What this symptom means clinically

Tooth pain occurs when receptors in the tooth or supporting tissues, such as pulp or periodontal tissue, are activated by irritation or damage and carried through the trigeminal nerve. Infection, inflammation, fracture, or exposed root can cause pain with touch or chewing.

🐱 In cats

Cats often have tooth resorptive lesions and hide pain, so signs may be subtle.

🐶 In dogs

Dogs commonly have periodontal inflammation related to periodontal disease and tartar, with eating changes or chewing on one side.

Clinical signs you can observe

Check whether your pet shows any of the signs below. If several apply, seek veterinary care promptly.

Record the date, time, and context when tooth pain was first noticed.
Measure or estimate the affected area or vital value when applicable, and write down the exact value and unit.
Take clear photos or short videos from the same angle and label the date and time.
Observe whether tooth pain is intermittent, persistent, improving, or worsening, and record duration.
Record related behavior changes such as appetite, activity, grooming, pain response, or avoidance of touch.
Compare left and right sides or resting and activity states when relevant, and record asymmetry or changes.
