Back of mouth burning
Burning at the back of the mouth can come from irritated mucosa, reflux, dry mouth, infection, nerve sensitivity, or a dental source.
The short answer
The area includes the soft palate, tonsillar region, tongue base, throat entrance, and gum behind the last molar. Burning is a symptom, not a diagnosis.

Hot food, acid, reduced saliva, fungal overgrowth, medicines, a sharp tooth, or an erupting wisdom tooth can irritate these tissues.
What can you do to ease irritation in this area?
Avoid hot, spicy, acidic, and alcoholic products, drink water, and note links with meals, medicines, mouth products, or lying down.
When does mouth burning need prompt dental care?
Seek care for swelling, fever, pus, a persistent ulcer, neck lump, swallowing difficulty, or breathing difficulty.
What should you ask about burning at the back of your mouth?
Ask which tissues are involved and whether dry mouth, reflux, infection, or a dental edge is likely.
