The 4 Types of Teeth and How They Function 1 The 20 primary teeth are in place by age 3 and remain until around 6 years of age when they begin to fall out to make way for the permanent set of teeth. 2  Adult teeth start to grow in between 6 and 12 years of age. 3  Most adults have 32 permanent teeth. Your four canines are the next type of teeth to develop. 2  These are your sharpest teeth and are used for ripping and tearing food apart. 3  Primary canines generally appear between 16 and 20 months of age with the upper canines coming in just ahead of the lower canines.
