Traumatic Oral Ulcer Management

Clinical Presentation and Diagnosis

The American Academy of Dermatology suggests that a grey covering on a swollen lip ulcer one week post-trauma is most consistent with Morsicatio labiorum, which can be complicated by secondary bacterial or fungal infection 1

The British Association of Dermatologists recommends applying white soft paraffin ointment to the lips every 2 hours to protect the ulcerated surface and maintain moisture 2
The British Association of Dermatologists suggests using antiseptic oral rinse with 0.2% chlorhexidine digluconate mouthwash (10 mL twice daily) to reduce bacterial colonization 2
The British Association of Dermatologists advises applying benzydamine hydrochloride oral rinse or spray every 3 hours for anti-inflammatory effect and pain control 2

The British Association of Dermatologists recommends cleaning the mouth daily with warm saline mouthwashes using gentle sweeping motions to remove debris without causing additional trauma 2
The Infectious Diseases Society of America suggests avoiding alcohol-containing mouthwashes as they cause additional pain and impair healing 1, 6

The American Cancer Society recommends eliminating all irritating foods, such as tomatoes, citrus fruits, hot drinks, spicy foods, hot foods, raw foods, and crusty foods, until healing is complete 1
The British Association of Dermatologists advises consuming only soft, moist, low-acidity foods if tolerated 2

The British Association of Dermatologists suggests using viscous lidocaine 2%, 15 mL per application, as a topical anesthetic before eating for inadequate pain control with benzydamine 2

The Infectious Diseases Society of America recommends watching for signs of complications, such as pain disproportionate to injury, spreading erythema, fever, or lymphadenopathy 6
The American Academy of Dermatology advises evaluating treatment response within 2 weeks and reevaluating for correct diagnosis if no improvement is seen 3, 4

The Infectious Diseases Society of America suggests not using first-generation cephalosporins, macrolides, or clindamycin alone if systemic antibiotics are needed, as these have poor activity against oral polymicrobial flora 6
The British Association of Dermatologists recommends not using petroleum-based products chronically on lips as they promote mucosal dehydration and create an occlusive environment that increases secondary infection risk 4
