5 Signs of Dental Disease in Pets That Most Owners Miss

Most pet owners don’t realize their dog or cat has dental disease until it’s already advanced. By some estimates, over 80 percent of dogs and 70 percent of cats show signs of dental problems by age three. The tricky part is that pets are remarkably good at hiding mouth pain.

At Dunedin Animal Medical Center, we see dental disease every single day. Here are five signs that something might be going on in your pet’s mouth — even if they seem perfectly fine.

Bad Breath That Won’t Go Away

A little “dog breath” after eating is normal. Persistent bad breath is not. If your dog or cat has breath that makes you turn away, that smell is almost always caused by bacteria building up along the gumline. That bacteria doesn’t just stay in the mouth — it can enter the bloodstream and affect the heart, kidneys, and liver over time.

If the smell has been getting worse over weeks or months, it’s worth scheduling a dental exam rather than just switching to a different treat.

Dropping Food or Chewing on One Side

Watch your pet eat. A dog that suddenly starts dropping kibble, tilting their head while chewing, or only chewing on one side of the mouth may be dealing with a cracked tooth, an abscess, or inflamed gums. Cats sometimes stop eating dry food altogether and only accept wet food — not because they’re being picky, but because chewing hurts.

This is one of those signs that gets blamed on “getting older” when it’s actually a treatable dental problem.

Red, Swollen, or Bleeding Gums

Healthy gums should be pink and firm. If you lift your pet’s lip and see redness along the gumline, swelling, or gums that bleed when touched, that’s gingivitis — the early stage of periodontal disease. Caught early, gingivitis is reversible with a professional cleaning. Left alone, it progresses to periodontitis, which destroys the bone and tissue supporting the teeth.

Even if your pet doesn’t seem bothered, inflamed gums are actively causing damage. In North Pinellas County’s warm, humid climate, bacterial growth can be especially aggressive, making regular dental checkups even more important.

Pawing at the Face or Rubbing Against Furniture

When a pet repeatedly paws at their mouth, rubs their face along the carpet, or drools more than usual, they’re often trying to relieve oral discomfort. Some owners mistake this for allergies or a skin issue. While those are possibilities, a quick look inside the mouth can rule out dental pain as the cause.

Cats in particular may start hiding more or become less social when they’re dealing with mouth pain. A personality change in a cat — less playful, more withdrawn — can sometimes trace back to a painful tooth.

Visible Tartar Buildup or Loose Teeth

If you can see yellowish-brown buildup on your pet’s teeth, especially along the back molars, that’s tartar. Unlike plaque, tartar can’t be brushed away at home. It needs to be removed with professional scaling under anesthesia.

Loose teeth are a sign that periodontal disease has already progressed significantly. The supporting structures around the tooth have broken down. At this stage, extraction is usually the kindest option — a pet with a painful loose tooth feels immediate relief once it’s removed.

What You Can Do Right Now

Start by lifting your pet’s lips and looking at their teeth and gums. You don’t need to be an expert — you’re just looking for anything that seems off. Red gums, brown buildup, a broken tooth, a bad smell.

Then, schedule a dental exam. At Dunedin Animal Medical Center, we assess your pet’s oral health and recommend next steps based on what we find — whether that’s a professional cleaning, extractions, or just a plan for at-home care going forward.

Dental disease is one of the most common and most undertreated conditions in pets. The good news is that catching it early makes treatment simpler, less expensive, and much easier on your pet.
