Molar

MolarA molar is a tooth located completely in the back of the dental arch. It is the most voluminous type of tooth, with four to five cusps, and two to four roots. The major role of molars is to finalize the grinding of foods before swallowing.

There are eight molars in primary teeth, four on top (two on each side) and four at the bottom. The primary molars are replaced by the premolar adult teeth.

In permanent teeth, there are twelve molars, six on top (three on each side) and six at the bottom, including the four wisdom teeth. Permanent molars, without counting wisdom teeth, are very important to chew foods. If they are removed and are not replaced, there may be serious long term consequences in the balance of the occlusion of teeth, and in oral health in general.
