Bacteria, Plaque and Tartar in Dogs

Dental problems are a common complaint at veterinary clinics. Along with chipped or broken teeth, dogs can also develop painful cavities, periodontal disease, and hard deposits of plaque and tartar on the teeth. These disorders of the mouth not only are started by bacteria, but they usually harbor bacteria as well, giving them ideal environments in which to multiply. The bacteria are then able to spread to other parts of the body as well. Your pet’s dental health should be evaluated by a veterinarian annually.

An overabundance of bacterial growth and accumulation on and around the teeth can cause dental disorders such as gingivitis, periodontal disease, and infected abscesses.

Plaque is composed of polysaccharides and glycoproteins colonized by several types of bacteria which are commonly found in the mouth. If not removed from the teeth these deposits harden and form ideal breeding places for more bacteria. As these bacteria invade the gums and teeth of your animal they can cause inflammation and bleeding of the gums, bad breath, weakened tooth and bone structure, and dangerous pockets of infection. Serious cases of dental infection can extend out into other parts of the body, causing infections in vital organs such as the heart, kidneys, and liver.

When a dog is brought into the clinic with a complaint of malodorous breath or other symptoms indicating oral disease, your veterinarian will examine the canine’s mouth for obvious signs of inflammation, bleeding, or pus. General blood tests such as a (CBC) complete blood count and biochemical profile will also be taken to gauge the patient’s overall health and check for any toxins or imbalances. A more thorough examination of the teeth and gums themselves are usually undertaken after the animal is fully sedated so that the veterinarian can probe the between the teeth and gums to check for infection without causing the dog additional discomfort. Gentle finger pressure is used on each tooth to evaluate if there is any looseness or detachment of the teeth themselves. X-ray imaging may be used to assess the health of the structures below the gumline if there is evidence of underlying tooth or bone damage.

Moderate to severe dental infections will most likely require that your pet be sedated or placed under general anesthesia. The veterinarian or technician handling your pet’s disorder will start by removing as much of the tartar and plaque buildup as possible. She will scale and clean each of the teeth, both above and below the gum line while assessing the extent of both infection and inflammation. In severe cases, technicians have additional surgical techniques that can assist in the eradication of the infection. In some cases, bone replacement and augmentation can help a dog retain loosened teeth, and the use of the dental flap technique allows for the brief exposure of the root of the tooth and facilitates deep pocket cleaning and difficult tooth extractions. Oral antibiotics are often administered as a matter of course after dental cleanings in canines, to prevent any systemic infections due to the disruption of a vast number of bacteria during the cleaning itself.

Bacterial buildup in the mouth can be avoided by regular dental health care starting at around six months of age. Regular brushing of your canine’s teeth is advised to prevent tartar from forming, and toys and treats designed to dislodge plaque from your dog’s teeth can be very helpful in between brushings. Most veterinarians advise that you bring your pet in for a full dental cleaning approximately once a year. When your dog returns home from their regular dental cleaning, they may still be somewhat confused and disoriented due to the influence of the anesthesia and a calm, quiet environment will help speed recovery.
