Why is the occlusal surface prone to dental caries?

Most of the children's permanent teeth begin to sprout around the age of 6-7, starting with the first molar. On the occlusal surface of molars, there are many pits and fissures that are not easy to clean, which are easy to accumulate food residues and bacteria, so that the teeth have the potential risk of caries.

What are pit-and-fissure sealants

Pit-and-fissure sealants refer to the use of sealants to fill these gaps before the molar completely erupts and the pit and fissure on the tooth surface has not been eroded, which can prevent the invasion of food residues and bacteria and prevent caries.

How to do sealing?

The dentist will clean the teeth to be treated. After surface treatment and drying, he/she applies pit-and-fissure sealants. After the sealant hardens, it will be like wearing bullet proof protective clothing for molars!
