Canker Sore Remedies

I am 29 and have suffered since I was little. I get them once a month if I do not take preventative measures. The good bacteria found in natural yogurt is what works for me. My mother used to make it homemade, because it worked so well. Later we found, acidophilus capsules. This is the good bacteria in a little pill. Works wonders.


When I have an outbreak, I use Anbesol, this is what is used on baby gums when they are teething. It hurts for 1 millisecond, but helps to numb the area.

I have a couple of tips that no one has mentioned yet. You can get rid of strep using natural remedies. We have done it use natural antibiotics with no side affects as with antibiotics. Next the best thing we have found for canker sores is colloidal silver. It is a natural antibiotic and should not be taken for more then 10 days. Hold it in your mouth for as along as you can and then swallow. Do several times a day. This will also boost your immune system. Hope you get relief. (01/14/2008)

Too much sugar candy can cause canker sores. I take a Q-tip, wet it, dip into baking soda and put onto canker sore and hold it there. The Q-tip helps to keep it in one spot, the soda helps neutralize the acid in the sore. Smarts something nasty, but works wonders to clear it up. (01/14/2008)

My son's dentist said to avoid oranges and orange juice when you feel one coming on or have one. I used a Listerine strip on a canker sore and it made it numb and heal faster than anything I've tried. (01/14/2008)

As Elizabeth says take 500mg Lysine every day. I used to get them every few weeks. Lysine is an amino acid that gets depleted from the body. You must take it every day. If one should start, take 500mg twice a day. They are so painful you can't eat much of anything you're so afraid of getting food near it.

I've read a lot or remedies, but only a few posts discuss causes and preventions.

No one in my family can take vitamin C supplements, and we are all very sensitive to citrus, tomatoes, pickles, margaritas, and peppermint candy. My problems with mouth ulcers stopped once I realized that I broke out only after eating oranges, mangoes, grapefruit, pineapple, etc. Tomatoes which are also used in chili and pasta dishes make my mouth sore and gums puffy. My tongue and mouth will actually start burning while I'm eating these foods, especially citrus.


Another major problem is flavored toothpastes, especially spearmint flavors and the Scope type of pastes. I switched to plain unflavored Crest and my gums immediately stopped bleeding. I eat acidic food in extreme moderation. For example, if I eat an orange, I definitely avoid tomatoes on my sandwich. I ate chili for dinner last night and again for lunch today, and now my mouth is sore. The tomatoes and that darned margarita got me again. (01/15/2008)

I have been a canker sore sufferer for most of my life and it has only been in the last few years that I've found anything that really works for me. Mainstream medical science doesn't pay much attention to cankers. Most doctor's I've encountered say, "it's nothing to worry about, just wait a week or two". Easy for them to say.


For me, taking B-vitamin supplements and swishing with Listerine help the most. This definitely reduces the intensity and duration of the sores I get.

Also, my anecdotal experience is that prescription antibiotics work really well. A few years ago I had a sinus infection and the doctor prescribed some type of antibiotic. It just so happened that I had a bad canker sore on the inside of my lower lip at the same time. That canker healed faster and with less pain than any other significant canker I've ever had. Also, the cycle of healing was much different. The canker just skipped several of the phases they normally go through during the healing process. (01/26/2008)

For all of you that can not take vitamin C; try Ester C which is Calcium Ascorbate and non-acidic. The most common vitamin C is Ascorbic Acid which for some can cause irritation. (01/29/2008)

To kill the pain immediately and help clear it up, get some Pepto or Maalox and use a Q-tip to dab it on the ulcer. It feels better instantly and helps the sore heal. Also, tea bags and salt help, but they may hurt. (02/04/2008)

The trick is to use Canker Cover, I bought them at Walgreen's. It is a little hard to apply, but leaves a gel substance within 30 minutes. They advertise that it usually only takes one treatment. We will see. (03/11/2008)

Canker Sore Remedies


  • Eat plenty of salad with raw onions. Onions contain sulfur and have healing properties.
  • Diet should include yogurt and other soured products, such as cottage cheese, and buttermilk.
  • Prepare a solution by adding 2 oz hydrogen peroxide, 2 oz water, and 1 tsp each of salt and baking soda. Rinse the mouth with this solution. Do not swallow.

  • Rinse your mouth with Milk of Magnesia to coat sores.
  • Orange juice is helpful in preventing the canker sores of the mouth. Drink it up in 2 or 3 days it will go away. Lack of vitamin C causes them. You can also take Vitamin C pills if you don't want to drink all that orange juice.

  • Cover the ulcer with a wet tea bag; the tannin will help dry up the sore.
  • Mix sodium bicarbonate powder with water. It is a very effective first aid remedy. This mixture can be used as a mouth rinse as well as swallowed to help make the body more alkaline.
  • Use a toothpaste containing sodium bicarbonate instead of the standard toothpastes high in fluoride and other chemicals.

  • Antacids can soothe canker sores by reducing the acidity in your mouth that can irritate them.
  • Combine equal parts of the liquid form of Kaopectate or Milk of Magnesia (both antacids) with Benylin or Benadryl (both mild anesthetics). Apply the mixture to the canker sore with a cotton swab. You'll cut down on painful acidity in your mouth and numb the sore, too.

  • Try stress-relieving acupressure exercises. Avoid constant stress. Take time to exercise, sleep, and relax.
  • Avoid eating fish or meat of any kind for two weeks. The consumption of animal protein increases the body's acidity, which slows healing.

  • Avoid chewing gum, lozenges, mouthwashes, tobacco, coffee, citrus fruits, and any other foods that you know trigger these sores.
  • Avoid hard toothbrush bristles or sharp-edged foods such as potato chips or dry bread crusts. Too much acid from fruits and vegetables, and spicy foods can also trigger mouth sores.

  • Keep the bowels regular to prevent toxic buildup. Walk regularly, walking in fresh air to oxygenate the body and stimulate bowel movement.
  • To avoid getting canker sores, it is important to maintain a proper balance of minerals, acidity, and alkalinity in the body.

  • Do not use the same toothbrush for longer than one month.
  • Application of peppermint oil helps, as it is an anesthetic agent.
  • Mix coconut milk with honey and massage the gums 3 times a day.
  • Take 1 tsp finely powdered Indian Gooseberry root bark, mix with honey. Apply to affected areas frequently.

  • Grate some fresh coconut. Extract the milk and gargle with this 3-4 times a day.
  • Keep 1 glass of chilled water and 1 glass of hot water ready at hand. Gargle alternately with hot and cold water.
  • Boil 2 cups of water. Add 1 cup fenugreek leaves and remove. Cover and keep for sometime. Strain the water and gargle 2-3 times a day.

  • Boil 1 tsp of coriander seeds in 1 cup of water. Remove when slightly warm, gargle. Repeat 3-4 times a day.
  • Chew on 5-6 tulsi (holy basil leaves) and sip some water. Repeat 5-6 times a day.
  • Raw tomatoes help get rid of mouth ulcers. Gargle with tomato juice 3-4 times a day.

  • Mix 7 parts of sugar candy (mishri) with 1 part of camphor. Apply on the blister.
  • Mix a pinch of turmeric powder to 1 teaspoon of glycerin and apply.
  • Avoid hot or spicy foods to minimize discomfort. Mild mouth washes such as salt water or over-the-counter mouthwashes may help.

  • Apply hydrogen peroxide (1 part hydrogen peroxide and one part water with a cotton swab) on the canker sore
  • Pouring salt directly on the ulcer can prove effective, however this can be extremely painful and can scar.
  • Rinse mouth and especially the affected area with sage tea 3 times a day. The improvement can be seen within 24 hours.
  • Gargle a mouthful of warm vinegar with half tablespoon of salt for about 30 secs, 3 times a day. Extremely painful, but healing can be seen in about 2 days.
  • Make a paste of baking soda and water and apply directly to the sores.

Homeopathic remedies can ease the pain of canker sores, reduce inflammation, and help the tissues heal.

Arsenicum album: A person who breaks out in burning, painful mouth sores, and also feels anxious and tired, is likely to benefit from this remedy. Hot drinks often ease the pain, and the person feels best when keeping warm. They often have unhealthy, easily-bleeding gums, and tend to be extremely neat and tense. Arsenicum album is recommended when the mouth is dry and burning, and the ulcers are soothed by warm water. Restlessness and anxiety are felt. Often caused by stress and worry.

Borax: This remedy is often helpful when canker sores feel hot and sensitive. Sores may break out on the inside of the cheeks, on the gums, and on the tongue. Produces profuse saliva, yet still feels dry inside the mouth. Other indications are: sensitive to noise, suffers from motion sickness, bleeding ulcers when touched, and hot and tender mouth.

Calcarea carbonica: This remedy is often indicated for infants and small children who suffer from recurrent canker sores. Other indications are: head-sweats during sleep, and slow to teethe or learn to walk. May also aid with canker sores in adults who are chilly, stout, and easily fatigued.

Hepar sulphuris calcareum: This remedy may be indicated when a person develops painful mouth sores that become infected-with pus formation, extreme sensitivity, and aggravation from cold drinks. Often feels extremely chilly, vulnerable, and oversensitive.

Mercurius solubilis: This remedy is useful when bleeding gums, a swollen coated tongue, and offensive breath are seen along with canker sores. The sores feel worse at night, and salivation is profuse, with drooling during sleep. The person tends to sweat at night and is very sensitive to any change in temperature.

Natrum muriaticum: Pearly sores that erupt inside the mouth, especially on the gums or tongue, may respond to this remedy. The mouth feels dry, and the tongue may have a tingling feeling. Often troubled by cold sores around the corners of the mouth or chin, and have chapped or cracking lips. A craving for salt, strong thirst, and a tendency to feel worse from being in the sun are other indications for Natrum muriaticum.

Nux vomica: A person who needs this remedy may break out in canker sores after overindulging in sweets, strong spicy foods, stimulants, or alcoholic beverages. The person may have swollen gums, a coated tongue, and bloody salivation. Irritability, impatience, and a general chilliness are often seen.

Sulphur: For sores that are painful, red and inflamed, with burning pain that is worse from warm drinks and aggravated by heat of any kind. The mouth may have a bitter taste; the gums can be swollen and throbbing. Reddish lips and mucous membranes, and a tendency toward itching and skin irritations are other indications.

Dosage: Follow the label directions. Take one dose and wait for a response. If improvement is seen, continue to wait and let the remedy work. The frequency of dosage varies with the condition and the individual. (03/26/2008)

Last time I got cankers and there were 3, 2 top and 1 bottom, I couldn't eat well. Here in the Philippines somebody told me to use "Tawas" this is a mineral, good thing, it is very cheap, available in the streets. Just break a small piece and put it in your mouth and rub it on the affected area and rinse your mouth, after 2 days it will disappear.

I tried putting salt directly on them and that hurt very bad, so I would say rinse with hot saltwater. My grandma used to tell me to do that, and it usually worked. (01/03/2009)

I drink pure green tea with no sugar (Ito En, to be specific), and it really cuts the pain and seems to speed up the healing process. I also just avoid super-sugary stuff in general to try and keep the mouth as clean as possible so it can heal faster. And finally, mouthrinse (the antiseptic, not mouthwash) is key, since it will kill bacteria and numbs the sore it a bit. (02/24/2009)
