Everyone can grow two sets of teeth in their lifetime. The teeth that grow out from the moment you are born are called deciduous teeth. Starting from the age of 6 or 7, students begin to change their teeth and grow a new type of teeth called permanent teeth. If the permanent teeth are broken or lost, new teeth will not grow back, so we all need to protect our teeth.

Changing teeth is a sign of growth! All your permanent teeth will come out before you are about 14 years old. There are 28 teeth in total! Some students will grow up to 32! How are you looking forward to it?
