To use the charts showing dental age characters, you must have a clear view of the cheek teeth on at least one side of the lower jaw. The mouth must be opened as far as possible. A tire tool or other type of pry bar is usually needed. Cutting the cheek muscles provides a clear view of the cheek teeth after the mouth is opened. If the cheek muscles cannot be cut, as on a trophy buck, a flashlight will help in seeing the cheek teeth.
Fawns have less than six teeth.
They fall, therefore, into the four-seven months age class. Fawns less than four months will have only three cheek teeth, and fawns over seven months will have five cheek teeth. The front teeth of deer are not important in determining age because all four pairs are replaced by eleven months of age. The other three pairs of incisors are replaced at 9-11 months. If there are six cheek teeth, look closely at the third tooth.
