A fissure sealant is a liquid plastic-based protective material that seals the deep grooves and pits on the chewing surfaces of molars. It is popularly known as a "tooth vaccine". By smoothing the tooth surface, it stops bacteria settling in grooves a toothbrush cannot reach and aims to reduce the future need for fillings or root canal treatment.
- It is usually started when the first permanent molars erupt; the ideal age is 6–12.
- Application: cleaning, preparation with gel, filling with sealant and light curing.
- No needle is needed because no drilling is done.
- A filling treats a decayed tooth; a fissure sealant protects a healthy tooth.
- Worn areas can be renewed at six-monthly check-ups.
What is a fissure sealant? A fissure sealant is actually a liquid plastic-based material that seals the deep grooves and pits on the chewing surfaces of molars. Also popularly known as a "tooth vaccine" or "tooth sealing", this procedure smooths the tooth surface and prevents bacteria from settling in these areas.
Why Should Fissure Sealants Be Applied?
The chewing surfaces of teeth have anatomical grooves so narrow and deep that toothbrush bristles cannot reach them. These areas are the favorite spots of decay-causing microorganisms. Fissure sealants:
-
Seal the most vulnerable area of the tooth against bacteria.
-
Make brushing more effective and easier.
-
Minimize the future need for painful and costly fillings/root canal treatment.
How Is a Fissure Sealant Applied? (Step by Step)
The procedure is very short and completely painless. It does not require anesthesia (a needle):
-
Cleaning: The tooth surface is cleaned with special brushes.
-
Preparation: A special gel is applied to the tooth surface and rinsed off so the sealant can adhere.
-
Application: The fissure sealant, in flowable form, is filled into the grooves.
-
Curing: The material is hardened within seconds with a blue light (curing light).
Frequently Asked Questions About Fissure Sealants (FAQ)
1. At what age are fissure sealants applied? It usually starts when the first permanent molars, which we call the 6-year molars, erupt. Between the ages of 6 and 12, when the permanent teeth are coming in, is the ideal time for application.
2. Does the child feel pain during the procedure? No, there is absolutely no pain. Because no drilling is done on the tooth, there is no need for an injection. It is a wonderful "introductory" treatment to help children overcome their fear of the dentist.
3. What is the difference between a fissure sealant and a filling? A filling is done to treat a decayed tooth. A fissure sealant, on the other hand, is a protective procedure done to prevent a healthy tooth from decaying.
4. How long do sealants stay on the teeth? When applied correctly and not strained by hard foods, they can last for years. However, if there are worn areas at routine six-monthly check-ups, the dentist can easily renew them.
5. How much do fissure sealants cost in 2026? Fissure sealant prices vary depending on the number of teeth to be treated and the quality of the material used. However, it should not be forgotten that preventive treatments are always much more economical than fillings or root canal treatment.
