What to Do If You Cut Your Mouth or Tongue

mouth cut

Mouth cuts always get infected

by James Hubbard, M.D., M.P.H.

You’re camping in a remote part of Alaska. The helicopter that brought you in won’t be back for days. You slip and hit a rock. Your front tooth cuts through your lip or cuts your tongue. What do you do? How do you treat a mouth cut or a tongue cut when no medical help is around?

Actually, a mouth cut is one of the easier cuts to treat. Granted, it’s painful and tends to get infected. But we don’t stitch the mouth, inner lips, inner cheeks, tongue, or gums unless it’s big, gaping wound or it won’t stop bleeding.

Note: If the cut involves the outer lip or face, click here.

So you’ve got an inner lip cut, tongue cut, whatever mouth cut you choose, and there’s no help around. Here’s what to do:

1. Clean the cut.

  • Pick out any obvious debris.
  • Irrigate the cut with water. Swish the water in your mouth, or squirt it into the cut.

2. Stop the cut from bleeding.

  • Stuff a clean cloth between the cut and your gum or teeth. (No cloth? Squeeze, pinch, apply pressure of some sort. Ten minutes should do it.)
  • Ice the cut for five to ten minutes, if possible. You can use the ice as part of the compression inside the mouth or wrap cloth around the ice and use it on the outside.

3. Start an antibiotic, if available.

  • You can expect any mouth cut to get swollen, painful, and infected. The mouth is full of bacteria. There’s no way to keep the wound sterile.

4. Eat soft food, don’t chew on that side, avoid salty foods (they make the cut sting).

 

And that’s all you can do. That’s all medical personnel do unless the cut is gaping badly or won’t stop bleeding. Then we’ll put in stitches, but only then. The reason is twofold:

  1. Sutures are foreign material that bacteria can attach to, so the infection may be worse.
  2. Infected wounds need to be able to drain if bacteria and pus build up. Otherwise you may get an abscess (trapped bacteria and pus).

Even if you partially tear the tongue frenulum (that little piece of skin that attaches your under-tongue to your lower mouth) or the lip frenulum (connecting the upper lip to the gum), don’t worry. Just follow these instructions, and it’ll grow back together unless it’s a really bad cut.


What to Do for Mouth Cuts on the Outside

If the outside lip or face is cut, clean that, and tape it like you would any other cut. (But keep the inner mouth/tongue wounds open.)

If the outside colored part of the lip is cut, that’s more of a problem. You want it to grow back straight, so a doctor should see that ASAP. If that’s not possible, tape it back as straight as you can, keeping the colored edge as even as you can.

    i cut my tongue while eating a pear drop and it stings what shall i do it was bleeding alot

  • Jess

    I was trying to pick something out from between my teeth and my nail slipped and I cut the upper gum and inside lip. I was bleeding a lot and now has gone white (3 days later) and hurt a lot. It looks like a long thin canker sore. Should I go see a doctor or will it heal without antibiotics? Also is there anything for the pain? It hurts a lot all the time. Thank you

      In general, if it’s getting more swollen, red, or painful, you should see a doctor. Meanwhile, maybe some warm water, orajel, or clove oil could ease the pain and/or some ibuprofen. acetaminophen, or naproxen.

    This is it

  • jaymee

    My name is jaymee and I was playing softball and I bit my tounge it was bleeding and its not now but theres a cut what should I do?

    • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

      I can only give you the general information on the post. You, or someone you get to check you, has to make the final decision on what to do.

      • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

        And, in the end, the decision will probably be which is better, leaving it alone and causing a bigger scar, or closing it up. Yours is right on the border of size that it could go either way.

    Hello. So I read a lot of your answers. But I gave to ask for myself. My 19mo boy fell while playing with a plastic tube in his mouth, the tube jammed under his tongue and seed to cut or injure in some way the underneath/possibly his frenulum…I’m not sure,as he won’t let me get a clear look at it. But it’s really ugly poking under there. It bled pretty bad. Although it did stop bleeding. He can drink his bottle/milk…and refuses to eat anything.(understandibly) I’m worried…will he be ok?

    • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

      Richelle, he should see a doctor. There’s no way I could predict if he’s going to be ok without an exam. And the post is suggestions for when a doctor is not an option.

        I bit my tongue and I’m on blood thinners and it’s been bleeding out for 2 hours pretty bad what should I do to stop it

          If you’re on warfarin and it’s bleeding more a lot, you should see a doctor tonight, or call your regular doctor.

    Hi My 1 year old son was fall down and had a cut around 1-1.5 Cms, doctors advised no need to stich , it will heal up, i am wondering, will it be join perfectly and how much time it will take? ur answers are very much appreciated .

    • http://thesurvivaldoctor.com/ James Hubbard, MD, MPH

      A cut in the mouth or tongue usually takes about a week to heal. All wounds have scars of some sort but, unless it’s a big, gaping wound, it should heal fine.

      Depends on the size and the depth of the wound. Have you parents look at it.
