What is trismus?

Explanation:
Trismus is limited opening of the mouth due to spasm or dysfunction of the muscles of mastication. The defining feature is the restricted ability to open wide, which is what the item is asking you to identify. It’s not merely pain in the jaw, swelling of a salivary gland, or numbness of the tongue—those are separate signs or conditions. In dental contexts, trismus can arise from muscle spasm after procedures, infection, trauma, or other jaw‑related issues, and it directly impacts how you access the mouth for exams or anesthesia.
