Gingivitis in Pigs: Red, Swollen Gums and Dental Pain

Quick Answer
  • Gingivitis in pigs is inflammation of the gums, usually linked to plaque, tartar, trapped feed, tooth overgrowth, or other dental disease.
  • Common signs include red or puffy gums, bad breath, dropping food, chewing slowly, bruxism, reduced appetite, and weight loss.
  • Mild gum inflammation is not always an emergency, but a pig that stops eating, seems painful, drools, or has facial swelling should see your vet promptly.
  • Treatment often involves an oral exam, sedation or anesthesia for a full dental assessment, cleaning of tartar, trimming overgrown canines when needed, pain control, and treatment of any infected or damaged teeth.
  • Typical US cost range in 2026: about $90-$250 for an exam and basic oral assessment, $400-$1,200 for sedated dental cleaning and tusk trimming, and $1,200-$3,500+ if dental radiographs, extractions, abscess treatment, or advanced anesthesia monitoring are needed.
Estimated cost: $90–$3,500

What Is Gingivitis in Pigs?

Gingivitis is inflammation of the gum tissue around the teeth. In pigs, pet parents may first notice gums that look red, puffy, or tender, along with bad breath or signs of mouth pain. The problem can stay mild for a while, but it may progress if plaque, tartar, tooth overgrowth, or infection are not addressed.

Mini pigs and older pigs can develop dental problems that make gingivitis more likely. Merck notes that permanent canine teeth in miniature pet pigs grow continuously and can become excessively long, leading to malocclusion and pain. Tartar can also build up and may need to be removed during a sedated dental procedure.

Gingivitis is different from deeper periodontal disease, where inflammation extends below the gumline and starts damaging the tissues that support the tooth. That distinction matters because early gum inflammation may improve with timely dental care, while advanced disease can involve loose teeth, tooth-root infection, or abscesses.

Because pigs often hide discomfort, even subtle changes in eating or behavior deserve attention. A pig with sore gums may still approach food but chew more slowly, drop pellets, or avoid harder items.

Symptoms of Gingivitis in Pigs

  • Red, swollen, or irritated gums
  • Bad breath
  • Pain when chewing or reluctance to chew hard food
  • Dropping food from the mouth
  • Eating more slowly or reduced appetite
  • Bruxism or teeth grinding
  • Drooling or wetness around the mouth
  • Weight loss or poor body condition
  • Bleeding from the gums
  • Facial swelling, draining tract, or jaw tenderness

Watch for both mouth changes and behavior changes. Pigs with dental pain may become quieter, resist having the face touched, or stop finishing meals. Merck specifically notes that anorexia or bruxism in miniature pet pigs can be associated with significant dental disease, including exposed or abscessed tooth roots.

See your vet promptly if your pig is eating less, losing weight, drooling, or showing clear pain. See your vet immediately if there is facial swelling, a draining wound near the jaw, or your pig stops eating, because pigs can decline quickly when painful oral disease interferes with normal feeding.

What Causes Gingivitis in Pigs?

The most common driver of gingivitis is bacterial plaque that collects along the gumline. Over time, plaque can harden into tartar, which irritates the gums and makes it easier for more bacteria to stay in place. Merck's dental guidance across species emphasizes that plaque removal is central to reversing gingivitis and preventing progression.

In pigs, anatomy and tooth growth can add another layer. Miniature pet pigs have continuously growing canine teeth, and when these become excessively long they can contribute to malocclusion, pain, and abnormal wear. Food packing around crowded or misaligned teeth may also worsen gum inflammation.

Diet and husbandry matter too. VCA advises feeding a nutritionally complete, balanced pelleted diet formulated for mini pigs rather than relying on unverified homemade or internet diets. Poor nutrition does not directly cause every case of gingivitis, but it can make overall oral and tissue health harder to maintain.

Other possible contributors include tooth-root infection, oral trauma, retained feed material, foreign material in the mouth, and less commonly systemic illness or immune-mediated inflammation. Mouth sores in pigs can also have infectious causes, so your vet may need to rule out conditions that are not routine dental disease.

How Is Gingivitis in Pigs Diagnosed?

Diagnosis starts with a history and physical exam. Your vet will ask about appetite, chewing changes, weight loss, bad breath, drooling, and any behavior that suggests oral pain. A brief awake look at the mouth may show red gums or obvious tusk overgrowth, but pigs often need sedation for a complete and safe oral exam.

Merck's miniature pig guidance notes that sedation and examination of the oral cavity, with or without endoscopy, are indicated when anorexia or bruxism is reported. During a sedated exam, your vet may assess the gums, tooth alignment, tartar buildup, loose teeth, ulcers, and signs of deeper periodontal disease.

If your vet suspects a tooth-root abscess or advanced dental disease, dental radiographs may be recommended. Merck notes that radiographic evaluation may be necessary to diagnose tooth-root abscesses in miniature pet pigs, especially when there is swelling near the angle of the mandible.

Diagnosis is not only about naming gingivitis. It is also about finding the reason behind it, because treatment can look very different for simple plaque buildup versus overgrown canines, periodontal pockets, fractured teeth, or a draining abscess.

Treatment Options for Gingivitis in Pigs

Spectrum of Care means you have options. Here are treatment tiers at different price points.

Budget-Conscious Care

$90–$350
Best for: Mild signs, early gum inflammation, or pet parents who need to start with the most essential first steps while planning further care
  • Office exam and history review
  • Awake oral assessment as tolerated
  • Discussion of diet, feeding texture, and husbandry factors
  • Short-term pain-control plan if your vet feels it is appropriate
  • Monitoring body weight and food intake at home
  • Referral planning if a full sedated dental procedure is not possible that day
Expected outcome: Often fair to good for comfort in the short term if disease is mild, but lasting improvement depends on addressing plaque, tartar, and any tooth abnormalities.
Consider: Lower upfront cost, but it may miss disease below the gumline. Awake exams cannot fully evaluate many pigs, and tartar or painful tooth problems usually are not resolved without sedation or anesthesia.
Most Common

Recommended Standard Treatment

$400–$1,200
Best for: Most pigs with persistent gingivitis, tartar buildup, bad breath, chewing discomfort, or visible tusk overgrowth
  • Pre-anesthetic exam and basic lab work as recommended
  • Sedation or anesthesia for a complete oral exam
  • Dental cleaning with manual or powered scaling and polishing
  • Canine trimming if overgrowth is contributing to malocclusion or trauma
  • Targeted medications chosen by your vet for pain and infection risk when indicated
  • Discharge plan with feeding guidance and follow-up
Expected outcome: Good in many uncomplicated cases when plaque and tartar are removed and contributing dental issues are corrected early.
Consider: Requires sedation or anesthesia, which adds cost and planning. Some disease may turn out to be more advanced than expected, increasing the final cost range.

Advanced / Critical Care

$1,200–$3,500
Best for: Complex cases, geriatric pigs, pigs with facial swelling or suspected tooth-root abscess, and pet parents wanting every reasonable diagnostic and treatment option
  • Advanced anesthesia monitoring and longer procedure time
  • Full-mouth dental radiographs when available
  • Treatment of periodontal pockets or severe tartar burden
  • Extraction of diseased teeth or management of tooth-root abscesses
  • Culture or additional diagnostics in complicated infections
  • Hospitalization, assisted feeding support, and specialty or referral care for severe pain, facial swelling, or poor intake
Expected outcome: Variable but often improved when the painful source is identified and treated. Outcome depends on how advanced the disease is and whether bone or tooth roots are involved.
Consider: Most thorough approach, but it has the highest cost range and may require referral to an exotics-focused or dental-experienced veterinary team.

Cost estimates as of 2026-03. Actual costs vary by location, clinic, and individual case.

Questions to Ask Your Vet About Gingivitis in Pigs

Bring these questions to your vet appointment to get the most out of your visit.

  1. Does this look like simple gingivitis, or do you suspect deeper periodontal disease or a tooth-root problem?
  2. Does my pig need sedation or anesthesia for a complete oral exam?
  3. Are the canine teeth overgrown or causing malocclusion, trauma, or trapped food?
  4. Would dental radiographs help in my pig's case?
  5. What treatment options fit my pig's needs and my budget right now?
  6. What signs at home would mean the problem is getting worse?
  7. What should I feed while my pig's mouth is sore?
  8. How often should my pig have oral rechecks or preventive dental care?

How to Prevent Gingivitis in Pigs

Prevention focuses on reducing plaque buildup and catching dental changes early. Feed a balanced diet formulated for mini pigs, and avoid relying on unverified homemade feeding plans. VCA specifically recommends a nutritionally complete pelleted mini-pig diet as the foundation for overall health.

Regular veterinary exams matter because pigs often hide oral pain. During routine visits, ask your vet to look at the mouth, gumline, and canine length. In some pigs, periodic canine trimming is needed. Merck notes that miniature pet pig canines may need trimming every 6 to 12 months when they become excessively long.

Good prevention also means paying attention at home. Watch for bad breath, slower chewing, dropping food, bruxism, or weight loss. These signs can appear before obvious facial swelling or severe disease develops.

Do not attempt tusk trimming or dental scaling at home. Merck warns that improper cutting can fracture the tooth and lead to pain and infection, and awake cosmetic cleaning does not address disease below the gumline. The safest plan is a preventive partnership with your vet, using the level of care that fits your pig's needs.
