The main reason for decay is the food and bacteria that are trapped in the pits & fissures of teeth. We chew food from the back teeth like molars and premolars which are never flat. The pits & fissures as discussed above are the depressions on these back teeth.
They function as potential traps for bacteria & food and make it susceptible to decay. So, as a preventive measure, certain pits and fissure sealants are placed over the deep fissure.
Dental sealants then come to the rescue. Sealants are plastic coatings placed on the chewing surface of the permanent tooth. They protect the tooth from decay. Because of fissures the permanent back teeth, molars, and premolars are vulnerable to decay.
As we talked about the habits, it is important to inculcate the habit of maintaining good oral health at a very initial stage. This is an investment that will pay lifelong dividends in the form of healthy teeth and a healthy lifestyle. Parents should take initiatives to teach their children the correct brushing technique and for that, they must know the correct way of brushing & make it a fun-filled activity for your child, brush along with them, and encourage them to take preventive actions.
