Illustrations of "Tooth Terminology":

In the photos below, some of the terms used to describe the attributes of teeth are defined and illustrated:

Some examples of "unique attributes":

Enamel Mottling

Enamel Mottling.

Enamel Mottling occurs when different locations on the tooth are replaced by minerals with different chemical compositions (colors). It may also be caused when minerals (colors) are removed by "leaching" in an uneven pattern. Occasionally the mottling is in the layer beneath a semi-transparent enamel. When this occurs, the top layers of the enamel refract light and the colors appear to "move around" the tooth with changing light conditions.

Chatoyance a.k.a. "cat-eye"

Chatoyance a.k.a. "cat-eye"

Chatoyance, "cat-eye": occurs when the outside of the tooth enamel reflects (or refracts) light in a different manner than the inside of the blade. Just by moving the tooth in the light, the inside may be darker than the outside, then the reverse occurs. When the outside is darker than the inside, the tooth reflects light like a "cat's eye".

"Fanged" Teeth:

Pathological Folding.

Fanged teeth: are recurved to the outside of the mouth (I don't get it either. Most modern fish with small teeth are recurved in so that struggling prey is forced into the mouth.Pathological folding: occurs for various reasons (disease, injury, et. cet.) but most commonly when the tooth grows in close proximity to and is "rubbing" on the adjacent tooth. It is a unique attribute which adds value to the tooth.
