It is possible to bite your tongue in your sleep without having a seizure. One possibility is in association with bruxism (jaw clenching and/or tooth grinding while asleep), while another is in response to dreaming (sleep myoclonus, like when your leg or arm jerks spontaneously). There are other forms of myoclonus, such as a condition called familial nocturnal facio-mandibular myoclonus where the masseters (large chewing muscles) contract during sleep. Violent gasping breaths in association with sleep apnea may also result in tongue biting, especially if one's tongue is relatively large. There are cases where people even punch or kick in their sleep, a condition called REM sleep behavior disorder (RBD), which has an association with future development of Parkinson's disease and standard or Lewy body dementia. If you think you have bruxism, your dentist or primary care doctor can assist you; if you have any concerns about a neurologic cause, it may be best to visit a neurologist (nervous system specialist).
No need to repond to this.
Thank you for the Accept.
For bruxism, you might just try wearing a sports mouthguard at night (dentists make a customized version of this to treat bruxism).
