Treatment for Stomatitis
Begin treatment with sodium bicarbonate-containing mouthwash (1 teaspoon salt with three-quarter teaspoon baking soda in 500 mL water) 4-6 times daily, combined with basic oral hygiene using non-alcoholic mouthwashes, then escalate to topical corticosteroids based on severity. 1
Initial Management for All Types of Stomatitis
- Establish foundational oral care with non-alcoholic, sodium bicarbonate-containing mouthwashes used 4-6 times daily to maintain oral pH and reduce inflammation 2, 1, 3
- Avoid alcoholic mouthwashes entirely, as they aggravate mucosal irritation and worsen symptoms 1
- Maintain gentle oral hygiene with mild toothpaste and soft-bristled brushing 1
Severity-Based Treatment Algorithm
Mild Stomatitis (Grade 1-2)
- Continue sodium bicarbonate rinses 4-6 times daily for symptomatic relief 1, 3
- Apply topical anesthetics such as viscous lidocaine 2% before meals for pain control 2, 1, 3
- Consider barrier preparations like Gengigel or Gelclair for additional pain management 3
- Use ice chips or ice pops as needed to numb the mouth 1
Moderate Stomatitis
- Increase sodium bicarbonate mouthwash frequency up to hourly if necessary 2, 3
- Initiate topical high-potency corticosteroids as first-line therapy: 2, 1, 3
- Dexamethasone mouth rinse (0.1 mg/mL): 10 mL swish for 2 minutes then spit, four times daily for multiple or difficult-to-reach ulcerations 2, 1
- Clobetasol gel or ointment (0.05%): applied twice daily for limited, easily accessible ulcers 2, 3
- Betamethasone sodium phosphate 0.5 mg dissolved in 10 mL water as rinse-and-spit 1-4 times daily 3
- Apply topical NSAIDs (amlexanox 5% oral paste) for moderate pain if NSAIDs are tolerated 2
- If NSAIDs are contraindicated, use acetaminophen as maintenance therapy combined with immediate-release oral opioids 2
Severe or Recalcitrant Stomatitis (Grade 3-4)
- Administer systemic corticosteroids: prednisone 30-60 mg or 1 mg/kg daily for 1 week, followed by dose tapering over the second week for highly symptomatic or recurrent ulcers 2, 1
- Consider intralesional steroid injection (triamcinolone weekly, total dose 28 mg) in conjunction with topical clobetasol for ulcers that fail to resolve 2, 3
- Use alternative administration routes (transdermal or intranasal) for analgesics when oral intake is compromised 2, 1
- Fast-acting fentanyl preparations (50 μg nasal spray) may be considered for short-term pain relief, particularly before meals, in patients already on opioid therapy 2
- Hospitalization is required for Grade 3-4 stomatitis with inability to maintain oral intake 1
Specific Stomatitis Subtypes
mTOR Inhibitor-Associated Stomatitis (mIAS)
- Start prophylactic dexamethasone mouthwash (0.5 mg/5 mL, 10 mL swish for 2 minutes then spit, four times daily) before initiating mTOR inhibitor therapy 1
- This represents the most effective prevention strategy for drug-induced stomatitis 1
Angular Stomatitis
- Apply topical antifungal agents as primary treatment: nystatin oral suspension or miconazole oral gel to affected corners of the mouth 4
- Evaluate and adjust dental appliances (dentures, braces) that may contribute to moisture accumulation 4
- Consider combination antifungal and antibacterial therapy if secondary bacterial infection is suspected 4
- Add 0.2% chlorhexidine digluconate mouthwash twice daily for moderate to severe cases 4
Denture Stomatitis
- Address poor oral hygiene and denture plaque biofilm, which are the primary causative factors 5
- Remove dentures overnight to reduce aspiration pneumonia risk 5
- Treat concurrent candidal infection with antifungal therapy 4, 3
Recurrent Aphthous Stomatitis (RAS)
- Assess for nutritional deficiencies (iron, folate, vitamin B12) before diagnosing idiopathic RAS, as correction may resolve symptoms 1, 6, 7
- For resistant cases, consider tacrolimus 0.1% ointment applied twice daily for 4 weeks 3
- Hydroxychloroquine may be effective for chronic ulcerative stomatitis that is refractory to standard treatments 8
Critical Diagnostic Pitfalls to Avoid
- Distinguish RAS from herpes simplex virus infection, which requires antiviral therapy rather than corticosteroids 1, 3
- Evaluate for herpes simplex virus before initiating corticosteroid therapy in immunocompromised patients 1
- Consider prophylactic antiviral therapy for immunocompromised patients with severe symptoms 1
- Treat any concurrent candidal infection before or during corticosteroid therapy 3
Supportive Care Measures
- Consume soft, moist, non-irritating foods that are easy to chew and swallow 2, 1, 3
- Maintain adequate hydration by drinking plenty of water 1
- Use sugarless chewing gum, candy, or salivary substitutes for oral dryness 2, 1, 3
- Apply lip balm regularly for dry lips 1
When to Reassess Treatment
- If symptoms do not improve within 7 days of topical therapy, escalate to more aggressive management 9
- If irritation, pain, or redness persists or worsens despite treatment, consider alternative diagnoses 9
- Inadequate pain control can lead to poor oral intake and treatment discontinuation, requiring prompt adjustment of analgesic strategy 1
