Answer 1

There are several kinds of bacteria which are present in a tooth which is unhygienic or is not clean, the role of the bacteria is to convert the sugar or the leftover food in the tooth into a lactic acid.

When the acid is formed it decays the enamel on the tooth and this also affects dentin. Another bacteria which is produced in the tooth is known as plaque which affects the enamel of the tooth too.
