Tongue Biting Treatment: First Aid, Healing and When It Needs Stitches

Rinse the mouth gently with plain water to see what you are dealing with. Press a clean piece of gauze or cloth firmly onto the cut for ten minutes without lifting it to check. For a bitten edge, pinch the tongue gently between the cloth and your finger. Suck on something cold or hold ice wrapped in cloth against it to reduce swelling and pain.

The tongue bleeds a lot because it has a rich blood supply, so the sight can be worse than the injury. It also heals fast. Keep sitting up and leaning forward so you do not swallow blood.

Get seen the same day if the cut gapes open, is deep or long, goes right through the tongue, has a flap, or keeps bleeding after ten minutes of firm pressure. A split in the tip or edge that does not close on its own may need stitches, and early closure heals better. A broken tooth or something stuck in the wound needs care too.

Go to a hospital emergency department if bleeding will not stop, if you struggle to breathe or swallow, or after a heavy blow to the head or face. Our guide on what to do in a dental emergency lists what can wait and what cannot.

Small cuts and bites that stopped bleeding need no stitches. They heal well because of the tongue's good blood supply.

A small bite usually settles in a few days, and a larger cut in one to two weeks. Rinse with warm salt water after meals, eat soft, cool or lukewarm food such as curd, khichdi and dal, and avoid spicy, salty, sour, hot or crunchy food. Our guide on what to eat with a mouth ulcer has more ideas.

Widely available paracetamol, taken as directed on the label, helps most adults with the pain. Ask a pharmacist or doctor first if you have liver disease, drink alcohol regularly or take other medicines. Bitten tongues often form an ulcer afterwards. The guide on tongue sores explains when one is a worry, and blisters from heat are covered in burnt tongue treatment.

Repeated biting often has a local cause: a sharp or broken tooth, a high filling, a loose denture, a crowded or misaligned bite, or wisdom teeth. A dentist can smooth, repair or adjust these. Biting in sleep is common with teeth grinding, and a night guard may help, as discussed in the guide on a mouth guard for teeth grinding.

Biting during seizures, or sudden biting with other changes such as weakness or confusion, is a medical matter and needs a doctor. A bite that does not heal in three weeks needs examining, as the mouth ulcers page explains.
