I have been bitting my tongue in my sleep on the same side i have been having a tooth problem?

See dentist: this may be your body's subconscious attempt at correcting the irritation (tooth problem).

Nocturnal bruxism: is the medical term for clenching or grinding teeth during sleep. See your dentist for evaluation and night guard fabrication to protect your teeth and your tongue.

See Dentist: Have your tooth problem fixed. Have your bite evaluated. Reshaping teeth or fabrication of a tongue guard appliance may help. See Dentist.
