Which term describes involuntary grinding of the teeth?

• A. Bruxism
• B. Crown
• C. Decalcification
• D. Exfoliate

Answer: (A)

Bruxism is the term used for involuntary grinding (or clenching) of the teeth, often occurring during sleep or in response to stress. This habit causes wear on the chewing surfaces, can lead to tooth sensitivity, and may contribute to jaw muscle fatigue or temporomandibular joint discomfort. The other terms describe different dental concepts: a crown is a restoration that covers a tooth; decalcification is the loss of minerals from enamel due to acidic exposure; exfoliate refers to shedding of teeth (such as shedding primary teeth), not grinding.
