Gingival Ulceration
What is Gingival Ulceration?
Gingival ulceration refers to a break in the surface of the gum tissue (the gingiva) that creates an open sore. The ulcer can range from a tiny pinpoint lesion to a larger, painful crater‑like defect. Because the gums are highly vascular, ulcerations often bleed easily and can become secondarily infected if not managed promptly.
These lesions are usually noticed as a red or white patch that may develop a yellow‑gray base, a surrounding halo of inflammation, and a sensation of burning or sharp pain, especially when eating, brushing, or speaking.
While many gingival ulcers are benign and self‑limiting, they can sometimes signal an underlying systemic disease, infection, or medication reaction. Accurate identification of the cause is essential for proper treatment and to prevent complications such as chronic pain, periodontal disease, or, in rare cases, malignancy.

Common Causes
Below are the most frequent conditions and factors that can produce ulceration of the gums:
- Traumatic injury: accidental bites, sharp tooth edges, ill‑fitting dental appliances, or aggressive brushing.
- Aphthous stomatitis (canker sores): recurrent, small, shallow ulcers that often appear on non‑keratinized oral mucosa, including the gingiva.
- Herpes simplex virus (HSV) infection: primary herpetic gingivostomatitis and recurrent HSV‑1 lesions.
- Periodontal disease: advanced gingivitis or periodontitis can lead to necrosis and ulcer formation in the interdental papillae.
- Medication‑induced ulcers: non‑steroidal anti‑inflammatory drugs (NSAIDs), chemotherapeutic agents, bisphosphonates, and immune checkpoint inhibitors.
- Systemic autoimmune disorders: Behçet’s disease, pemphigus vulgaris, mucous membrane pemphigoid, and lupus erythematosus.
- Infectious organisms: bacterial (e.g., Treponema pallidum – syphilis), fungal (candidiasis), or parasitic (protozoal) infections.
- Vitamin and mineral deficiencies: especially deficiencies of B‑12, iron, folate, or vitamin C (scurvy).
- Smoking and tobacco‑related lesions: tobacco‑induced necrotizing gingivitis can ulcerate.
- Oral squamous cell carcinoma (OSCC): a malignant ulcer that does not heal within 2–3 weeks and may have indurated borders.
Associated Symptoms
Gingival ulceration often does not occur in isolation. Typical accompanying features include:
- Pain or burning sensation, especially on contact with hot, acidic, or spicy foods.
- Bleeding that may be spontaneous or provoked by brushing or chewing.
- Swelling or edema of the surrounding gingiva.
- Redness (erythema) and a white or yellowish pseudomembrane covering the ulcer.
- Bad taste or foul odor (halitosis) caused by necrotic tissue or secondary infection.
- Fever, malaise, or lymphadenopathy when the ulcer is part of a systemic infection (e.g., HSV, syphilis).
- Recurrent episodes of similar lesions in different locations of the mouth.
- Difficulty opening the mouth (trismus) or speaking clearly if the ulcer is large.
When to See a Doctor
Most small, painless gingival ulcers resolve on their own within 1–2 weeks. However, you should schedule a dental or medical appointment if you notice any of the following:
- The ulcer persists longer than 14 days without improvement.
- Severe or worsening pain that interferes with eating, drinking, or speaking.
- Unexplained weight loss or loss of appetite.
- Repeated ulcerations (more than three episodes in a year).
- Visible signs of infection: pus, increasing redness, fever, or swollen lymph nodes.
- Bleeding that does not stop after applying gentle pressure.
- Any ulcer with an indurated (hard) base, raised edges, or a “rolled” border – these may suggest malignancy.
- History of systemic disease (e.g., diabetes, autoimmune disease) or recent chemotherapy/radiation therapy.
Prompt evaluation helps rule out serious conditions and initiates appropriate therapy, reducing the risk of complications.
Diagnosis
Evaluation of gingival ulceration typically follows a stepwise approach:
1. Clinical examination
- Visual inspection using a dental mirror and adequate lighting to assess size, number, margin, base, and surrounding tissue.
- Palpation to check for induration, fluctuation (suggesting abscess), or tenderness.
- Documentation of location (e.g., attached gingiva vs. free gingiva, interproximal papillae).
2. Medical and dental history
- Recent trauma, new medications, systemic illnesses, smoking status, and oral hygiene practices.
- History of similar lesions, family history of autoimmune disease, or known cancers.
3. Laboratory investigations (when indicated)
- Complete blood count (CBC) and iron studies – to detect anemia or infection.
- Serum vitamin B12, folate, and vitamin C levels – for deficiency‑related ulcers.
- Serologic testing for HSV, syphilis (RPR/VDRL), HIV, or hepatitis when risk factors exist.
- Autoimmune panels (ANA, anti‑dsDNA, ENA) if a connective‑tissue disease is suspected.
4. Microbiological testing
- Swab or culture for bacterial or fungal pathogens if secondary infection is suspected.
- PCR testing for HSV or other viral agents.
5. Biopsy
- Excisional or incisional biopsy of ulcers that persist >3 weeks, have atypical appearance, or present in high‑risk patients (e.g., tobacco users, heavy alcohol use).
- Histopathology can differentiate benign ulceration from malignancy, autoimmune bullous disease, or granulomatous conditions.
6. Imaging (rare)
- Panoramic radiographs or cone‑beam CT may be ordered if underlying bony involvement (e.g., osteonecrosis from bisphosphonates) is suspected.
Treatment Options
Treatment is tailored to the underlying cause, ulcer size, and symptom severity. Below are the main therapeutic pathways.
1. General oral care measures
- Rinse gently with a warm saline solution (½ tsp salt in 8 oz water) 3–4 times daily to keep the area clean.
- Use a soft‑bristled toothbrush and avoid vigorous scrubbing.
- Maintain good overall oral hygiene – brushing twice daily and flossing carefully.
2. Topical agents
- Antimicrobial mouthwash: chlorhexidine 0.12 % swish‑and‑spit for 30 seconds, 2 × daily (avoid prolonged use >2 weeks to prevent staining).
- Topical corticosteroids: triamcinolone acetonide 0.1 % gel or dexamethasone elixir applied 2–3 × daily for inflammatory or autoimmune ulcers.
- Barrier agents: petroleum‑jelly or hyaluronic‑acid gels to protect the ulcer from mechanical irritation.
- Analgesic gels: benzocaine 20 % or lidocaine 2 % for short‑term pain relief.
3. Systemic medications
- Antivirals: acyclovir 400 mg PO five times daily for 7–10 days (primary HSV gingivostomatitis) or valacyclovir 1 g PO BID.
- Antibiotics: amoxicillin‑clavulanate 875/125 mg PO BID for 7 days if bacterial superinfection is evident.
- Systemic corticosteroids: prednisone 0.5 mg/kg PO daily tapered over 1–2 weeks for severe autoimmune ulcerations.
- Immunomodulators: colchicine, dapsone, or thalidomide may be employed for refractory aphthous ulcers under specialist guidance.
4. Management of underlying systemic disease
- Correct vitamin deficiencies with supplementation (e.g., cyanocobalamin 1000 µg PO daily for B12 deficiency).
- Control diabetes, adjust immunosuppressive regimens, or treat Behçet’s disease with colchicine or biologics as directed by a rheumatologist.
5. Surgical interventions (rare)
- Excision of necrotic tissue or curettage of a deep ulcer under local anesthesia to promote healing.
- Laser de‑epithelialization for chronic, painful ulcers not responding to medical therapy.
6. Follow‑up care
- Re‑evaluate the lesion after 1–2 weeks of therapy. If no improvement, consider referral to an oral surgeon, periodontist, or oral medicine specialist.
- Document healing progress with photographs when possible.
Prevention Tips
Although some causes (e.g., viral infections) cannot be entirely prevented, many risk factors are modifiable.
- Practice gentle oral hygiene: use soft brushes, avoid flossing aggressively, and replace toothbrushes every 3 months.
- Protect against trauma: ensure dental restorations, crowns, and orthodontic appliances fit correctly; use a night guard if you grind teeth.
- Maintain nutrition: eat a balanced diet rich in vitamins B12, C, folate, and iron; consider a multivitamin if dietary intake is limited.
- Quit smoking and limit alcohol: both are linked to necrotizing gingivitis and oral malignancies.
- Manage systemic conditions: keep diabetes, autoimmune disease, and HIV well‑controlled.
- Stay up to date on vaccinations: especially for HSV (experimental vaccines) and HPV (prevents certain oral cancers).
- Regular dental check‑ups: routine professional cleanings and examinations catch early signs of periodontal disease or lesions before they ulcerate.
- Medication review: discuss with your physician or dentist any new drugs that might cause oral ulceration (e.g., NSAIDs, bisphosphonates).
Emergency Warning Signs
- Severe, uncontrolled bleeding from the ulcer (e.g., cannot stop after 10 minutes of firm pressure).
- Rapidly spreading infection with high fever, chills, or facial swelling.
- Difficulty breathing or swallowing due to swelling of the oral floor or tongue.
- Sudden onset of intense pain accompanied by a foul odor, indicating possible necrotizing infection.
- Ulcer that turns black, develops a hard indurated base, or shows no signs of healing after 3 weeks.
- Generalized weakness, unexplained weight loss, or night sweats suggestive of systemic illness.
If any of these signs occur, seek emergency medical or dental care immediately.
Understanding the nature of gingival ulceration enables you to act quickly, seek the right care, and adopt habits that protect your oral health. When in doubt, always consult a dental professional or your primary care provider.
