What is tooth grinding usually attributed to?

  1. Poor dental alignment

  2. Calcium deficiency

  3. Stress

  4. Excessive fluoride

The correct answer is: Stress

Tooth grinding, also known as bruxism, is most commonly attributed to stress. While the other options could potentially contribute to tooth grinding, stress is the primary cause. Poor dental alignment may cause discomfort or strain on the jaw muscles, leading to tooth grinding, but it is not the main factor. Calcium deficiency may affect the strength and health of the teeth, but it is not a direct cause of tooth grinding. Excessive fluoride can lead to tooth sensitivity and damage, but it is not a common reason for tooth grinding. Ultimately, it is important to manage stress levels to help reduce the likelihood of tooth grinding.
