Young milk and permanent teeth are more sensitive to acid. In addition, since the structure of these teeth is more permeable than adult teeth, tooth decay occurs more easily and the resulting decay progresses faster. 

Studies show that 4 out of every 5 caries occur on the chewing surfaces of the posterior molars. The reason for this is the deep recesses on the surfaces of the teeth. On the chewing surface of the primary and permanent molars of children, there is a mound and deep pit-like structure called tubercle and fissure. It is very difficult for the brush bristles to reach the bottom of these deep recesses and clean these areas. It is possible to protect the teeth from caries by closing the pits of these molars and protecting them from acid and plaque. It is important to perform 'Fissure Sealant' applications, commonly known as 'Tooth Polish', and 'Superficial Fluoride Applications', which have an important role in protecting all tooth surfaces from caries.

Fissure sealants are applied once, they do not need to be repeated. But they need to be checked.

After the age of 3.5, it is possible to protect your child from dental caries by making these preventive applications and checking them regularly. Caries-protective methods that are suitable for your child's own tooth structure, saliva structure and nutritional habits should be determined, their application and control should be done regularly.
