Most people only think about what is inside their mouth when they are planning what they want to eat.  Of course, its not like the inside of your mouth is very complicated, right? I mean, after all, you just have a set of 32 teeth and a tongue!  Well, did you know that there are five different types of teeth which all serve different functions in your mouth?


The first two teeth that you get are the front-and-center incisors.  First emerging from the gums at around six months of age, eventually you grow four on the top and four on the bottom—all in the front—for a total of eight.  These teeth are long and flat, designed to help you break down simple foods. These are also typically the first teeth you lose—around age 8—so you can make room for your adult teeth.


Outside the four incisors on the top and four incisors on the bottom, the canines should emerge around 18 months.  This set of four teeth, eventually, resemble “fangs” (like that of a dog, hence the name); the pair on the top tend to grow in before the pair on the bottom but, oddly, they replace themselves in the opposite order.


You may have also heard of these as “bicuspids,” the premolars grow in to improve your ability to grind and chew.  These are the wide and flat teeth in the back of your mouth which grow in pairs, too, but not side by side like the other teeth.  Premolars grow in top and bottom on one side and then top and bottom on the other side, to the rear of the canines.


By the end of the first year, the next set of primary molars should grow in.  Also called “deciduous” molars, the primary molars should start to also grow in pairs to eventually have four on the top and four on the bottom.  The first set of permanent molars, though, should grow in at around the age of 6, with the set of secondary molars growing around the age of 11.


You may know these better as “wisdom teeth” this is the final pair of teeth that grow in the very back of the jaw.  Some people never get them while some need to have them removed by an  professional (because they grow in a way that impacts the other teeth, causing pain).
