How To Cure and Prevent Mouth Ulcers?

May 9th, 2010 · 8 Comments ·


I have been suffering from mouth ulcer for couple of days last week. It started after I accidentally bit my inside cheeks when I ate too fast. The wounds later become ulcer. Worse, when these few ulcers combined to be a single half-inch diameter big ulcer, the pain was even worse. I felt the pain when I talked, ate and even when I brushed my teeth.

Wait, before I write more, what is mouth ulcer?

What Is Mouth Ulcer?
Mouth ulcer is also known as canker sore or apthous ulcer. It is ulcer with red rim that form inside the lips or cheeks or even tongue. They burn and tingle, especially when you eat spicy or acidic food.

Based on what I found, the process causing the sores in unknown. However, few possible causes are:

  1. When you inadvertently bite your tongue or the inside of the cheek, the wound could become an ulcer.
  2. It could be also a symptom of lacking nutrients and therefore affecting immune system.
  3. Emotionally stressed
  4. Food sensitivities may trigger ulcers too. Foods that cause this problem include acidic fruits and chocolates.

How To Cure Mouth Ulcer
Good news is that mouth ulcer rarely cause complication. Most heal naturally with time (1 to 2 weeks) without medication. The only possible complication which mouth ulcer may cause is bacterial infection. In rare cases, an infected ulcer may infect your teeth.  Here are few ways to cure mouth ulcer:

  • Rinse mouth with warm salt water several times a day.
  • Chinese rely more on herbs in the treatment of cranker sores.
    • Some herbs contain tannins (tannic acid) which have wound healing properties. Calendula tea, goldenseal tea or even the regular beverage tea provide rich supply of tannis. You can gargle tea to heal the mouth ulcer.
    • Based on my personal experience, I highly recommend Watermelon Frost. I used it ever since I was small. This gray powder is made from watermelon rind (the white outer layer) as the main ingredient and other Chinese medicinal materials. It has a unique curative effect.

  • Tomatoes juice can be helpful too for the treatment of mouth ulcers.
  • You can try using brown sugar. Before you go to bed, take a pinch of brown sugar and press it into the sore. Brown sugar suck the acid out of the sore and therefore allowing it to heal.
  • When you have mouth ulcer, avoid spciy food, hot tea and coffee. Some people find that certain food such as peanut, coffee or chocolate can make them more likely to get ulcer. If you know that particular food provokes an ulcer, take note and avoid eating that food until your ulcer have completely healed.

How to Alleviate the Pain of Mouth Ulcer

  • Some over-the-counter topical gel like Bonjela (popular in the UK) and Cankermelts may help reduce the pain of ulcers.
  • You can also numb the pain with ice cube. However, it will hurt initially. After a while, the pain will be numbed temporarily.
  • Another method for temporary pain relief is to gargle with mouth wash. Again, you may scream for pain at first, but it is relieving afterward. If your mouth ulcer is caused by dry mouth, alcohol-based Listerine may not be helpful. Use mouth wash specially made for dry mouth such as Biotene or Oasis.


How To Prevent Mouth Ulcer

  • If you are prone to canker sore from time to time, avoid biting or hurting the inside of your mouth. Use softer toothbrush, rectify the position of your tooth (by wearing braces) and avoid hard sharp-edged food.
  • If stress is the root cause, exercise and relaxation may be the long-term answer. Yoga is highly recommended.

    Also, taking the supplement L-Lysine dramatically reduces the pain and speeds the healing! 1,000mg 2x per day.

    yea i’m a big fan of watermelon frost too. not only it is able to cure the ulcer, you can use it even when you have discomfort in the throat.

    there’s another cure to the mouth ulcer that you didn’t really touch on. please note that it is for extreme measures only and to people that either like pain or have really high pain threshold. the method is simply, just put a pinch of salt on the ulcer itself. throbbing pain and headache usually follows after a few seconds and then you’ll get numbness on the ulcer. it usually takes me about 3 days to heal if i put salt on it every night before i head to sleep.

    I used to get them all the time. Many years ago I found out that any cut inside my mouth would usually end up in an ulcer. They hurt so bad that I began looking for anything that would help. I’ve tried numerous over the counter medications but nothing seemed to work. Finally I found my own method for relief. The two things that seem to help me are:

    1. I brush carefully. If I don’t, I will inevitably slip and the handle of the toothbrush will cut my gums. If that happens I can count on getting an ulcer.

    2. If I do end up with an ulcer, I wash my mouth immediately with hydrogen peroxide (Don’t Swallow). I continue to rinse my mouth over the next several days several times a day and it seems to work for me.

    I am 63 years old now and i have suffered from mouth ulcers since i was a much younger person. A few years ago i began to get very large ulcers in my mouth which were so sore my mouth swelled up at the side of my cheek inside my mouth and even larger ulcers appeared under my tongue which made it hard to eat. My dentist later discovered i had a large abcess under one of my crowns, the crown had to be removed and the stump which held the crown was also taken out. She said good hygiene was a must regular brushing etc but i always take care of my teeth anyway, i have been told to gargle with warm salted water but i found this was not really helpful Recently i have had a large painful ulcer inside my bottom lip and i went to Suprer drug and brough a new product Bonjela complete plus a liquid which you apply with a dspatula when needed. I have only used it a few times and it has taken away the pain and soreness away already. It is expensive to buy £7.99P but it normally covers about 100 applications. I think mouth ulcers are horrible especially if you get them often and the pain when eating certain foods puts you off of eating and drinking as the stinging is a miserable experience.

    For Canker sores or fever blisters take L Lysine . It is a natural vitamin, and I am a former dental assistant, and I;ve done it for years and now I have none. IT has now been wriitten in the JADA (Journal of American Dental Association) recommending it. IT is a B Vitamin and if you have an over amount it leaves the body in the urine so you cannot take too much of it.
    If you have a bad one and it hurts a lot, I recommend crushing one of the L Lysine tablets with a spoon or something and put the crumbs on the actual sore. Before this take 2 or 3 of them with water. You can feel the pain easing right away and by morning it is already better than it ws. If it is still bothering you take a couple more, and after it is gone just take one tablet a day. They are very cheap,, and can be bought almost anywhere like Walmart or grocery, or drug stores.
    I had a friend who took Lysine for years and stopped because she never had one but went on a trip to the Bahamas and got sun burned and came back with 5 fever blisters on her bottom lip, I said I thought you took L Lysine and she said, Oh I did but I never had them so I quit. But I won’t do that again. She was pretty miserable. Good luck. C

    I have a seriosly painful mouth ulcer under my lip (but inside) you know right next to the peice of skin that attaches your lip to your gum at the bottom and it also really hurts my jaw.It hurts like crazy but i have got a remedy that im using its not the greatest but it kinda works.What i do is i gargle water for a minute or so then i spit it out then i swerl my mouth out with water spit that out.Then i brush my teeth swerl my mouth out again.use mouth wash gargle that spit it out,then i swerl out my mouth again.I know it may take upto 5 minutes but it is worth it!i do this in the morning and at night it also realeves the pain and if your ulcer is in the same place as mine then it makes it more comfortable for you to pull your lip down and have a look at it.Oh yeah and one more tip swerl you mouth out beacuse if you get food stuck under you lip where the ulcer is then it might get infected and then you might have to go and see your dentist.

    Hope this works!!!
