Have you ever noticed a lump, swelling, or unusual growth in your pet’s mouth? While some oral lumps may be harmless, others could be a sign of a serious health issue, including oral tumors or cancer. Since pets don’t often show obvious signs of discomfort, these growths can go undetected until they become severe.

February is Pet Dental Health Month—a time to raise awareness about the importance of regular dental exams and X-rays. At TruVet Pet Hospital, we encourage pet owners to maintain routine at-home dental care and professional pet dentistry in Frisco, TX. By examining your pet’s mouth regularly, oral tumors can be diagnosed early for more effective treatment. 

Are Oral Lumps Always Cancerous?

Not all lumps in your pet’s mouth are cancerous, but any abnormal growth should be examined by a veterinarian. Some oral masses are benign (non-cancerous), while others can be malignant (cancerous and aggressive). The key to protecting your pet’s health is early detection and diagnosis. Even if your pet isn’t showing any signs of pain, any lumps or bumps should be checked by a veterinarian.

Here are some of the most common causes of oral lumps in pets:

• Oral Papillomas: Viral warts found commonly in younger pets, usually resolving on their own.
• Epulis: A benign mass that forms near the gumline but may still require removal.
• Gingival Hyperplasia: Overgrowth of gum tissue.
• Malignant Tumors (Oral Cancer): Includes squamous cell carcinoma, melanoma, and more, which can spread aggressively if left untreated.

Signs Your Pet May Have an Oral Tumor

Because pets are skilled at hiding discomfort or pain, owners often don’t notice a tumor until it becomes large enough to affect daily activities. You can look for warning signs that your pet may be experiencing oral issues.

• Persistent Bad Breath: A persistent foul odor may indicate infection, decay, or a tumor.
• Excessive Drooling: More saliva than usual can be a reaction to oral discomfort.
• Difficulty Eating: Your pet may drop food or avoid hard kibble.
• Loose or Missing Teeth: Some tumors weaken the tissue supporting the teeth.
• Bleeding from the Mouth: Unexplained bleeding from the gums or tongue can be a red flag.
• Swelling of the Face or Jaw: Some oral tumors can cause noticeable swelling.
• Visible Lump or Mass Inside Mouth: If you notice an abnormal growth, schedule a vet visit immediately.

How Are Oral Tumors in Pets Diagnosed?

If your vet suspects an oral tumor, they will perform a thorough dental exam. A physical oral inspection will be performed, checking for lumps, swelling, or gum abnormalities in your pet’s mouth. Dental X-rays under anesthesia can be used to assess bone involvement or hidden tumors. A tissue sample may be collected for a biopsy to determine whether the tumor is benign or malignant. If the tumor is suspected to be invasive, advanced imaging may be recommended.

Why Regular Dental Exams with a Vet Are So Important

Oral tumors can develop without noticeable symptoms, which is why routine pet dental exams and cleanings should be a part of your cat or dog’s yearly routine. Gum infections and poor oral health can increase the risk of complications and development of oral issues. Catching tumors early increases the chances of successful treatment. Some tumors grow inside the jawbone before becoming visible, so X-rays are recommended for all pet dental cleanings.

Early Detection Can Save Your Pet’s Life

Not all oral lumps are cancerous, but every growth should be examined by a vet. Since many tumors are found during routine dental exams, taking advantage of dental care at TruVet Pet Hospital is a great way to make sure your pet’s mouth stays healthy.
