Killing Canker Sores

  1. Mar 5, 2010 #1
    I have a pair right next to each other on the side of my lip where I bit it with both incisors. It's getting very hard to deal with it now.

    I tried to burn it to death with salt water, but it seems to have grown after I drank some water. The damn thing absorbs all the water out of my mouth.

    Does anyone know any methods of killing them?

    Just pickup some meds at walgreens or cvs

    Do you know anything that is particularly effective?

    A good and cheap remedy is to mix drug-store hydrogen peroxide 50:50 with water and apply it with a cotton swab. My father loves fresh garden tomatoes, and he'll overload on them until he starts getting canker sores. Using the peroxide wash doesn't cure the sores, but it helps prevent infection so they will heal faster.

    Sounds like a plan...except that it would probably taste nasty. I'll give it a try later.

    I do the same, except I don't dilute it. Burns a bit, but the sore seems to start healing within a day. I've had sores last for days, and when I do this its clears up quickly.

    They have special oral meds for mouth sores, with the active ingredient being benzocaine. It works pretty well for a short while. Should be available at any drug store. Oil of cloves will also help, it should be available over the counter too.

    go to the doctor. oral health is part of overall health. why would you let yourself to experience that much discomfort. GO TO THE DOCTOR and get it checked out. All the biting and ripping into the sores does expose it to infection. There is no reason not to go to the doctor.

    It'll probably heal by the time I get in a few weeks from now.

    dude, if you told your primary care physician your problem, they will see you immediately. how old are you? You seem young in terms of life experience. I do not mean it in a bad way, but doctors do not put you on hold for several weeks while you suffer.

    I'm 19, and I guess I am a little short.

    I mean it just takes a bit to get an appointment.

    Walk-in clinics?

    Dealing with sores in the mouth normally aren't that serious though. I'd suggest just making sure it's clean and don't irritate it. However if it starts to hurt a lot for days at a time or it is 'large' then you definitely should go to see a doctor. There isn't really a lot of tissue in your mouth and sometimes these sores can go down to the bones which can be dangerous to your overall health.

    the key is health insurance. Do you have health insurance? go to the doctor. i like the walk-in-clinic idea in case you cant get an appointment quickly.

    OK dude, that's it from me. No more advice. if this thread keeps going, then it will cause you to start dwelling in your misery and i will not participate in this circular reasoning. Good luck and bye (I'm not trying to be mean but enough. its simple, you hurt you go to the doctor).

    I live in Canada, and I do have insurance. It's not an issue.

    I was looking for a way I could speed up the healing.

    So I guess I'll just keep it as clean as I can.

    that would be inconvenient, i hurt all the time

    Try some of the amino acid L-lysine, most drug stores carry it. My Father swears by coating the sore with sea salt, it stings a bit, but does seem to dry it out.

    I am a huge wuss, so rather than feel like my mouth is on fire, I buy Orajel from the drugstore. It's a numbing agent that at least gets rid of the pain. Be careful though - the stuff tastes HORRIBLE, so do not accidentally swallow it. Also, be careful in application of it, because it DOES work - don't end up numbing your whole mouth or tongue accidentally :)

    I HATE Canker sores! I have 2 right now where i bit my lip...(Pretty much what happened to the OP here). Also, i get1-2 Cold Sores a year usually, and i guess the Canker sore on the upper part of my bottom lip did something to cause a Cold sore to pop up pretty much on top of it...sucks so bad. I have some meds though, hopefully it will make it much better.

    I seem to have canker sores in my mouth more often than i dont. =(

    I rarely get canker sores, but when I feel one starting, I put neosporin on it and it disappears without fully forming. Of course neosporin is not for use inside your mouth, but just saying...
