Evidence‑Based Management of Traumatic Lip Nodules

Assessment and Identification of Trauma Source

Identify and address the underlying cause of chronic lip biting as the first step in management. 1
Evaluate for sharp tooth edges, malocclusion, or ill‑fitting dental prostheses that may perpetuate repetitive trauma. 3

Inspect the oral mucosa daily to detect changes in size, colour, or signs of infection. 2

Use a soft‑bristled toothbrush after meals and before sleep to maintain cleanliness without adding trauma. 4
Rinse with an alcohol‑free mouthwash at least four times daily for about one minute to reduce inflammation and prevent secondary infection. 4
Apply lip balm or sterile petroleum jelly to keep the lips lubricated, but limit use to ≤ 2–3 weeks to avoid mucosal dehydration and increased infection risk. 4
Maintain adequate hydration by drinking sufficient fluids to keep the oral cavity moist. 3

Cease smoking and alcohol consumption during the healing period to promote optimal tissue recovery. 4
Avoid spicy, hot, acidic foods (e.g., tomatoes, citrus), hot beverages, and hard or crusty foods that could further traumatize the lesion. 3

Proceed to excisional biopsy when the patient reports significant discomfort despite conservative measures. 3

Do not use petroleum jelly chronically (beyond 2–3 weeks) because prolonged occlusion can cause mucosal dehydration and raise infection risk. 4
