How do dental sealants work?

They are most commonly used to protect the top surface of molars, whose deep grooves make them much harder to keep clean.

Luckily, almost all sealants used in modern dentistry consist simply of a layer of clear plastic. This is applied in the form of a liquid, which is then hardened by exposing it to a specific frequency of blue spectrum light.
How long will dental sealants last?
Assuming they are not exposed to any unintended shocks or stresses, dental sealants may be expected to remain in place for between up to ten years. In that time span it is normal to experience some crumbling or flaking of the plastic, and sometimes food can get stuck under the sealant. It's important to have the sealants inspected at regular dental checkups. Patients are recommended to avoid foods that are especially sticky or hard. By placing more stress on the sealant, such foods can negatively affect its lifespan.
What types of people can get dental sealants?
Dental sealants are considered a safe and effective treatment for patients of all ages, children included. In fact, because children are much more cavity prone than adults, dental sealants are most commonly prescribed for 6–14 year olds. Many dentists feel that the ideal time to begin using dental sealants is as soon as the first molars have emerged.
Are dental sealants really necessary?
The answer to this question depends to a large degree on your relationship with risk. While it is possible maintain healthy teeth without the use of dental sealants, they undoubtedly offer a significant measure of protection. Think of sealants as an insurance policy for your teeth.
