Teeth Sealing

Teeth sealing is an important part of preventive dentistry. Molars and premolars have small grooves and fissures or small areas of enamel where a proper brushing is difficult to obtain. They are the perfect environment for food residue and plaque.

Food residue and plaque can cause dental mottling-little streaks on the surface of the tooth, which can easily turn into cavities.

Cavities can be prevented by sealing the teeth, which consists in applying a liquid resin along the surface of the molar which will fill the streaks and indentations, to prevent deposits.

Sealing does not replace proper brushing. After sealing, the teeth must still receive fluoride treatment, may it be in the form of toothpaste or fluoridation in the practice. Sealing and fluorization together prevent the occurrence of cavities.


The first permanent molars erupt around the age of 6, the next set at age 12. Sealing must be done as quickly as possible after the eruption. We strongly recommend teeth sealing before the age of 18. During this time, the mineralization is completed.
