Detailed explanation-1: -The average child has their full set of 20 primary teeth by the age of 3 years. Between the ages of about 6 and 7 years, the primary teeth start to shed and the permanent teeth begin to come through. By the age of about 21 years, the average person has 32 permanent teeth – 16 in the upper jaw and 16 in the lower jaw.
Detailed explanation-2: -The primary set of teeth consists of 20 teeth. These are made up of: four incisors, two canines and four molars in each jaw. Incisors bite pieces of food, canines hold and tear food apart and molars grind food.
Detailed explanation-3: -Typically, children have 20 teeth, and adults have 32 teeth (28 if the wisdom teeth are removed). Remember that each one of them needs your care, even baby teeth. There are some cases where the number of teeth varies, resulting from tooth loss, tooth agenesia, or having extra teeth.
