A dog repeatedly pawing at their mouth or face is one of the clearer signs that something is bothering them. Unlike some dog behaviors that are ambiguous, this one usually means: something is uncomfortable in or around my head. The question is what — and that answer ranges from a piece of food stuck between teeth to a dental abscess to an ear infection to an allergic reaction.
This guide walks through every major cause of dogs pawing at their mouth or face, how to distinguish between them, and when a vet visit is necessary.
Dental Pain or Oral Discomfort
Dental disease and oral pain are among the most common reasons dogs paw at their mouths — and the most often missed by owners. A dog can’t say “my tooth hurts” so they gesture. Pawing at one side of the face, rubbing the muzzle along the ground, or repeatedly scratching at the jaw are all classic expressions of oral discomfort.
Specific oral causes that trigger pawing:
- Tooth root abscess — pus-forming infection at the tooth root, often causing one-sided facial swelling below the eye. The dog may paw specifically at that side.
- Fractured or broken tooth — exposed pulp is intensely painful, especially to air and temperature changes.
- Loose tooth — particularly in adult dogs, where a loose tooth indicates underlying disease rather than normal shedding.
- Severe gum disease — advanced periodontitis causes painful, inflamed gum tissue.
- Foreign object stuck — a bone fragment, stick shard, or piece of toy lodged between teeth or under the tongue.
- Oral tumor — growths in the mouth can cause chronic irritation that a dog responds to by pawing.
Signs that pawing is dental-related:
- Pawing specifically at one side of the face
- Reluctance to eat hard food or chew toys
- Bad breath that has worsened recently
- Visible swelling on the cheek or below the eye
- Red, swollen, or bleeding gums on inspection
If dental disease is suspected, a full oral exam is needed — ideally with dental X-rays under sedation, since most dental problems are below the gumline and invisible to the naked eye. See our guide: Signs Your Dog Needs a Professional Dental Cleaning.
Foreign Object in the Mouth
A bone splinter, stick fragment, grass seed, or toy piece lodged between teeth or under the tongue can cause a dog to paw urgently and repeatedly at the mouth. This type of pawing is typically acute — it starts suddenly while or just after eating or chewing something — and is often paired with lip licking, yawning, gagging, or attempts to rub the face against objects.
How to check: gently open your dog’s mouth and look carefully. Check between the teeth, under the tongue, and along the roof of the mouth. If you can see the object and safely grasp it, you can remove it. If it’s deep in the throat, not visible, or your dog won’t let you check, go to the vet — attempting to blindly probe can push the object deeper or cause injury.
Ear Problems
This one surprises owners: ear infections, ear mites, or ear polyps can cause dogs to paw at their face even when there’s no obvious ear discharge. The external ear canal and the jaw area share nerve pathways, and pain from the ear can manifest as scratching or pawing around the cheek, jaw, or base of the ear.
Signs that ear problems are the cause:
- Shaking the head along with or instead of pawing
- Scratching at the ear itself (not just the face)
- Odor from the ear canal
- Discharge, redness, or dark debris inside the ear
- Head tilting
Ear infections in dogs are very common and very treatable — but they don’t resolve on their own. A vet will look inside the ear canal with an otoscope and prescribe appropriate ear drops or oral medication depending on whether it’s bacterial, yeast, or mite-related.
Eye Problems
Corneal scratches, conjunctivitis, foreign bodies under the eyelid, or glaucoma can cause significant eye discomfort. Dogs experiencing eye pain will often paw at the affected eye and the surrounding area. Look for: squinting, redness in the white of the eye, discharge, cloudiness, or asymmetric pupil size. Eye problems can worsen quickly — contact your vet the same day.
Allergic Reactions or Skin Irritation
Allergies — whether food, environmental, or contact — frequently cause facial itching in dogs. The muzzle, around the mouth, and between the toes are classic allergy “hot spots.” If your dog is pawing at their face and also licking their paws, rubbing their face on carpets, or has red/itchy skin elsewhere, allergies are high on the list.
Specific face and mouth triggers:
- Reaction to a food your dog recently ate (especially new treats or table scraps)
- Contact with grass, plants, or ground-level allergens
- Reaction to a grooming product (shampoo, conditioner, nose balm)
- Insect bite on the muzzle or lip
Nausea or Gastrointestinal Upset
A nauseous dog may repeatedly lick their lips and paw at their mouth as part of the pre-vomiting or nausea response. If your dog is pawing at the mouth in combination with drooling, swallowing repeatedly, yawning excessively, or retching, GI upset is the likely cause. This often resolves on its own, but persistent nausea, vomiting, or abdominal pain warrants a vet call.
Anxiety or Compulsive Behavior
Some dogs develop repetitive face or mouth pawing as a self-soothing or compulsive behavior, especially if they are anxious or under-stimulated. This is more likely if the pawing happens in specific situations (when left alone, during loud noises) and there’s no obvious physical trigger. Behavioral pawing can be difficult to distinguish from pain-motivated pawing; when in doubt, rule out physical causes first.
When to See the Vet
See a vet promptly (within 24 hours) if pawing is:
- Persistent — happening repeatedly over more than a day
- Paired with visible swelling, especially one-sided facial swelling
- Accompanied by bad breath, reluctance to eat, or drooling
- Following known or suspected toxin exposure
- Paired with eye squinting, redness, or discharge
- Combined with head shaking and ear odor
Go immediately if there is:
- Rapid facial swelling (possible allergic reaction or abscess)
- Difficulty breathing or swallowing
- Evidence of a stuck foreign object in the throat
- Pawing that started after possible toxin ingestion
Frequently Asked Questions
Why does my dog keep pawing at their mouth?
The most common causes are oral pain (dental disease, broken tooth, foreign object), ear problems, eye irritation, allergic reactions, or nausea. If it’s persistent — happening repeatedly over more than a day — a vet visit is warranted to rule out dental disease or another treatable cause.
Can dental disease cause a dog to paw at their face?
Yes — dental pain is one of the most common causes. A tooth abscess, broken tooth, loose tooth, or severe gum disease can all cause a dog to repeatedly paw at the affected side of the face. If pawing is one-sided, involves swelling, or comes with bad breath, a dental exam should be the first priority.
My dog is pawing at their mouth after eating — what does it mean?
Pawing immediately after eating suggests a foreign object stuck between teeth or in the throat, a food allergy or sensitivity, or nausea from what they ate. Check the mouth for stuck debris. If the pawing continues beyond 15–20 minutes or is paired with drooling or gagging, call your vet.
How do I check my dog’s mouth for a stuck object?
Have someone hold your dog gently while you open the mouth. Use good lighting — a phone flashlight helps. Check between the teeth (especially the back molars), under the tongue, and along the roof of the mouth. If you can see and safely grasp the object with two fingers, you can carefully remove it. If you can’t see anything, if the object is deep in the throat, or if your dog is distressed, go to a vet rather than probing blindly.
Is a dog pawing at their face an emergency?
It depends. Sudden-onset pawing after suspected toxin exposure, pawing with breathing difficulty, or rapid facial swelling are emergencies. Persistent pawing with bad breath and face swelling (possible abscess) should be seen the same day. Intermittent pawing with no other symptoms can be monitored briefly, but if it continues beyond 24 hours, a vet visit is wise.
