Catching the signs of dental disease in your pet early can save them from serious pain and costly procedures down the road. Studies suggest that the majority of dogs and cats over three years old already have some form of periodontal disease — yet many owners miss the subtle clues. Knowing what to look for means you can act fast and keep your pet's mouth healthy.

1. Bad Breath That Won't Go Away

A little "dog breath" after a meal is normal, but persistent bad breath in dogs — or cats — is one of the earliest red flags of dental trouble. That foul odor is usually caused by bacteria building up along the gum line and on the surfaces of the teeth.

When plaque hardens into tartar, it creates pockets where bacteria thrive, producing sulfur compounds that cause the unmistakable smell. If your dog's bad breath lingers for more than a day or two, it's time to take a closer look inside their mouth.

Don't dismiss stinky breath in cats either. Feline dental disease often goes unnoticed because cats are experts at hiding discomfort. A quick sniff test during your daily routine can be surprisingly revealing.

2. Changes in Eating Habits

Has your pet suddenly become a picky eater? Dental pain frequently causes dogs and cats to chew on one side of the mouth, drop food mid-bite, or refuse hard kibble altogether. Some pets swallow food whole to avoid chewing.

Weight loss can follow if the problem goes unaddressed. If your normally enthusiastic eater starts turning away from the bowl, oral discomfort could be the hidden culprit.

Keeping your pet in peak condition involves more than just dental checks. Browse our full range of dog health products to make sure their overall wellness routine is covered — from parasite prevention to nutritional support.

3. Red, Swollen, or Bleeding Gums

Healthy gums should be pink and firm. If you lift your pet's lip and notice redness, puffiness, or even spots of blood, gingivitis is likely already present. Left unchecked, gingivitis progresses to periodontitis, which can destroy the bone supporting the teeth.

Look for a yellowish-brown crust on the teeth near the gum line — that's tartar. Once tartar forms, brushing alone won't remove it. Professional cleaning becomes necessary to prevent further damage.

4. Excessive Drooling or Pawing at the Mouth

Some breeds naturally drool more than others, but a sudden increase in drooling — especially if the saliva is thick, discolored, or tinged with blood — can point to dental disease in pets. Cats may drool noticeably when they have painful oral lesions such as tooth resorption.

Pawing at the face or rubbing the mouth against furniture are behavioral signs of oral pain. You might also notice your pet shaking their head or flinching when you touch the area around their jaw.

Cats are particularly prone to hiding pain, so any change in grooming habits — like a suddenly unkempt coat — could also indicate mouth discomfort. Check out our cat wellness products to support your feline's health on every front.

5. How to Protect Your Pet's Dental Health

Prevention is far easier — and cheaper — than treatment. Here are practical steps you can start today:

• Brush regularly. Use a pet-specific toothbrush and enzymatic toothpaste. Even two to three sessions per week make a meaningful difference.
• Offer dental chews. Quality dental treats help scrape plaque off teeth between brushings.
• Use a water additive. Pet-safe oral rinses added to the water bowl can reduce bacterial load in the mouth.
• Schedule routine oral exams. Regular check-ups catch problems before they escalate.
• Feed a balanced diet. Proper nutrition supports strong teeth and gum tissue from the inside out.

Staying consistent with a dental care routine — even a simple one — dramatically lowers the risk of advanced periodontal disease. Pair good oral hygiene with a solid parasite prevention plan, and your pet is set up for long-term health.

Frequently Asked Questions

At what age does dental disease usually appear in pets?

Most dogs and cats begin showing early signs of dental disease by age three. However, smaller dog breeds and certain cat breeds can develop problems even earlier. Weekly mouth checks help you catch issues regardless of your pet's age.

Can bad breath in dogs signal something other than dental disease?

Yes. While persistent bad breath in dogs is most commonly linked to oral bacteria and tartar buildup, it can occasionally indicate digestive issues or other underlying health concerns. If improving dental hygiene doesn't resolve the odor, a professional examination is a smart next step.

Is it too late to start brushing an older pet's teeth?

It's never too late. Older pets benefit greatly from a gentle brushing routine, even if they already have some tartar. Start slowly, use plenty of positive reinforcement, and gradually increase the duration of each session.
