Tooth structure

Enamel: is the most resistant structure and the most mineralized tissue in the body, but can be damaged if teeth are not cared for properly.
Dentin: the layer below the tooth enamel. Dentin is a connective tissue without blood vessels (avascular), mineralized, forming tooth, supports it and compensates for the weakness of the enamel.
Dental pulp: the tooth internal structure, formed by loose connective tissue (composed of cells, fibers and ground substance) vascularized and innervated and thick.

Knowing the teeth by name

According to its position in the mouth and their job function, the teeth are classified into incisors, canines, premolars and molars, totaling between 28 and 32 teeth. This variation in the amount due to the presence of wisdom teeth (last molars that appear between 17 and 21 years), that may or may not be born.
Incisors: these are the 8 front teeth (4 teeth in the jaw and another 4 in the maxilla) sharp chisel-shaped (four upper, four lower) occupying the front of the dental arch and are the first to come into contact with food (for the cut).
Canines: there are four dogs – two in the jaw and two in the jaw. Canines make up the arch of omnivores and carnivores, are situated behind the incisors. The teeth have sharp points that serve to tear foods.
