Sore sensitive mouth
A sore, sensitive mouth can result from trauma, infection, dry tissues, ulcers, irritation, or a dental problem that needs examination.
The short answer
A sore, sensitive mouth can result from trauma, infection, dry tissues, ulcers, irritation, or a dental problem that needs examination. This symptom can involve the cheeks, tongue, palate, gums, or throat-side lining.
Which areas can mouth soreness affect?
This symptom can involve the cheeks, tongue, palate, gums, or throat-side lining. The location, appearance, duration, and triggers help separate a bite injury from an ulcer, thrush, tooth infection, or chemical irritation.
What can you do to soothe a sore mouth?
Choose cool, soft foods, drink water, avoid tobacco, alcohol, very spicy foods, and sharp edges, and brush gently with a small soft brush. Do not scrape a coating or place aspirin directly on the sore.
When should a persistent mouth sore be examined?
See a dentist or clinician for a sore that persists, repeatedly returns, spreads, bleeds, forms a hard lump, or comes with fever or neck swelling. Seek urgent help for breathing or swallowing difficulty.
What details should you share about your sore mouth?
When did it start, where exactly is it, and is there a visible ulcer, coating, swelling, broken tooth, new medicine, or recent bite? Ask what examination or swab is needed.
