Sealants: What are they and how do they help?

Dental Sealants

Molars, with their intricate canyons, caves, and pits, can be challenging to keep cavity-free. These hidden spaces provide the perfect breeding ground for decay, posing a constant threat to dental health. Thankfully, modern dentistry offers a protective solution: dental sealants. When applied correctly, sealants can effectively shield your teeth from cavities. Let’s delve into what dental sealants are, how they work, and why they’re a valuable investment in your oral health.

Understanding Dental Sealants:

Dental sealants are thin coatings made of composite material, resembling plastic, infused with bonding agents. They are designed to seal the chewing surfaces of molars, preventing food particles from becoming trapped in the intricate grooves and fissures. This proactive measure inhibits the growth of decay-causing bacteria, reducing the risk of cavities.

The Process of Sealant Application:

The application of dental sealants is a precise and painless procedure, typically performed by skilled dental professionals like Dr. Batistas of Gainesville Dental Associates. Here’s an overview of the process:

  1. Cleaning and Preparation: The tooth surface is thoroughly cleaned using a sodium bicarbonate (baking soda) spray to remove any debris or bacteria.
  2. Surface Etching: An acid etch is applied to the tooth surface to create a slightly roughened texture, enhancing the bond between the sealant and the tooth enamel. It’s essential to keep the tooth dry during this stage to ensure optimal adhesion.
  3. Application of Sealant: The sealant material is carefully applied to the grooves, pits, and fissures of the tooth surface, guided by the dental professional to ensure comprehensive coverage.
  4. Curing Process: Once applied, the sealant is cured or hardened using a special light. This transforms the material into a durable, plastic-like substance that effectively seals off the tooth surface.

Benefits and Maintenance:

Dental sealants offer several benefits:

  • Preventive Protection: By sealing off vulnerable areas of the teeth, sealants act as a barrier against cavity-causing bacteria, reducing the likelihood of decay.
  • Longevity: Sealants can last for several years with proper care and maintenance, providing lasting protection for your teeth.
  • Minimal Maintenance: Routine dental check-ups are recommended to monitor the condition of the sealants. If any damage or wear is detected, repairs can be performed quickly and painlessly.
  • Suitability for All Ages: While children often receive sealants as part of routine preventive care, adults with deep grooves and fissures on their molars can also benefit from sealant application.


Investing in dental sealants is a proactive step towards safeguarding your oral health and preserving your natural teeth.
