What are different types of teeth?
For one thing, they are inherently unique to all of us since being born. For each person, teeth grow differently and at an average of four micrometers per day. That’s why identities can be discovered through teeth. They can give a rough age estimate, distinguish ethnic backgrounds and be traced back to particular individuals. Wearing out teeth also depends on how old you are but this varies as well. Different individual habits and lifestyles can also be better understood by the state of the teeth. We recently caught up with the dentists at to discuss how they approach custom patient care. Below is a summary of their research and approach to the problem of tailoring oral care with specific types of teeth and tooth related issues.
Though every tooth has a name, there can be multiples of the same types of teeth. In a full set of teeth there are two upper central incisors and upper lateral incisors. Every tooth in the mouth has its own designation and many different ways to be labeled. But there are some popular methods by which they can individually be identified. Popular methods can include through the FDI (Federation of Dentaire Internationale), The Palmer Method and The Universal System.
Types of Teeth and What They Do
Incisors are the front and center teeth, usually number eight. They are generally distributed with four on bottom and four on the top. You take bites of food with these teeth specifically. Usually the first teeth to erupt after being born, they compose the first set of teeth at 6 months and make up the adult teeth that begin to come in at age 7 or 8.
Second are the Canines. There are usually four in number and they are the next teeth that develop. They are also the sharpest of your teeth, mainly used for tearing or ripping foods apart, such as steak. These canines usually erupt between age 16 and 20 months, with uppers coming in before lower teeth. However, when the adult teeth or permanent teeth come in, lower canines appear around age 9 and the top canines coming about 12 years of age.
Third are Premolars, which are used primarily for chewing. Typically there are four premolars on both sides of the mouth, with two upper and two lower. Appearing at around age 10, first premolars come in, followed by the second set.
Fourth are Molars, also used for chewing and grinding. Molars come in at almost 15 months of age. These molars (also called deciduous molars) eventually will have permanent premolars replacing them (four top, four bottom). The permanent molars come in behind the premolars and the primary teeth. Erupting around the age of 6 years, primary molars eventually fall out, replaced by secondary molars between ages 11 and 13.
Lastly, there are Third Molars which are commonly referred to as wisdom teeth. Last to develop, these teeth erupt at the ripe old age of 18 to 20. Some never develop these third molars. Those who do however, sometimes have to have them removed because of overcrowding.
