What should I do if my jaw cramps when yawning?

Jaw cramping during yawning may be caused by the following reasons: 1. Muscle spasm: Excessive mouth opening during yawning can overstretch the masticatory muscles, leading to muscle spasms that manifest as jaw cramping. 2. Calcium deficiency: Calcium ions are essential for maintaining normal nerve and muscle function. Low calcium levels may increase neuromuscular excitability, making cramps more likely. 3. Temporomandibular joint (TMJ) issues: Prolonged chewing of hard foods or frequent yawning may cause inflammation in the temporomandibular joint area, resulting in jaw cramping or pain during yawning. To alleviate this condition, consider the following measures: 1. Heat application: Apply a warm towel or hot water bottle to the jaw area to improve blood circulation and relieve pain. 2. Calcium supplementation: Ensure adequate daily intake of calcium-rich foods such as milk and soy products. 3. Avoid excessive mouth opening: Be mindful of limiting the extent of mouth opening while yawning to prevent overextension. If cramping symptoms persist or worsen, it is advisable to seek medical attention promptly.
