Dental Sealants

Dental Sealants

Dental sealants are thin, protective coatings applied to the chewing surfaces of molars and premolars to prevent decay. Made from plastic materials, they bond to the grooves and pits of teeth, creating a barrier that blocks out bacteria and food particles, thus reducing the risk of cavities.

Sealants are particularly beneficial for children and teenagers, whose developing teeth are more vulnerable to decay. They are a non-invasive, painless preventive measure that can significantly decrease the likelihood of future dental issues, saving time and money in the long run by avoiding more extensive treatments like fillings or root canals. Regular dental check-ups with our dentist in New York, NY, are essential to ensure sealants remain intact and effective over time.

Who Can Benefit from Dental Sealants?

Children and Teenagers

Preventive Measures During Tooth Development 

Children and teenagers are at a crucial stage of tooth development where their permanent molars and premolars erupt. These newly erupted teeth often have deep grooves and pits that are difficult to clean thoroughly with regular brushing. As a result, they are more prone to decay. 

Reduced Risk of Cavities 

Applying dental sealants to the chewing surfaces of these newly erupted teeth provides an added layer of protection against cavities. By sealing off the deep grooves and pits, sealants prevent bacteria and food particles from accumulating and causing decay. Contact us today to learn more!

Promotion of Lifelong Oral Health 

Introducing dental sealants at a young age sets the foundation for a lifetime of good oral health habits. Children who receive sealants early are less likely to experience cavities and dental issues in the future, leading to healthier smiles well into adulthood. 


Addressing Deep Grooves and Pits 

While dental sealants are commonly associated with pediatric dentistry, adults with deep grooves and pits in their molars can also benefit from sealant application. These deep crevices can harbor bacteria and food debris, increasing the risk of decay, even in individuals who maintain good oral hygiene.

Preventing Future Dental Problems 

Adults opting for sealants can proactively protect their teeth from cavities and other dental issues. This preventive measure can save them from the discomfort and expense of undergoing more extensive treatments such as fillings or root canals down the line. 

Preservation of Natural Teeth 

Dental sealants in New York, NY, contribute to preserving natural teeth by fortifying them against decay. By maintaining the integrity of the tooth structure, sealants help adults retain their natural teeth for longer, promoting overall oral health and well-being. 

The Process of Applying Dental Sealants 

  • Our dentist at L.E.S. Dental Group begins by cleaning and drying the teeth that will receive the sealants. This ensures that the sealant adheres properly to the tooth surface. 
  • The teeth receiving the sealant are isolated using cotton rolls or a rubber dam. This helps keep the area dry during application, ensuring better sealant adhesion. 
  • A mild acidic solution or gel is applied to the chewing surfaces of the teeth for a short period. This etches the enamel, creating a rough surface that allows the sealant to bond more effectively to the teeth. 
  • After removing the etching solution, the teeth are thoroughly rinsed and dried again to remove any residual moisture. 
  • The sealant material, usually a liquid resin, is carefully applied to the grooves and pits of the teeth using a small brush or applicator. It flows into the tiny crevices of the enamel, creating a protective barrier. 
  • A special curing light may be used to harden the sealant and ensure it bonds securely to the tooth surface. This process typically takes only a few seconds per tooth.
  • Once the sealant has hardened, the dentist checks its placement and makes any necessary adjustments to ensure proper coverage and alignment.
  • The dentist evaluates the bite and overall comfort to ensure the sealants do not interfere with normal chewing or cause any discomfort.
  • Patients are typically advised to avoid chewing sticky or hard foods immediately after sealant placement to allow the material to set fully. Regular oral hygiene practices, including brushing and flossing, should be maintained to keep the sealants and surrounding teeth clean and healthy. 
  • Regular dental check-ups are recommended to monitor the condition of the sealants and ensure they remain intact and effective over time. Sealants may need to be reapplied or touched up if worn or damaged. 

The Benefits of Dental Sealants 

Cavity Prevention 

Dental sealants help prevent cavities by forming a protective barrier that blocks out bacteria and food debris, especially in hard-to-reach areas where toothbrush bristles may not effectively clean. 


Investing in dental sealants is a proactive approach to oral health that can save time and money in the long run. Sealants reduce the need for more extensive and costly dental treatments such as fillings or root canals by preventing cavities. 

Painless and Non-Invasive 

Unlike other dental procedures, applying dental sealants is painless and non-invasive, making it an ideal preventive measure for individuals of all ages, particularly children and teenagers. 

Long-Lasting Protection

Dental sealants can provide long-lasting protection against decay with proper care and maintenance. Regular dental check-ups help ensure sealants remain intact and effective over time.
