My 5 year old son frequently bites his teeth in night and also bites something else if whatever he gets to bite, if he didnt get anything he bites his tshirt and it will be wet. pls tell me is this any symptom of a disease.

A. Cluttering of the teeth can be associated with worms in the stomach so for that you can do deworming but if your child is so desperate to bite it could be due to some deficiency in case it is better to check with Dr and start with necessary supplement required
