Ulceration into sinus from caries, loss of molar, overgrown molar.
Fœtor, tenderness. Foreign body in the nose.
In cases of a diseased molar tooth in the upper jaw, food getting firmly
impacted in the hollow space, irritates the pulp in the fang and the
adjacent bone until the progress in ulceration reaches the nasal chamber
or sinuse and a nasal discharge is established. If an upper molar tooth
is lost the molar formerly opposed to it in the lower jaw grows out and
sets up the same train of symptoms. In all cases then in which nasal
gleet is associated with much fœtor and with difficulty in eating, a
careful examination of the teeth should be made. (See Diseases of the
Teeth).
