Why Doctor Yu is for You!


Applying sealants during childhood will protect the teeth throughout the most cavity-prone years because sealants can last for many years if properly cared for. Sealants will last longer if you maintain good oral hygiene and avoid biting hard objects. During routine dental visits the dentist will check the sealants and may recommend reapplication or repair when necessary.


  • Prevent food and plaque from gathering in tooth surface grooves and depressions.
  • Reduce risk of decay, leave bacteria no place to grow.
  • More cost effective than treating cavities.
  • Quick, painless application, protects for up to 10 years.

Enamel Protection at it’s Finest

Sealants are highly effective in preventing tooth decay on your molars and premolars. These areas are the most susceptible to decay due to the anatomized grooves.

Typically, children get sealants on their permanent molars and premolars as soon as these teeth erupt fully. These sealants can protect the teeth through the cavity-prone years of ages 6 to 14. However, adults without decay or fillings in their molars can also benefit from sealants.

The process of applying sealants is easy and fast. The application steps are as follows:

  • We thoroughly clean the teeth.
  • The teeth are dried.
  • A liquid solution is put on the chewing surfaces of the teeth.
  • The solution is cured using a special curing light.

Sealants act as a barrier and protect the enamel from plaque and acids. They may last for several years before a reapplication is needed. While the sealant remains intact, the tooth surface will be protected from decay.

Sealants are not a substitute for brushing your teeth. It is important to maintain proper oral hygiene and keep up with professional dental cleanings. Also, sealants do not protect between the teeth, so it is essential to continue to floss daily.
