5 Warning Signs of Dental Disease in Pets

Spotting the signs of dental disease in your pet early can save them from serious pain, tooth loss, and costly interventions down the track. Unfortunately, most dogs and cats are experts at hiding discomfort — which means the warning signals are easy to miss. Knowing what to look for means you can act quickly, keeping your pet's mouth healthy and their tail wagging.

Persistent Bad Breath — More Than Just "Dog Breath"

A slightly unpleasant smell after mealtime is normal, but chronically bad breath in dogs — or cats — is one of the earliest red flags for dental trouble. That lingering odour is usually caused by bacteria thriving on plaque and tartar along the gum line.

If your dog's bad breath doesn't improve after a drink of water or persists day after day, it may indicate gingivitis or periodontal disease already taking hold beneath the surface. Don't dismiss it as "just how pets smell."

Regular dental chews and enzymatic toothpaste can help control bacteria between professional cleans. Browse our full range of dog health and wellness products for options that support daily oral hygiene.

Changes in Eating Habits

When chewing hurts, pets adapt. You might notice your dog dropping kibble from the side of their mouth, chewing on one side only, or suddenly preferring softer foods. Cats may paw at their face during meals or walk away from the bowl entirely.

Weight loss that appears gradual and unexplained is another downstream consequence. If your pet is hungry but reluctant to eat, dental pain is a likely culprit.

Keep a close eye on portion sizes and eating speed — any sudden shift is worth investigating.

Red, Swollen, or Bleeding Gums

Healthy gum tissue sits snugly against the teeth with a smooth, even colour. When dental disease sets in, gums become inflamed, appearing bright red or purplish. You may also spot blood on chew toys, in the water bowl, or on your finger after rubbing along the gum line.

Gingivitis — the earliest stage of gum disease — is reversible with prompt care. Left unchecked, it progresses to periodontitis, where the structures supporting the teeth begin to break down irreversibly.

Cats are particularly prone to a painful condition called stomatitis, which causes severe inflammation at the back of the mouth. If your feline friend is drooling excessively or seems reluctant to groom, explore our cat health product range for supportive care essentials.

Discoloured or Loose Teeth

Yellow or brown build-up along the gum line is visible tartar — mineralised plaque that standard brushing alone cannot remove. You might also notice teeth that look grey or slightly translucent, which can signal damage to the pulp inside the tooth.

Loose or missing teeth in an adult pet almost always point to advanced periodontal disease. By this stage, the bone supporting the tooth has already deteriorated significantly.

Smaller breeds and brachycephalic (flat-faced) breeds tend to be at higher risk because their teeth are more crowded, creating extra hiding spots for bacteria. Regular at-home brushing is especially important for these pets.

Behavioural Clues You Shouldn't Ignore

Dental pain doesn't always show up at the food bowl. Watch for subtler behavioural shifts: increased irritability when touched around the head, reluctance to play tug-of-war, excessive drooling, or rubbing the face against furniture and carpet.

Some pets become withdrawn or less active, which owners may mistakenly attribute to ageing. In reality, chronic mouth pain can dramatically affect quality of life, mood, and energy levels.

Nasal discharge or sneezing on one side can even indicate that a dental infection has spread to the nasal cavity — a complication more common in dogs than many owners realise.

Because the signs of pet dental disease overlap with other conditions, keeping a simple journal of behavioural changes and their frequency can be genuinely helpful when discussing concerns with a professional.

Frequently Asked Questions

How common is dental disease in pets?

Studies suggest that the majority of dogs and cats over the age of three already have some form of dental disease. Because symptoms develop gradually, many cases go unnoticed until they are quite advanced. Weekly at-home mouth checks are one of the simplest preventive steps you can take.

Can dental disease affect my pet's overall health?

Yes. Bacteria from infected gums can enter the bloodstream and may contribute to issues with the heart, kidneys, and liver over time. Maintaining good oral hygiene isn't just about fresh breath — it supports your pet's whole-body wellbeing.

What is the best way to clean my pet's teeth at home?

A pet-specific toothbrush and enzymatic toothpaste used several times a week is the gold standard. Dental chews, water additives, and prescription dental diets can complement brushing but generally shouldn't replace it. Start slowly, reward generously, and most pets will learn to tolerate — or even enjoy — the routine.
