Babies teeth start to show when they are six or seven months old.
Most children will have a full set of 20 milk teeth by the time they are three years old.
At the age of five or six, these teeth are pushed out by permanent teeth growing behind the milk teeth.
By the age of 14, most children have lost all their milk teeth and have a full set of 28 permanent teeth.
About around age 20, four more wisdom teeth usually grow in at the back of the mouth.
They complete the adult set of 32 teeth.
