Best Gel for Mouth Ulcers

For treating mouth ulcers, Gelclair mucoprotectant gel is the best first-line topical treatment, as it provides a protective barrier over ulcerated surfaces and offers effective pain relief. 1, 2

First-Line Treatments

Barrier Protectants

  • Gelclair mucoprotectant gel applied three times daily forms a protective coating over ulcerated surfaces, reducing pain and promoting healing 1, 2
  • White soft paraffin ointment should be applied to the lips every 2 hours if they are affected by ulcers 1, 3

Topical Corticosteroids

  • Betamethasone sodium phosphate 0.5 mg dissolved in 10 mL water as a 3-minute rinse-and-spit preparation four times daily 1, 2
  • For localized ulcers, clobetasol propionate 0.05% mixed in equal amounts with Orabase can be applied directly to the affected areas daily 1, 2

Pain Management

  • Benzydamine hydrochloride oral rinse or spray should be used every 3 hours, particularly before eating 1, 4
  • For more severe pain, topical anesthetic preparations such as viscous lidocaine 2% can be applied up to 3-4 times daily 1, 5, 6
  • Benzocaine-containing products can be applied up to 4 times daily for adults and children over 2 years of age 7, 8

Oral Hygiene Measures

  • Clean the mouth daily with warm saline mouthwashes to reduce bacterial colonization 1, 3
  • Use antiseptic oral rinses twice daily, such as:
    • 1.5% hydrogen peroxide mouthwash (e.g., Peroxyl) 1
    • 0.2% chlorhexidine digluconate mouthwash (can be diluted by up to 50% to reduce soreness) 1

Alternative Topical Treatments

  • Topical diclofenac 3% in 2.5% hyaluronan provides sustained pain relief for up to 6 hours, significantly better than hyaluronan gel alone or viscous lidocaine 9
  • Topical 5-aminosalicylic acid (5-ASA) 5% cream applied three times daily can reduce healing time and discomfort 10
  • Vitamin B12 ointment has shown effectiveness as an analgesic treatment for aphthous ulcers 11

Treatment for Secondary Infections

  • If candidal infection is suspected, treat with:
    • Nystatin oral suspension 100,000 units four times daily for 1 week 1, 2
    • Miconazole oral gel 5-10 mL held in the mouth after food four times daily for 1 week 1, 2

Second-Line Treatments for Refractory Cases

  • Tacrolimus 0.1% ointment applied twice daily for 4 weeks 3
  • Intralesional triamcinolone injections (weekly, total dose 28 mg) in conjunction with topical clobetasol 2, 3
  • Systemic corticosteroids for highly symptomatic or recurrent ulcers 2, 3

Common Pitfalls and Considerations

  • Ensure proper diagnosis of the type of mouth ulcer before initiating treatment 3
  • Children under 12 years should be supervised when using topical anesthetics 7, 5
  • Topical anesthetics may interfere with the gag reflex, so caution patients not to eat immediately after application 5, 6
  • For patients with recurrent aphthous ulcers, consider underlying systemic conditions that may require additional treatment 3
