I keep biting my tongue/cheek in my sleep?

Check with dentist: Tongue, cheek biting indicates problems of occlusion, the way teeth fit together during function such as eating and swallowing. It is the swallowing where teeth of opposing arch occluded against each other and where tongue and cheek biting may occur. Treatment included occlusal adjustment (selective grinding) and/or biteguard (in extreme case).

I often wake up at night from pain caused by biting my tongue in my sleep, how do I stop this?

Many reasons: Have your dentist look at your bite. Did you have some new crowns/fillings done, new denture or a set of teeth, do you have an enlarged tongue? An enlarged tongue could be due some diseases like amyloidosis or sleep apnea. Is there a lesion or mass in the tongue. Sometimes a mouth splint can help.

What causes biting tongue in sleep. I wake up with bite marks on both sides of tongue. How can I prevent this? I am sleeping/unaware when I do this.

What causes biting tongue in sleep. I wake up with bite marks on both sides of tongue. How can I prevent this? I am sleeping/unaware when I do this.

REM Sleep Cycle: In deeper stages of sleep, the muscles of the eyes (rem) are active, as well as the muscles of mastication. That's why some people clench and/or grind their teeth at night. If you are an "active" bruxer, you can "nip" the sides of the tongue. Once swollen from the injury, it is easier to bite again. Be careful. Talk to your dentist about a night guard or Elavil (amitriptyline) 10mg to decrease bruxing in dreams.

What to do if I'm biting the side of my tongue/cheek in sleep?

What to do if I'm biting the side of my tongue/cheek in sleep?

Cheek biting: If there is a change in the moisture in the mouth the cheek can stick to the teeth and be pulled into the chewing surfaces. Also have you been evaluated for sleep apnea or night time grinding of your teeth (bruxism). You may be sucking the cheek (s) into the teeth at night or grinding side to side and catching the cheek between your teeth. Avoid alcohol containing mouth rinses before bed.

Mouth breathing: It is not uncommon with osa that an individual may have nasal airway insufficiency and thus breathe primary through their mouth. This dysfunctional breathing pattern may lead to an enlarged tongue and at night during sleep, nocturnal bruxism continues except rather grinding and clenching on the teeth, the enlarged tongue takes the brunt of the damage.

Can biting one side of your tongue when you sleep, to the point where it starts bleeding, be a sign of having had a seizure?

Can biting one side of your tongue when you sleep, to the point where it starts bleeding, be a sign of having had a seizure?

Evalutation needed: You could have sleep bruxism which is a sleep disorder. I would suggest a sleep study at a sleep lab. They can confirm or rule out sleep bruxism or other sleep disorders.

Oral trauma: As a Family Doc, I look for common things & dangerous things (not always same). So common reason to bite yourself while asleep is (bad) dreams etc. But dangerous reason is seizure, especially if accompanied by incontinence (loss of bowel or bladder control). In States, you can purchase w/o prescription numbing agents to relieve gum pain but I can't speak to what's available in UK. Please see ur GP

Possibly: There are a number of possible causes for bruxism as well as different modalities of treatment that may or may not involve a mouth guard. You need to have a thorough dental exam with the appropriate studies to determine possible causes of your bruxism. If you do require an appliance there are different types of appliances that can be utilized that may allow you to sleep comfortably.

Pain in side of tongue only when asleep. Nerve pain/ stabbing pain awakens me. Near sore that has no pain. Not from biting - nerve explosion - cause?

Get a Diagnosis: You need to see a dentist for diagnosis and referral. This could be serious. A painless sore with shooting pain could be an abscessed tooth with infection spreading to the tongue and if untreated to your neck or brain. It could be a tumor, possibly cancer. No one can tell without examining you so see a dentist today.
