By 10, the size of your face is closer to adult size, and so the bigger adult teeth start to be able to fit. Each set of teeth is divided into different tooth types based on shape and, therefore, each tooth is unique.
The DNA only has instructions for two sets of teeth containing each unique tooth and no more. Due to these instructions, both sets of teeth grow when they are supposed to. However, there are no instructions for extra permanent teeth beyond the 32 total permanent teeth.
The first to emerge are generally the incisors — these are the front, flat edged teeth used for biting and there are eight in all: four on the top and four on the bottom. Next come the canines, which are your more pointed teeth.
There are four in total and they bookend the incisors. The final eight teeth follow and should all be developed by the age of two years old, give or take a few months. These teeth are premolars with larger uneven surfaces, which we need for chewing, and complete our first set of 20 teeth, ten on top and ten on bottom. Milk teeth are only temporary and will be replaced by a new set of adult teeth, which begin to emerge around the age of six.

The different types of teeth Incisors are used for chopping and cutting food into small chunks, these are your front teeth and you have 4 on the bottom and 4 on the top.
Canine teeth help you to tear chewy food such as meat. You have 2 of these in the top jaw and 2 in the bottom jaw and they are positioned next to your incisors. Premolars are positioned next to your canine teeth. A full set of adult teeth will normally contain eight premolars with 4 on the top and 4 on the bottom row of teeth. We rely on these teeth for grinding and crushing chunks of food. These teeth are bigger and wider with a flat surface area on the bottom unlike your narrow and sharp front teeth.
