What Are the Advantages & Disadvantages of Dental Sealants?

May 1, 2024

Taking preventative steps is very important for keeping your mouth health in the best shape possible when it comes to dental care. More and more, both dentists and customers are realizing how useful preventative care like tooth sealants can be. These thin coats are put on the eating sides of molars and premolars to keep teeth from getting cavities. However, like any dental procedure, dental sealants come with their own set of advantages and disadvantages. Let's dive into the details to understand them better.

Introduction to Dental Sealants

As a protective step, dental sealants are used to keep teeth from getting cavities. They are typically made of plastic or other dental materials and are applied to the chewing surfaces of the back teeth, namely, molars and premolars. These areas are prone to decay due to their deep grooves and pits, which can easily trap food particles and bacteria, resulting in cavities. By sealing off these vulnerable areas, dental sealants act as a barrier, preventing bacteria from causing decay.

Advantages of Dental Sealants

  • Effective Decay Prevention: One of the best things about dental sealants is that they keep teeth from getting cavities. To make the biting surface of teeth smooth, sealants are filled in the deep grooves of the teeth. This makes it less likely for bacteria to grow. This greatly decreases the likelihood of cavities in these regions.
  • Non-Invasive Procedure: Unlike some dental treatments that involve drilling or removal of tooth structure, applying dental sealants is a non-invasive procedure. The process typically involves cleaning the tooth surface, applying an adhesive material, and placing the sealant over the tooth. This makes it a relatively quick and painless procedure.
  • Cost-Effective: Dental sealants offer a cost-effective preventive approach when compared to the treatment of dental caries or cavities. While the initial cost of sealant application may vary depending on the dental practice and location, it is generally lower than the cost of restorative treatments, including fillings or root canals.
  • Long-lasting Protection: With maintenance and consistent care, dental sealants near you can provide long-lasting protection against tooth decay. While they may wear down over time due to chewing and other factors, they can often last for several years before needing to be replaced.
  • Suitable for All Ages: Dental sealants are not limited to children and adolescents. While they are commonly applied to the permanent teeth of pediatric patients, adults can also benefit from sealant application, especially if they are at a higher risk of developing cavities.

Disadvantages of Dental Sealants

  • Not a Cure for Existing Decay: While dental sealants are effective in preventing new cavities, they do not treat existing tooth decay. If decay is already present in a tooth, it must be addressed through restorative treatments such as fillings or crowns before sealants can be applied.
  • Limited Coverage: Dental sealants only protect the chewing surfaces of molars and premolars. They do not shield the entire tooth surface or the areas between teeth, leaving those areas vulnerable to decay. Therefore, maintaining good oral hygiene practices like brushing, flossing, and regular dental check-ups is still essential.
  • Potential for Sealant Wear and Damage: Over time, dental sealants may wear down or become damaged due to normal chewing and biting forces. While this is a gradual process, it can eventually compromise the effectiveness of the sealant and increase the risk of decay in the protected teeth.
  • Risk of Allergic Reactions: Although uncommon, some individuals might encounter allergic reactions to the materials utilized in dental sealants. It is essential for dental patients to inform their dentist in Santa Rosa of any known allergies or sensitivities before undergoing sealant application.
  • Difficulty in Application: While dental sealant application is generally straightforward, it can be challenging in some cases. Factors such as tooth anatomy, moisture control, and patient cooperation can affect the success of the procedure. In such instances, additional measures may be necessary to ensure proper sealant placement.

Candidacy for Dental Sealants

While dental sealants are beneficial for individuals of all ages, They are especially advised for children and teenagers who have an increased susceptibility to developing cavities. Factors such as tooth anatomy, oral hygiene habits, and susceptibility to decay determine eligibility for sealant application. Consultation with a dentist near you in Santa Rosa is essential to assess candidacy and discuss the benefits of sealants.

Comparing Dental Sealants with Other Preventive Measures

  • Dental Sealants Vs. Fluoride Treatments: While fluoride treatments strengthen tooth enamel, sealants provide a physical barrier against decay.
  • Dental Sealants Vs. Dental Fillings: Sealants are a preventive measure, whereas fillings are used to treat existing cavities. Sealants offer proactive protection against decay, while fillings address cavities after they develop.

Maintenance and Care of Dental Sealants

  • Daily Cleaning Routines: Brushing twice a day with fluoride toothpaste and flossing regularly helps maintain sealants' integrity.
  • Avoiding Staining and Odor: Limiting consumption of sugary and acidic foods and beverages can prevent staining and odor buildup on sealants.
  • Regular Dental Check-ups: Routine dental visits allow the dentist in Santa Rosa to monitor the condition of sealants and recommend reapplication or repairs as needed.


Dental sealants offer significant advantages in preventing tooth decay, especially in the hard-to-reach areas of molars and premolars. They are a non-invasive, cost-effective, and long-lasting preventive measure suitable for patients of all ages. However, it is essential to take into account the limitations and potential drawbacks of sealants, such as their inability to treat existing decay and the risk of wear and damage over time. In the end, getting dental sealants should only be decided after talking to a dentist and thinking about your specific oral health wants and tastes.
