Sealants

Dental sealants offer a fast, painless way to prevent cavities in molars and premolars.

About Dental Sealants

A dental sealant is a thin, plastic coating applied to the chewing surfaces of the back teeth (molars and premolars) to help prevent cavities. The procedure is quick, painless, and very effective in protecting teeth from decay, especially in children and teenagers who may be prone to cavities due to deep grooves in their back teeth.

Dental Sealant Procedure

Here’s a step-by-step overview of the dental sealant procedure:

1. Preparation

  • Evaluation: Dr. Weininger will first examine the teeth to determine if sealants are appropriate, ensuring that there are no existing cavities or decay in the areas to be sealed.
  • Cleaning: The tooth surfaces to be sealed are thoroughly cleaned to remove any plaque or food particles. This ensures that the sealant adheres properly to the tooth.

2. Drying and Isolating the Tooth:

  • Dr. Weininger, the hygienist or assistant will isolate the tooth from saliva to keep it dry during the procedure. This is usually done using cotton or special absorbent material.
  • The tooth is then gently dried with air.

3. Etching

  • An acidic gel is applied to the surface of the tooth to “etch” or roughen it slightly. This helps the sealant bond more effectively to the tooth.
  • The gel is left on the tooth for about 20-30 seconds and then rinsed off thoroughly. The tooth is dried again.

4. Applying the Sealant:

  • A liquid sealant is applied to the grooves and pits of the tooth. This is usually a clear or white resin material.
  • The sealant flows into the grooves and fissures of the teeth, creating a smooth surface to prevent bacteria from accumulating in the grooves, which can lead to cavities.

5. Curing the Sealant:

  • Once the sealant is applied, it is hardened or “cured” using a special UV light or a blue light that causes the resin to harden quickly.
  • This process only takes about 20-30 seconds for each tooth.

6. Final Check

  • Dr. Weininger will check the bite to make sure the sealant doesn’t interfere with the way your teeth come together.
  • Any excess sealant is removed, and the surface is smoothed.

7. Post-Procedure Care:

  • Once the sealant has hardened, the tooth is protected and ready to be used for normal chewing.
  • No special care is needed after the procedure.

How Long Do Sealants Last?

Sealants can last for several years, but they need to be checked regularly during dental visits for any signs of wear or damage. If necessary, we can reapply or repair the sealant.

Benefits of Dental Sealants:

  • Prevent Cavities: Sealants protect the deep grooves of the teeth, which are difficult to clean with a toothbrush.
  • Cost-Effective: Preventing cavities early on is much more affordable than treating a cavity later with fillings or other restorative treatments.
  • Safe and Painless: The procedure is quick, non-invasive, and pain-free.
