Dental Caries
We used to think that dogs did not get
cavities. Now we know differently.
In an article published in the Journal of
Veterinary Dentistry (15(2), 1998) I pointed
out that caries (the proper latin term for
bacterial decay of dental hard tissues) does
in fact occur in dogs. I also noted that early
detection of lesions, or anatomic defects
predisposed to the development of lesion
allows for restorative procedures to prevent
serious decay and loss of the tooth.
Since publishing that article, I have been
looking for caries more aggressively and am
finding them more often that suggested in
the published data. Is the incidence of caries
on the rise or am I just finding more of them
because I am looking for them? I do not
know, but I do know that they occur and we
should all be on the look out for them when
ever we get a chance. Below is a reprint of
the chapter from my book, Understanding
Veterinary Dentistry, on the subject.
“Cavities” is the common term for dental
decay, more properly know as caries, which
is Latin for rottenness. Caries is one of the
most common diseases in man. Caries has
been defined as “a disease of the calcified
tissues of the teeth resulting from the action
of micro-organisms on carbohydrates,
characterized by decalcification of the
inorganic portions of the tooth and
accompanied or followed by disintegration
of the organic portion”.
Caries then, is a bacterial decay of the tooth
structure brought about by the release of
acids from oral bacteria fermenting
carbohydrates on the tooth surface.
Therefore, a diet high in highly refined and
easily digestible carbohydrates will favor the
development of caries. As western
civilization progressed, our diet changed to
include the types of foods that would
promote decay and so caries became a
widespread and serious concern. It is only
recently that the use of fluoride and
improved oral hygiene practices has brought
about a decline in the incidence of caries.
