No, we are not talking about Hollywood
Smiles for pets. Orthodontic care in pets focuses
on relieving teeth that are positioned incorrectly and causing
pain. Orthodontic care in pets can take many forms, including
acrylic appliances, brackets and elastics, and simple extractions.
One common form of orthodontic
care, called “interceptive orthodontics”, is employed
when deciduous (baby) teeth are positioned incorrectly, or
fail to be shed as the adult teeth erupt. (See
the FAQ on Double Teeth) The presence of more
than one tooth in the same place at the same time can lead
to a painful malpositioning of the adult teeth. In some cases,
early extraction of the baby teeth will allow the adult tooth
to come in normally. To correct the problem, the entire root
structure must be extracted. Some breeders will simply clip
the baby teeth off with nail trimmers, which is painful, often
leads to infection under the gum line, and rarely helps the
permanent teeth position themselves normally. This practice
is not humane, and is discouraged.
CASE
#1
Extraction
of malpositioned deciduous (baby) teeth.
 |
 |
| Eight
week old puppy with the lower incisors incorrectly placed
in front of the upper incisors (underbite). |
Ulcerated
areas where the upper incisors are hitting the lower gums. |
 |
All
the deciduous (baby) incisors were extracted. The white
lines separate the visible part of the tooth from the
root. Note how much longer the roots are by comparison.
The entire root must be extracted. |
CASE
#2 Retained
baby teeth causing adult tooth to be pushed out of normal position.
 |
 |
| Retained
baby canine tooth (long arrow) is pushing the adult tooth
(short arrow) to the right, which is crowding the other
teeth in this area. The baby tooth was extracted |
Retained
lower canine teeth (short arrows) are causing the lower
adult canine teeth to be displaced toward the inside (longer
arrows) of the mouth. |
At times, the lower canine teeth are positioned
so that they place painful pressure on the roof of the mouth,
leading to ulcers or even the formation of a hole into the nasal
passages. In some cases, this can be corrected with an acrylic
appliance placed on the upper teeth, which gently re-directs
the offending teeth into normal alignment.
CASE
#3
Correction of base narrow lower canine teeth traumatizing the
roof of the mouth.
One additional area where orthodontics
is of benefit is in cases where the teeth are hitting one
another abnormally. This can lead to fractures or loss of
supporting structures of the teeth. Treatment can range from
extraction to simple reduction of the tooth size, to active
orthodontic repositioning.
Orthodontic problems require
experience to evaluate and treat properly. If you suspect
an orthodontic problem in your pet, consult with a veterinarian
familiar with these conditions.
