By the age of three, the baby teeth will have all come out. They start ripening from the age of six. As a result, permanent teeth begin to appear in their place.
By the age of six, permanent teeth begin to erupt in place of the baby teeth. As they begin to grow, the roots of the molars erode, causing them to lose their ability to withstand the pressure of the new tooth rising. That’s why they fall off.
It is said that there are 32 permanent teeth and only 20 molars. The jaw does not grow then as it does not require hard chewing at the age of the molars. The jawbones also grow when you eat solid foods. That’s 32 permanent teeth.
