write the difference between milk teeth and permanent teeth
Answers
Answer:
Primary teeth are smaller and look whiter than permanent teeth because they have thinner enamel. Their roots are also shorter and thinner. Primary teeth are usually just 20, while there are 32 permanent adult teeth. Permanent teeth will start to appear when a child is around six years old, and the jaw is large enough.
Primary teeth, also known as our milk teeth or deciduous teeth erupts first at the age of 6 to 7 months old and would usually completely erupt by around the age of 3, in time for a child's facial bone and jaw to grow. Permanent teeth start replacing the primary teeth at about 6 to 7 years old.Primary teeth are smaller and look whiter than permanent teeth because they have thinner enamel.
