Heister in 1743 wrote a dissertation on extraoral teeth.

The following is a recent quotation:-- "In the Norsk Magazin fur Laegevidenskaben, January, 1895, it is reported that Dr.Dave, at a meeting of the Medical Society in Christiania, showed a tooth removed from the nose of a woman aged fifty-three.

The patient had consulted him for ear-trouble, and the tooth was found accidentally during the routine examination.

It was easily removed, having been situated in a small depression at the junction of the floor and external wall of the nasal cavity, 22 mm.
from the external nares.

This patient had all her teeth; they were placed somewhat far from each other.
