Mouth ulcers are usually caused by localized ulcerative damage to the oral mucosa due to viral infections, autoimmune deficiencies, and vitamin B₂ and vitamin C deficiencies. Some of the missing nutrients can be replenished by consuming fruits rich in vitamins such as: kiwifruit, grapefruit, oranges, apples, peaches and persimmons.
Kiwifruit contains a variety of vitamins, such as vitamin C, vitamin E, vitamin A, etc. On average, there is about 62mg of vitamin C per 100g of kiwifruit, which can replenish the vitamins in the organism when consumed in moderation, and to a certain extent, can alleviate the uncomfortable symptoms.
In addition, when symptoms occur should avoid spicy, irritating foods, such as onions, ginger, garlic, chili peppers, etc. Should also avoid eating too sweet food, such as chewing gum, chocolate, coffee, etc. and too hot food, may be irritated to the affected area, aggravating the condition.
When suffering from mouth ulcer symptoms, you can use compound benzocaine gel, compound chlorhexidine gargle and other medications for treatment under the advice of a professional doctor, and take oral vitamin B complex tablets and so on if necessary.
