7 Signs of Dental Disease in Dogs (and What You Should Do Next)

Dental disease is one of the most common health problems in dogs, and many dogs still eat normally even when their mouth is sore. Spotting signs early can save your dog pain and reduce future treatment costs.

Quick answer

If your dog has ongoing bad breath, red or bleeding gums, visible tartar, face rubbing, or chewing discomfort, book a vet dental check. Daily brushing with dog-safe toothpaste remains the strongest home prevention step.

1) Persistent bad breath

Long-lasting strong odour can be an early sign of plaque and gum inflammation.

2) Red, swollen, or bleeding gums

Healthy gums are usually firm and pink. Redness or bleeding needs attention.

3) Yellow or brown tartar build-up

Tartar around the gumline can progress into deeper periodontal disease.

4) Difficulty chewing or dropping food

Chewing hesitation or dropping kibble can indicate oral discomfort.

5) Pawing at the mouth or face rubbing

Repeated face rubbing is a common discomfort signal, especially with other symptoms.

6) Excess drooling

A noticeable drooling change can suggest oral irritation or pain.

7) Reduced appetite or behaviour change

Dental pain may show up as reduced appetite, irritability, or lower activity.

What to do next (simple action plan)

1. Book a vet check if symptoms are persistent or painful.
2. Start daily brushing with dog-safe toothpaste and a soft brush.
3. Use VOHC-accepted products as support (not a brushing replacement).
4. Avoid human toothpaste and very hard chew objects.
