Here is a thorough guide to treating and managing mouth ulcers (aphthous stomatitis), based on multiple medical textbooks including Cummings Otolaryngology, Andrews' Diseases of the Skin, and Tintinalli's Emergency Medicine:
Mouth Ulcers (Aphthous Stomatitis) - How to Treat Them
What They Are
Aphthous ulcers are small, round, shallow, painful white ulcers surrounded by a red ring. They appear on the soft (non-keratinized) inner surfaces of the mouth - cheeks, inner lips, tongue edges, and soft palate. Most are about 3-10 mm in size and heal on their own in 7-14 days.
There are three types:
- Minor aphthae (most common): less than 10 mm, heal in 10-14 days
- Major aphthae (Sutton disease): larger, deeper, take 2-12 weeks to heal, may scar
- Herpetiform aphthae: clusters of tiny 1-3 mm ulcers that coalesce
Treatments
Step 1 - Mild/Infrequent Ulcers (First-Line)
| Treatment | How to Use |
|---|---|
| Chlorhexidine 0.2% mouthwash | Rinse 1-2x daily - reduces pain and speeds healing |
| Topical anesthetics (benzocaine, viscous lidocaine 2%) | Apply directly to ulcer for temporary pain relief before eating |
| Topical steroids (triamcinolone acetonide in Orobase paste) | Apply to ulcer 2-4x daily - reduces inflammation and speeds healing |
| Bioadhesive pastes (e.g., Orobase) | Contains steroid + anesthetic, sticks to the mucosal surface |
These topical agents are the first-line therapy for the majority of cases. - Tintinalli's Emergency Medicine, p. 1984; Cummings Otolaryngology, p. 2482
Step 2 - Persistent or Severe Ulcers
- Short course of oral corticosteroids (e.g., prednisone) for severe or continuous outbreaks
- Intralesional steroid injections for major aphthae not responding to topicals
Step 3 - Recurrent/Refractory Cases (Specialist-Managed)
When ulcers recur so often that you need steroids more than 2-3 times a year, alternatives include:
- Colchicine
- Dapsone
- Thalidomide
- Azathioprine
- TNF-alpha antagonists
Home Remedies & Lifestyle Tips
- Avoid triggers: spicy food, citrus fruits (lemons/oranges), fresh pineapple, walnuts, chocolate, tomatoes
- Manage stress - psychological stress is a well-documented trigger
- Avoid trauma: be gentle with toothbrush, avoid biting the inside of your cheek
- Saltwater rinses: warm salty water rinses soothe pain (not curative but helpful)
- Honey or aloe vera gel applied topically - some evidence of benefit in small studies
Address Underlying Deficiencies
Vitamin and nutritional deficiencies are a common, correctable cause of recurrent mouth ulcers. Get blood tests for:
- Vitamin B12 deficiency
- Iron deficiency / anemia
- Folate (Vitamin B9) deficiency
- Zinc deficiency
Correcting deficiencies often stops recurrences. - Andrews' Diseases of the Skin, p. 2489
When to See a Doctor
See a doctor if:
- Ulcers are larger than 1 cm, very deep, or last more than 3 weeks without healing
- You have ulcers plus genital sores, eye inflammation, or skin lesions (may suggest Behcet syndrome)
- Ulcers occur along with fever, swollen glands, weight loss (can indicate HIV, Crohn's, celiac disease, or blood disorders)
- You have very frequent recurrences (several times per year) that significantly affect eating/speaking
- A child has periodic fever with ulcers every month (consider PFAPA syndrome)
What Does NOT Work
- Antibiotics (unless there's a secondary bacterial infection)
- Antiviral drugs (mouth ulcers are NOT the same as cold sores/herpes - they are not caused by a virus)
Recent evidence note: A 2026 umbrella review (PMID 41626665) confirms topical corticosteroids and chlorhexidine as the best-supported treatments for recurrent aphthous stomatitis. A systematic review (PMID 37786470) also found topical licorice gel has promising evidence for reducing pain and ulcer size.
