Clinical Information

• A mouth sore, or oral ulcer, is a painful lesion that can occur inside the mouth on the lips, cheeks, gums, tongue, or palate.
• Common causes of mouth sores include trauma (e.g., biting, dental work), viral infections (e.g., herpes simplex), and aphthous ulcers (canker sores).
• Assessment involves examining the sore's location, size, appearance, and duration, along with patient history.
• Sometimes, diagnostic tests, such as viral cultures or biopsies, may be needed to determine the underlying cause.
• Treatment options vary depending on the cause and may include topical medications, oral rinses, or antiviral drugs.
• Pain management is an essential aspect of care, often achieved with topical anesthetics or over-the-counter pain relievers.
• Patients should be educated on oral hygiene and encouraged to avoid irritants like tobacco and spicy foods.
• Follow-up is essential to monitor healing and identify any recurrence or persistent sores.
• Healthcare practitioners should consider underlying systemic conditions in cases of recurrent or atypical mouth sores.
• Referral to specialists, such as oral surgeons or dermatologists, may be necessary for complex or refractory cases.
