Dental Care
Cats and Dogs
Gum disease is common in dogs and cats, probably
because of the relative softness of modern pet foods compared
to a natural diet. Accumulation of hard scale at the base of
teeth leads to gum inflammation and recession and can allow infection
to penetrate to the tooth roots themselves, causing pain, the
loss of teeth and sometimes the spread of infection in the blood
to vital organs.
Once scale (also called tartar or calculus) has
built up on teeth it can only be removed using dental instruments
or an ultrasonic scaling machine. Human dentists often need
to use a similar machine. While people will (generally!) sit
still for this, animals will not and must be anaesthetised.
Once the teeth are clean they are polished to discourage the
build up of more calculus. In severe cases dental extractions
may be necessary.
Regular toothbrushing is the best way to prevent
scale accumulation in dogs of all ages. Brushing won't shift
existing scale, but will stop it building up in puppies or in
older dogs with clean teeth, especially after a dental at the
vets. Adult dogs can be trained to accept brushing, while puppies
and kittens get used to it very easily if you start young.
If
your pet can't be persuaded to allow brushing other preventative
measures are available, including enzymatic gels, special foods
and certain rope chews for dogs.
Rabbits, Guinea Pigs, Chinchillas
Dental disease is unfortunately
all too common in the rabbit population. Certain breeds such
as Lops are particularly prone to this problem. Dental disease
in rabbits is most commonly due to 'malalignment', when the upper
and lower teeth don't quite meet perfectly. Rabbit teeth grow
continuously to allow for natural wear as the rabbit grinds up
it's fibrous diet. If the teeth don't match up they do not wear
down evenly. This can result in very long incisors which will
make eating difficult or impossible. These paired teeth are easily
inspected at the front of the mouth.
Another consequence of malalignment
which can be harder to spot can affect the grinding molars
at the back of the mouth. Uneven wear of this chinchilla's
molars has resulted in a sharp spur (upper right) which has
caused cheek ulceration. Similar spurs can occur on the inside
of the lower molars causing tongue ulcers, pain and difficulty
eating. Very similar problems are seen in rabbits. These teeth
are difficult to see and some animals require general anaesthesia
for full examination.
Signs of dental disease include:
Obviously overgrown incisors
A hungry animal unable to eat
This will progress to weight loss
Saliva dribbles down chin and
onto chest
Food may drop from side of mouth during eating
General signs
of pain - hiding, tooth grinding, character changes
Incisors can
normally be burred short without sedation in all but the most
nervous rabbits. Attention to molar spurs normally requires general
anaesthesia. In severe case incisor extraction may be an option
but does carry certain risks.
Chinchillas can be prone to similar
conditions.
Rats, hamsters, gerbils, mice and guinea pigs can
all suffer from overgrown incisors, this is a common cause of
failure to eat. |
