What causes bad breath and teeth grinding at night?

Patient's question:

Main symptoms: I am very thin and no matter how much I eat, I don't gain weight. I also grind my teeth when taking afternoon naps. Could it be that I have worms in my stomach?

Doctor's answer:

During deep sleep, the sound of upper and lower teeth grinding occurs, which is commonly known as bruxism. Napping bruxism is caused by the sustained contraction of the jaw muscles, and the activity of these muscles is controlled by the trigeminal nerve. Therefore, any factors that can affect the trigeminal nerve and jaw muscles can lead to napping bruxism. It is more common in children and is associated with various factors:
1) Excessive mental excitement and tension before falling asleep, such as excessive play, being overly excited or fatigued, or being startled, leading to nighttime bruxism.
2) Intestinal parasitic diseases Hookworms particularly thrive in children's intestines after they fall asleep and excrete various toxins. Abdominal pain around the navel, restlessness during deep sleep, and consequently, bruxism.
