What is Tumors of the Gums (Epulis)?
Epulis tumors are tumors located in the gum tissue near the canine’s teeth. Also known as gum boils, they originate in the tissue that connects the teeth to the bone of the jaw. Epulis tumors are generally benign, but some varieties are prone to invading nearby tissues and require removal of the growth and the surrounding tissue. This can sometimes include the removal of all or part of the jawbone. There are three generally recognized types of epulis; fibromatous, ossifying and acanthomatous.
Epulis are benign growths that originate in the tissue that connects the teeth of the dog to its jawbone. There are three types of epulis; fibromatous, ossifying and acanthomatous.
Symptoms of Tumors of the Gums (Epulis) in Dogs
The growth that forms between the dog’s teeth is generally firm, similar in color to the gums and smooth. Some epulides will present with a peduncle attaching it to the gum.
- Bleeding from mass
- Difficulty chewing
- Displaced teeth
- Drooling
- Loss of appetite
- Pink, raised growth
- Reduced activity level
- Swelling of jaw bones
- Tooth loss
- Unusually bad breath
- Weight loss
Types
Fibromatous - Growth of tough, fibrous tissue usually located at the margin of the gum, generally smooth and pink, without ulcerations; this is the least likely to require additional treatments such as cryosurgery or chemotherapy
Ossifying - Nonulcerated smooth, pink growth that contains bone cells; this type of epulis is more likely to require radical surgery or to become cancerous
Acanthomatous - Tumor that originates from the periodontal ligament that holds the root of the tooth in the bone; these cancers are usually found in the front portion of the lower jaw and can be either ulcerated or non-ulcerated; these growths are considered benign but can prove to be locally invasive, so treatment is usually more aggressive
Causes of Tumors of the Gums (Epulis) in Dogs
Although these are one of the more common growths that can be found in a canine’s mouth, the cause or causes of epulides have eluded scientists to this point. Most epulis tumors develop in dogs older than six years old, and Boxers seem to be slightly predisposed to developing these growths.
Diagnosis of Tumors of the Gums (Epulis) in Dogs
The veterinarian will first want to acquire your dog’s complete health history. A complete blood count, blood chemistry profile, and urinalysis will also be performed to evaluate the overall health of the patient. A sample of the tumor will be taken, usually by incisional biopsy, and a dental x-ray will also be done to reveal dental changes or invasion into the jaw bone itself. X-rays of the chest area may also be done if the veterinarian is concerned about the spread of the cancer to remote locations such as the lung. An MRI may be employed to assess the size of the mass and whether or not it has invaded nearby structures and a CT scan may give a clearer picture of calcification or erosion of the outer layer (cortex) of the bones that have been affected. The biopsy of the tissue sample will determine if it is indeed an epulis, and which type of epulis it is.
Treatment of Tumors of the Gums (Epulis) in Dogs
Benign tumors such as epulis, as well as a portion of the surrounding tissue, will generally be excised to avoid further spread into surrounding tissues. With ossifying and acanthomatous epulis there is a likelihood of the jaw being involved. If this is the case, part or all of that portion of the jaw may need to be surgically removed. The excision of all or part of the jaw is referred to as a maxillectomy if it affects the top of the jaw or mandibulectomy if the bottom of the jaw is involved. With ossifying epulis cryosurgery may be employed as well to help ensure that all of the abnormal tissues are fully removed. Cryosurgery is the application of extreme cold to destroy abnormal or diseased tissue. As the acanthomatous variety of epulis can be known to become very invasive to surrounding tissues it considered a cancerous growth and its treatment is often more aggressive, involving radiation and possibly chemotherapeutic agents.
Recovery of Tumors of the Gums (Epulis) in Dogs
After any surgical excision, it is essential to keep the site clean and make sure to remove dirt and debris. You will need to examine the site regularly for swelling, bleeding or pus, and keep your dog from interfering with it. Keeping the recovering patient in a calm and quiet environment will help speed healing, as will having appropriate food and water within easy reach. Specialized feeding and care instructions may be given by your veterinarian to facilitate healing. If a mandibulectomy or maxillectomy was performed due to invasion of the growth into the bone, then your dog may have a protruding tongue where the bone was removed until they get used to retracting their tongue on their own. You may also observe an increase in salivation and clicking noises that occur when your dog chews. There may also be a visible narrowing or drooping of the nose due to the removal of the upper jaw bone.
Tumors of the Gums (Epulis) Questions and Advice from Veterinary Professionals
Has Symptoms
I took my dog to the vet for a growth I noticed on his gums. It's the same pink color of his gums. My vet said it was Epulis nothing to worry about after further eval he noticed his lymph nodes were enlarged and took a sample of the lymph nodes to send to the lab to check for cancer. can this be related to the Epulis?

15 year old black lab has a black and pink mass growing from upper gum. 3 weeks ago it was just a bump on her gum, vet thought it was an abscess so we had broken carnissial tooth removed. They did a biopsy of the mass and it came back benign. Now mass is large and bleeds intermittently, could this be a epulis?

5 month old puppy has a grayish growth on bottom gum the gods from from to back around the lower right canine. His appetite is good and just had an oral exam 2 months ago where nothing was found. He has gone to training classes and there is another puppy in the house. There doesn't seem to halitosis and it doesn't appear to cause him any discomfort or pain. Thanks in advance for any insight on this.

Whilst I cannot say for 100% the cause, with Buddy’s age I would suspect canine oral papillomavirus. In many cases the growths resolve themselves but may require surgery in some cases; you should visit your Veterinarian to check to make sure that there isn’t anything more serious happening. The growths can be smooth or look like cauliflower. Regards Dr Callum Turner DVM

My Cane Corso had and Epulis removed from her canine tooth a year ago by her vet and it is coming back. Should I see a specialist for this instead of her vet, and if so , what type of specialist should I see?

Can a Vet take off an Epulis or should a Vet dentist? I want my Vet to take my dogs Epulis off but I am concerned he won't get all the root and it will grow back. My Vet is going to excise it flush with gum and biopsy it.

(I think my first post did not go through.)
What can be done to prevent or slow down epulis. My 5 year old boxer had surgery for this, for the second time. His first surgery was at age 3 years old. It covered up his bottom front teeth both times. Also had some epulis bumps removed from his top gums both surgeries. Thank you for any advice you can offer.

My dog has a growth on his gums which the vet was not concerned about. Vet stated he would suggest having it removed if he needed any other procedures. This was several months ago. Yesterday I noticed it has grown and the color has changed to a grayish black color. He plays normal, eats and drinks but he has been throwing up almost daily at least 1x. I am very concerned and the vet cannot see him until Tuesday.

My vet saw my 9 yr old Shih Tzu today and thought she had a epulis but she’ll know more when my dog gets her teach cleaned in a week and can look at it closer. What does that mean? My dog had cataract surgery last year so whatever is wrong needs to fixed when she’s under anesthesia for her teeth cleaning am I right? I’m so scares

My dog has a weird blue/gray mass like thing on his right side gum, it seems to be growing, and has started to show on the left side of his mouth. he has no trouble eating or drinking. it doesn't seem to bother him, im just worried that it could turn into something bad.

It would be best to have your Veterinarian take a look at the mass as it is possible that the mass may be malignant or caused by some other underlying condition. Whilst it doesn’t cause any trouble now, masses in the oral cavity may ulcerate leading to secondary infections and other problems; if it is cancerous (unlikely in a young dog) it may spread.
