13 Home Remedies for Mouth Ulcer That Work

Are you suffering from mouth ulcer? It is a small but painful lesion in the mouth, inner cheek, tongue or gums [1, 2].

Also called canker sore or aphthous ulcer, mouth ulcer is often confused with cold sores, but this one is not contagious, and usually does not require medical treatment. In fact, it can heal on its own within one to two weeks [1].

It also looks quite different. Cold sores are pus-filled blisters while mouth ulcers are open lesions that are enclosed within a white or yellowish ring [3].

The exact cause of mouth ulcer is not known, but in most cases, it is a result of damage or trauma to the lining inside the mouth from poorly fitting dentures, over-brushing, accidental biting of inner cheek or tongue, and so on [2, 3].

Mouth ulcer usually goes away on its own after a few days or weeks, but since it can make eating and talking difficult, you might want to get immediate relief using some natural remedies.

Natural Remedies for Mouth Ulcer

1. Aloe Vera

Abundant in vitamins, minerals, enzymes, amino acids, and saponins, aloe vera has many curative purposes that have been recognized since the ancient times [4].

In dentistry, it is used to treat various types of acute mouth lesions such has herpes sores, mouth corner crackers and mouth ulcers [5].

It does so without leaving a bad taste in your mouth or causing stinging sensation [5].

It has a soothing effect on the gum tissues that that may have been scratched or injured by sharp foods, toothpick, hard foods, or chemicals [5].

According to Chinese researchers, the polysaccharides in aloe vera stimulate the enzyme activities and boost the immunity [5].

In particular, a polysaccharide called glucomannan promotes the activity and spread of growth factor receptors, which in turn, facilitates the production of collagen [5, 6].

In a 2012 study conducted by Iranian scientists, 40 patients with mild mouth ulcer were given either aloe vera gel or placebo [7].

It was found that those who received aloe vera gel had a more significant reduction in the size of wound and pain compared to the other group [7].

What You’ll Need:

  • 1 aloe vera leaf

Recommended Directions:

  1. Break the leaf.

2. Vitamin B12

Nutritional deficiency is bad for the health. As you know, many of the bodily processes heavily rely on our daily intake of nutrients.

Lack of certain vitamins or minerals can also pave the way for the onset of ailments.

Deficiency in vitamin B12 for example is one of the factors that have been linked to mouth ulcers [8].

According to a clinical review performed by American researchers, lower dietary intake of this B vitamin resulted in recurrent cases of canker sore [9].

This review involved 100 subjects who have experienced at least three episodes of mouth ulcer in the last 12 months [9].

Therefore, they recommend sufficient intake of vitamin B12 as a “useful strategy” to reduce frequency and duration of this illness [9].

Similar results were derived from a 2009 study, in which 31 people with recurrent canker sores were given vitamin B12 tablets while 27 people were asked to take a placebo [10].

Those who took vitamin B12 tablets reported of dramatic reduction in the number of ulcers, episode duration and levels of pain [10].

It was concluded that vitamin B12 is a “simple, inexpensive and low-risk” yet effective treatment for those complaining of recurrent aphthous stomatitis [10].

What You’ll Need:

  • Foods rich in vitamin B12

Recommended Directions:

  1. Include in your diet foods that are rich in vitamin B12 such as meat, eggs, poultry and dairy products.
