We all know that the mouth on fire bubbles is mouth ulcer, but everyone knows what causes mouth ulcer? I think there should be a lot of friends do not understand it, I will give you a brief introduction to oral ulcer in the end is what it is. First of all, we need to know how oral ulcers are caused, the appearance of oral ulcers is related to zinc deficiency and vitamin deficiency, especially the frequency of children is usually more frequent. If we do not correctly understand the main reason for her, there will be such a situation: that is, repeated oral ulcers, which is how torturing the situation. On weekdays, we deal with the problem of oral ulcers the most common is to drink water, adults want to tell us to drink more boiled water will be their own good, in fact, we all know, drink more water is useful, but the effect is really painful and long, oral ulcers encountered water when the pain can be imagined. In one, if it is improved by drinking water alone, the probability of repeated attacks is very high, which can only be said to treat the symptoms rather than the root cause. In one is that when we go to medicine to consult what medicine to eat for oral ulcers, the staff will recommend you to buy watermelon cream. This is a kind of medicine that contains a lot of vitamins for the treatment of oral ulcers, friends who have used it should know that it is also more inconvenient, mainly to apply watermelon cream to oral ulcers, so that it can slowly absorb, can not drink water, saliva has been flowing, and the pain is no less than drinking water. Vitamin c I estimate that many people understand, this is a more complicated method, you need to go to the medicine to buy back ground into powder, and then apply to your ulcer, in fact, the method is similar to watermelon cream, but this application will have a sharp pain feeling, the effect is also general. This method is generally not recommended for children and girls. According to my personal experience, I still feel that zinc supplements and vitamins are the fastest and best, because after all, oral ulcers themselves are caused by zinc deficiency and vitamin B2 deficiency, and only through zinc supplements and vitamin supplements can they be achieved. It is also less troublesome than the previous ones, and there are rarely repeated episodes. In daily life, the diet must be self-disciplined, should not eat too spicy and hot food and snacks, these are one of the main causes of oral ulcers.
