third molars are commonly called "wisdom teeth" and may never erupt into the mouth or form at all.
if any additional teeth form, for example, fourth and fifth molars, which are rare, they are referred to as supernumerary teeth.
most teeth have identifiable features that distinguish them from others.
there are several different notation systems to refer to a specific tooth.
the three most commons systems are the FDI World Dental Federation notation, the universal numbering system, and Palmer notation method.
the FDI system is used worldwide, and the universal is used widely in the united states.
enamel is the hardest and most highly mineralized substance of the body and is one of the four major tissues which make up the tooth, along with dentin, cementum, and dental pulp.
it is normally visible and must be supported by underlying dentin.
ninety-six percent of enamel consists of mineral, with water and organic material composing the rest.
the normal color of enamel varies from light yellow to grayish white.
at the edges of teeth where there is no dentin underlying the enamel, the color sometimes has a slightly blue tone.
since enamel is semitranslucent, the color of dentin and any restorative dental material underneath the enamel strongly affects the appearance of a tooth.
