Primary and young permanent molar teeth are very susceptible to development of decay, particularly on their chewing surfaces. Young permanent molar teeth, soon after their eruption, are still immature and take several months to mature completely. This time period is very critical and at this time period we should protect the tooth from decay.

Fluoride, even though it prevents decay by strengthening the enamel, cannot prevent decay on the chewing surface of the molar teeth by the same mechanism. Hence a specially available cement called pit and fissure sealantscan be used to cover and seal those risky, deep chewing surfaces of molars. This will prevent entrapment of food particles in them and thereby prevent tooth decay. These pit and fissure sealants don�t need a tooth drill before its placement. It is a very simple procedure to perform and has great preventive benefit.

Professional fluoride treatment, pit and fissure sealants, good oral hygiene and brushing can reduce decay formation to a great extent.
