adults by protecting their teeth from decay and reducing the risk of cavities. They are particularly beneficial for individuals with deep grooves and pits on their back teeth or a history of cavities. While dental sealants can last for several years, regular dental check-ups are necessary to monitor their condition and ensure they are still providing adequate protection.

If you are considering dental sealants, it is best to consult with your dentist. They can assess your oral health and determine if dental sealants are a suitable option for you. Remember, prevention is always better than treatment when it comes to maintaining good oral health.
