[|Human|] My three year old son fractured his tooth across the nerve about a year ago, which lead to necrosis of the tooth. I have realized lately he has been chewing excessively on his clothing and blankets. His gums looks healthy, but I am very concerned there can be an internal issue with his tooth. I took him to an oral specialist about 8 months ago and they stated there was no infection and they would leave the tooth.
[|AI|]  Hello, Thanks for posting on Chat Doctor, Your son might not necessarily be suffering from a tooth problem (as most of the time will be painful and rather make him avoid contact with hard objects) but could be suffering from a neurological or psychosocial problem. There are several diseases conditions that could affect muscle and cause them to perform involuntary movements thus excessive chewing. In chewing this is most likely going to be due to a behavioral problem, and you can guide him into stopping. You will need to see a pediatrician to assist you with your child. Hope this helps
