the British Medical Journal) that even where the
permanent teeth are poorly positioned and im-
perféctly calcified in their original structure, vita-
min D powerfully aids in the corrective process. It
also tends to diminish the spread of existing cari-
ous points and to check the initiation of new ones.*

Fewer Dead Teeth in Adults

Teeth are living tissues, and are now known
to be responsive to certain dietary influences
throughout life. Chief of these is the presence or
absence of sufficient calcifying vitamin D.

A most important effect of vitamin D in the
diet is in relation to Nature’s last line of tooth
defense, the secondary dentine. By stimulating
its development, vitamin D tends to reduce the
danger of tooth devitalization through pulp
exposure.

The treatment of malposed and carious teeth
is also aided by the increased calcium absorption
which this vitamin helps bring about.

Important as a Preventive Measure

A new era in dentistry is approaching, in which
the prevention of dental faults will assume equal
importance with their correction.

The newly discovered importance of vitamin
D has given tremendous impetus to this new
attitude. Its new availability in Fleischmann’s
Yeast—a corrective food already widely known
for its other benefits—is a boon that dentists
have not failed to appreciate.

The routine recommendation of Fleischmann’s
Yeast, not only to pregnant or nursing mothers,
but to a// your patients, both adult and juvenile,
will help assure more lasting and satisfying re-
sults for your work.

*Since Fleischmann’s Yeast may be too laxative for
very young children, it should be given to children
under 5 only under direct medical supervision.
