In a tobacco-chewing 23-year-old with oral ulcers and burning, do not assume aphthous ulcer alone. The first priority is to exclude a traumatic lesion, candidiasis, oral submucous fibrosis, lichen planus, leukoplakia/erythroplakia, and early oral squamous-cell carcinoma.
Same-day assessment
- Record duration, recurrence, exact tobacco product and site of placement, areca nut/gutka, alcohol, dental trauma, medications, fever, genital/skin/eye symptoms, weight loss, dysphagia, odynophagia, and immunosuppression/HIV risks.
- Examine and photograph/map: buccal mucosa, gingivobuccal sulcus, tongue especially lateral/ventral surface, floor of mouth, palate, and oropharynx.
- Palpate ulcer margins/base for induration, assess mouth opening and fibrous bands, and palpate cervical nodes.
- Look for a non-scrapable white patch, red or mixed red-white lesion, bleeding, irregular/rolled edge, or fixation.
Management now
1. Stop the causative exposure
Advise complete cessation of chewing tobacco, gutka, betel quid and areca nut immediately. Explain that merely changing the placement site is not acceptable. Burning with restricted mouth opening or palpable fibrous bands suggests oral submucous fibrosis and needs specialist assessment.
Also advise:
- Avoid spicy, acidic, very hot foods and alcohol-containing mouthwashes.
- Gentle brushing, hydration.
- Warm saline or sodium-bicarbonate mouth rinses 3-4 times/day.
- Correct sharp tooth, restoration, denture, or other local trauma through a dentist.
2. Symptomatic treatment, only while evaluating
If the lesion is clearly a short-duration, non-indurated traumatic or minor aphthous ulcer and there is no suspicious red/white lesion:
- Paracetamol 500 mg to 1 g orally every 6-8 hours as needed, maximum 3 g/day in most adults. Adjust for liver disease/alcohol use.
- If suitable, ibuprofen 200-400 mg orally every 8 hours after food as needed for 2-3 days. Avoid with peptic ulcer disease, renal disease, anticoagulants, uncontrolled hypertension, NSAID allergy, and pregnancy.
- Benzydamine 0.15% mouthwash 15 mL rinse/gargle and spit every 1.5-3 hours as needed for pain, if locally available.
- For confirmed aphthous-type ulcers, triamcinolone acetonide 0.1% oral paste, a thin film directly over a dried ulcer 2-4 times daily after meals for up to 5-7 days.
Do not start topical steroids if there is clinical candidiasis, herpetic-type vesicular disease, or a suspicious persistent ulcer. Do not give empirical antibiotics unless there is a separate bacterial dental/soft-tissue infection.
If there are typical scrapable white plaques with erythematous painful mucosa, confirm candidiasis and look for diabetes, inhaled steroid use, antibiotics, HIV risk, or immunosuppression before treating. Nystatin can be used when candidiasis is clinically supported, but it is not routine treatment for an undifferentiated ulcer.
Refer urgently for biopsy / oral medicine / OMFS / ENT
Arrange urgent referral now if:
- Ulcer is present >2 weeks, or fails to substantially heal after eliminating trauma within 2 weeks.
- Indurated, irregular, deep, bleeding, painless/nonhealing, with rolled edges.
- Non-scrapable leukoplakia, erythroplakia, or mixed red-white lesion.
- Lesion on lateral/ventral tongue, floor of mouth, soft palate, or lower lip.
- Cervical lymphadenopathy, trismus, dysphagia, weight loss, voice change, or referred otalgia.
Persistent oral ulcers warrant investigation because malignancy can present this way. Harrison's specifically flags chronic ulcers and red-white lesions lasting over two weeks for early diagnostic biopsy, with smokeless tobacco and betel mixtures being important risk factors in South Asia -
Harrison's Principles of Internal Medicine, p. 305. Current oral-cancer prevention guidance similarly recommends immediate specialist referral for a clinically suspicious mucosal lesion, as summarized in the
UK oral cancer guidance.
Basic investigations if recurrent, multiple, or atypical
- CBC with differential
- Ferritin/iron studies, vitamin B12, folate
- Blood glucose or HbA1c
- HIV test with consent where clinically indicated
- Consider ESR/CRP, celiac work-up, or autoimmune evaluation only if history suggests systemic disease.
Bottom line: give analgesia and local care, stop tobacco immediately, correct trauma, but a tobacco chewer with a persistent ulcer should be referred for biopsy rather than repeatedly treated with steroid gels or antibiotics.
