Thanks for using Petco Pet Education Center, formerly Petcoach! Based on the swelling's location, this is possibly due to a tooth root abscess. This is something your veterinarian could check for on an examination and treat if confirmed. This is something that is treated with local therapy including drainage, debridement and antibiotics. Good luck and have a great day!

    This typically happens when there is a tooth root abscess. Skipper needs to have his mouth examined by a veterinarian and might need a dental cleaning/removal of the affected tooth and prescription antibiotics specific for tooth problems.

    This swelling is from an upper molar tooth root abscess. I recommend a veterinary exam and to start antibiotics. Dogs who chew bones sometimes break their teeth exposing the root and these get infected. The antibioitcs improve the infection, swelling and pain, but usually to cure this the infected tooth will need to be extracted.

I have a 12-year-old Akita husky, and yesterday morning the side of her face swelled. Not the whole face, seemed concentrated to a small area, just above her teeth. The gums don’t look swollen, and it’s not too sensitive to touch, but I’m wondering i
Thank you for submitting your question regarding Kona. I recommend that she sees her veterinarian. While there can be a variety of reasons for swelling on the face, a tooth root abscess is most common. The roots of her molars and premolars are very large and extend upwards. A swelling below the eye is frequently seen with an infection of one of these roots. The veterinarian will examine her and determine if this is likely. If so, she will need to go under anesthesia. X-rays will be taken of her mouth to confirm an infected tooth and then it would likely be extracted. I hope this information helps!

My dogs face has swelled up very large over night, we live very far from a vet. What might it be? and what should I do about it? it isnt bothering him too much he is still eating and drinking.
I am suspicious that he has An abscess (infection). In that location it could be from a tooth, or some sort of trauma or migrating foreign object. I would highly encourage you to have him evaluated by a veterinarian soon. This likely needs antibiotics, and possibly surgery as well. In the meantime I would warm compress the area several times a day. This may encourage the abscess to drain which is what we want. Best of luck and I hope he improves soon.

3 year old boxer mix with swelling to left side of face ... about size of a walnut over last 4 days ... not hot to touch ... dog is acting normal
It is possible that Stella may have a tooth root abscess, a cyst, granuloma, benign or malignant mass, among other causes. I'm glad to hear that she is acting normally, but she should be examined by her vet to address the underlying cause. If she is diagnosed with a tooth root abscess, her vet will be able to discuss a dental extraction and antibiotics with you. Otherwise, a fine needle aspirate (FNA) can be performed to evaluate the type of cells present in this growing lesion to aid in determining the underlying cause.

my dog has swelling below eye. It broke open once and and scabed over. Scab came off and now swelling again under neath eye
Swelling directly under the eye is often an indication of a tooth root abscess. This occurs when there is severe dental disease and the tooth root becomes infected and created the pus pocket. Treatment for this is a dental cleaning with an extraction of the affected tooth. I would recommend a trip to your vet to check out the mouth and see if this is the problem. I hope this helps. Thanks for using Boop by Petco. Best of luck.

It feels hard, on the side of face. No visible color change and no pain when touched. About 1.5 inches on size. Any ideas?
I'm not sure if you tried to attach photos, but if so, nothing came through so you might want to try again. A swelling on the side of the face could be a few things depending on the location. It could be an abscess from a wound or bad tooth, an enlarged lymph node, an insect sting, or a tumor. Your veterinarian can perform a fine needle aspirate, where cells are collected with a needle and examined under a microscope. By identifying the type of cells, your veterinarian can make a diagnosis and start appropriate treatment. Thanks for using Boop by Petco.

My Australian cattle dog, Apollo, age 1.5 has a swollen spot on the right side of his muzzle. Swelling does not include teeth and gums or eye socket. Seems firm to the touch not squishy. Need help indentifying..
Hi. That is definitely some severe swelling. Due to its location and presentation, I would be very concerned about a tooth root abscess. These can occur even if the crown of the tooth appears normal. It takes an x-ray to fully diagnose it. Other possible causes of swelling like this in a young dog could include a bite from insect or spider, injury, trauma, or infection. I recommend getting him to your veterinarian to be checked out tomorrow.

My dog has a ball like swelling on the right side of her face
Swelling can be caused by trauma or infection. If she hasn't been hit or hurt herself on that side, it could be an abscess/infection. She will need to be physically examined by your veterinarian to diagnose the exact cause. Trauma may be managed with anti-inflammatory and pain medication. If it is infection, the underlying cause will need to be determined and treated for resolution.

One side of my dogs mouth/muzzle is swollen. I just noticed it today, so it is new. It appears sensitive to touch. I have tried looking in her mouth as was as inspecting the exterior of her mouth and did not notice anything out of the ordinary.
I would recommend taking Rozzi to a veterinarian. I would call yours in the morning. It is difficult to say definitively what is going on but from the pictures it looks like a potential tooth root abscess. A tooth root abscess can appear as one side of the face or mouth is swollen. The way to treat this is antibiotics, pain meds and pulling the affected tooth. If the swelling gets worse overnight then I recommend an emergency veterinarian for a possible allergic reaction. I hope Rozzi feels better soon and thank you for using Boop by Petco.

Hi. This sounds very suspicious of a tooth root abscess. A tooth root abscess is a severe infection that develops around the root of a tooth usually occurring from a broken or traumatized tooth. They form when bacteria enter the exposed root canal of the tooth. In dogs, this most often occurs when the tooth breaks from chewing on a bone, antler, ice cubes, cow hoof, or hard nylon toys exposing the tissues that lie beneath the enamel. A tooth root abscess may also develop in association with periodontal disease, an infection of the tissues surrounding the tooth. It presents most commonly as a swelling under the eye. I would recommend getting a full exam and plan a dental cleaning with your veterinarian to further assess.
