Whilst most cases of bad breath in dogs and cats is caused by dental disease, bad breath can be a symptom of more severe health conditions such as Diabetes Mellitus, kidney failure or liver damage. At Peakhurst Veterinary Hospital, we recommend all owners book an appointment to have their pet checked if they have malodorous breath or any other signs associated with dental disease.
If your pet has dental disease, here’s what you need to know upfront:

The main symptoms of dental disease in dogs and cats include:
Cats and small breed dogs are particularly prone to dental disease. These breeds are also often “mouth shy” so owners cannot regularly check their teeth, especially the back ones. Hence, the extent of dental disease can go undetected for long periods of time.
A healthy mouth in dogs and cats should not be persistently malodorous, should have pink gums to the tooth line, should have full length undamaged teeth and an absence of mineralised tartar.
Both plaque and tartar contribute to dental disease and breakdown of healthy oral tissue, but they are distinctly different substances.
Plaque is a biofilm which forms on teeth after eating and forms when oral bacteria, food debris and saliva combine. It is a soft, sticky substance readily removed with tooth brushing.
Tartar (or dental calculus) is a mineralised form of plaque that occurs if plaque is not removed regularly. Tartar strongly adheres to teeth and cannot be removed by brushing, requiring professional veterinary cleaning.

Dental disease is painful
Many animals do not show overt signs of pain until the dental disease is advanced despite the pain being present for extended periods of time; they mask/hide the discomfort from owners.
Dental disease damages the mouth
Dental disease in dogs and cats causes long term damage to teeth, gums and the bones of the jaw. Loss of teeth compromises your pet’s ability to eat, loose teeth cause pain and discomfort and gum loss exacerbates the potential for further tooth loss and pain.
Dental disease can cause bone infection
Teeth are embedded in the bones of the jaw and infection can spread from the mouth into these bones. Bone infection weakens bony structures and can result in further tooth loss and fracturing of the jaw. Bone infection requires long term antibiotic treatment to heal.
Dental disease can make your pet sick
Dental disease is not isolated to causing medical issues in the mouth. The bacteria involved in dental disease can become widespread throughout the body. When gums bleed, the bacteria gain entry to the bloodstream and can cause infection in other organs, notably the heart, liver and kidneys. Infection in these organs compromises function and can lead to multiple medical issues.
Dental disease is a serious condition, leading to significant health issues in affected animals. Prevention and early detection are essential for the long-term health of your pet.
Owners can proactively prevent dental disease in their pet by implementing preventative measures such as:

Any dental intervention performed on dogs or cats must be performed under general anaesthesia for the safety and welfare of the animal.
At Peakhurst, we perform pre-anaesthetic blood screening to identify any areas of concern before giving anaesthetic agents to your pet. Intravenous fluids (“a drip”) are provided to all animals undergoing dental treatment.
Once anaesthetised, all teeth are individually assessed by the veterinarian and any issues identified. The teeth are graded according to a 4-tier system and an individualised plan made for treating the teeth.
Grade 1 requires a scale and polish only.
A scale and polish involves ultrasonic scaling of all teeth to remove any accumulated plaque and thin tartar if present. Manual scaling will occur under the gum line to ensure all plaque is removed. Once the teeth have been scaled (cleaned) on all sides, a polishing paste is used and high-speed polishing of each tooth then removes any micro-abrasions on the teeth to help reduce the attachment of plaque post-dental.
Grades 2-4 will require more extensive treatment as well as a scale and polish.
At Peakhurst, we use digital dental radiography to assess teeth below the gumline to ensure the veterinarian is aware of any issues associated with the teeth deep within the jaw.
The thick cement-like tartar will be removed and the teeth examined. If any tooth roots are exposed, gum recession is noted or loose teeth are identified, tooth extraction will be needed. The surgical removal of teeth is a delicate process which may involve gums, bone and the affected tooth. Multi-rooted teeth will need to be split into individual root segments. Sutures will generally be placed and antibiotics are often given.
Animals undergoing a grade 2-4 dental procedure will be discharged from Peakhurst Veterinary Hospital with antibiotics and pain relief. Written discharge instructions will guide owners through the recovery period.

Given the complex nature of veterinary dental surgery, cost can be a factor of concern for owners. At Peakhurst Vet, we use veterinary dental bundles which provide cost effective dental treatments for pets.
The full extent of dental treatment needed cannot be fully assessed in the conscious animal. Once all tartar has been removed and the teeth fully assessed, the treatment required can be determined. For this reason, you will be given a range in your cost estimate which covers the grade of disease based on a visual inspection of your conscious pet and the next grade up in anticipation of the damage being more extensive as is often the case. Our veterinary dental bundles are price capped to assist owners with budgeting.
Dental disease is a serious and common medical condition seen in pet dogs and cats. Preventative measures can be implemented at home, but only professional veterinary dental treatment will remove tartar and restore the pet’s mouth to a healthy state once dental disease has taken hold. Maintaining a healthy mouth is a vital component of keeping your pet healthy due to the myriad of effects dental disease can have on other vital organ systems of the body.
Adult dogs have 42 teeth.
Adult cats have 30 teeth.
It is ideal for pets to maintain a full mouth of healthy teeth throughout life. However, if loose, damaged or diseased teeth are present, it is best to have the affected teeth extracted.
Dogs and cats are remarkably capable of eating after teeth have been surgically removed. Immediately post dental surgery you will be given instructions on what is appropriate to feed your pet during recovery. Long term your pet will likely return to its pre-dental procedure diet unless a more appropriate diet is identified.
Pet insurance policies differ greatly.
We strongly recommend you contact your pet insurer directly prior to the procedure if you are not sure of your coverage for dental procedures. If you are insured with a Gap Only provider, we can send the estimate to them for a pre-approval estimate of your level of coverage. We suggest this be done at least a few days before the procedure, so you are aware of your contribution prior to procedure day.
