Why does a mouth ulcer hurt so bad?
4 doctors weighed in across 2 answers
Nerve endings: The mouth has a highly dense area of sensory nerve receptors for pain in the tissue and when you have an ulcer they are exposed and can be stimulated easily.

Exposed nerves: An ulcer in the mouth is painful due to the exposure of nerves in the ulcerated tissue.
