If you have painful, white lesions inside your mouth, then most probably you have what is called mouth
Stress, smoking, hormonal changes, and deficiency in vitamins such as ascorbic acid (Vitamin C) and cobalamin (Vitamin B12) are common grounds for getting canker sores. Sometimes, this can also be attributed to viral and bacterial infections and certain medicines that you have or take.
However, being one of the easiest to treat diseases, mouth sores can be treated using home remedy options or through oral medication. Gargle with tomato juice at least three times a day to eliminate your mouth
Another herb that is known to cure mouth sores is basil leaves. Chew about 5 leaves at least three times a day. Do this together with water and in a short span of time, your canker sores are gone. Another thing about basil leaves is while it is treating your canker sore, you also get fresher breath. Alternatively, gargling with warm water with salt also relieves you of the pain mouth sores bring. Somehow, the salt solution numbs the sores and will make it easier for you to eat and talk.
Sodium bicarbonate is another option. Combine a small amount with water and gargle with it at least three times a day. If you have peppermint oil at home, apply a small amount directly on the white patches and your mouth
