Why do people grind their teeth while sleeping?

Patient's question:

No

Doctor's answer:

First, there are parasites in the body. Parasites secrete some harmful substances, which affect the autonomic nervous system. Take 2 parasite-expelling pills.
Suggestions:
The second reason is mental tension and excessive liver fire, mainly due to improper daily diet, consuming too much fried, spicy, and refined foods, leading to the accumulation of internal heat and toxicity. It is recommended to use traditional Chinese medicine to clear heat and reduce fire.
