Dental care

Dental care
 

Probably the most common problem that affects dogs' mouths is gum disease. Starting silently with no obvious signs or symptoms, it advances quickly, causing chronic pain, eroded gums, missing teeth, even bone loss - a fate hardly fair to your four-legged friend. In fact gum disease is so common, studies show over 80% of dogs suffer a stage of gum disease before they are three years old.

What causes gum disease?

Bacteria cause gum disease (periodontal disease). Straight after your dog eats, bacteria - along with food, saliva, and other particles - forms a sticky film called 'plaque' over oral surfaces (like tooth enamel).

Gum disease is five times more common in dogs than humans, as dogs have a more alkaline mouth, promoting plaque formation. Also, most dogs don't have their teeth brushed every day, giving plaque-forming bacteria the chance they need to multiply.

Bacteria in plaque instruct your dog's immune system to recognise them as foreign, quickly marshalling white blood cells to attack. Plaque bacteria then instruct white blood cells to release enzymes to break down gum tissue. This skirmish leads to inflamed gums, destroyed tissue, and loss of teeth, bone, and even jaw fracture; all caused by untreated gum disease.

What effects can gum disease cause?

Plaque causes inflammation (reddening) of the gums (gingivitis) which can initially be very subtle, making them more likely to bleed. Plaque not removed over time hardens, mineralising into calculus (tartar), the browny yellow hard substance on your dog's teeth, and the perfect surface for even more plaque to stick to, speeding up the whole process. Gingivitis is reversible but, if left untreated, it progresses to periodontitis.

Periodontitis is irreversible, characterised by loss of attachment for the tooth in the socket, which may lead to tooth mobility, loss of tooth, and severe infections. Bacteria may potentially enter the bloodstream every time your dog chews, causing infections much further afield in the heart, lungs and kidneys.

Effects of severe gum disease can include abnormal bad breath (halitosis) caused by periodontal disease. Imagine your own breath if you stopped brushing your teeth for a few days! Never ignore this early warning sign of disease. There are many other causes of bad breath too, so it's important to get it checked by your vet as soon as possible, rather than assume it's normal or an inevitable sign of old age

Dental disease can be painful, but most animals are extremely good at covering up the signs and will rarely stop eating. So look out for difficulty picking up food; bleeding or red gums; loose teeth; blood in saliva, water bowl or on chew toys; strange noises when eating; pawing at mouth/face; and dribbling. If in any doubt, ask your vet.

What may my vet do if my dog has a problem?

Most vets perform some degree of dentistry, with no such thing as a 'typical dental'. All cases require thorough examination of the patient, both conscious and under anaesthetic. This involves examining every tooth individually, both visually and with a special probe. Dental X-Rays are often indicated to see what's happening below the gum-line in the root/socket area. Extractions, or other treatments may be required, and most patients will require scaling and polishing of teeth to remove plaque and tartar before waking up.

Pets need general anaesthetic to have dentistry performed as what we see is literally the tip of the iceberg; disease isn't often discovered until the animal is examined asleep. Your vet's priority is also to ensure your dog doesn't feel any pain, and even scaling and polishing can cause minor discomfort, so your vet always recommend that they are safely anaesthetised.

How can I prevent gum disease?

Preventing gum disease should be a part of your routine canine care with teeth ideally brushed daily, just like ours, minimising bacteria and their by-products and helping your dog maintain a healthy mouth. Surprisingly many owners seem reluctant to brush their dog's teeth as they think their dog won't like it, but most respond well, actually enjoying this new form of attention. So ask your vet to demonstrate, introduce gradually using rewards and doggie toothpaste, and you'll be brushing in no time!

If possible, introduce teeth brushing as a puppy so he or she grows up thinking it's quite normal. Regular brushing, and at least twice yearly checks with your vet, should mean less dental disease.

Feed quality dog food, 'dental diets', or special foods that prevent plaque from hardening. If in doubt, ask your vet about what diet is best for your dog, and offer tooth friendly toys and treats as well.

Remember, many pet insurance policies don't cover dental work so it's even more important to look after your pet's teeth.
