Publish Date: 2026/1/14


       Has an ulcer in your mouth hurt so much that you even grit your teeth when drinking water? Hurry up and eat more fruits to replenish it, it will heal quickly! "I believe many people have heard this advice. After all, in people's inherent understanding, fruits are rich in vitamins and can definitely help with mucosal recovery. But is this statement really correct?
       It should be noted that the causes of oral ulcers are complex and not necessarily due to a lack of vitamins. Excessive stress, weakened immunity, and local trauma (such as accidentally biting) can all lead to ulcers, and blind supplementation may not necessarily be targeted.



       More importantly, many fruits have a stimulating effect on oral ulcers. Keep in mind that its wounds are already sensitive and fragile, and acidic fruits such as lemon, grapefruit, pineapple, etc. can directly stimulate the ulcer surface, aggravate redness, pain, and even prolong healing time.



       In addition to acidic fruits, there are two types of fruits that are also recommended to temporarily avoid: first, hard fruits such as apples, pears, and sugarcane, which can easily rub against the ulcer surface when bitten, exacerbating the pain; The second is overly sweet fruits, such as lychee, mango, and durian. High sugar content can promote the growth of oral bacteria, exacerbate inflammatory reactions, and also delay healing.



       Of course, we are not going to give up eating because of choking. The nutritional components in fruits are indeed beneficial for overall health and mucosal repair, with the key being "selective" and "skillful" intake.



       Prefer fruits that are gentle, non irritating, and have a soft texture, such as bananas. They do not require chewing and melt in your mouth. They are rich in potassium and can replenish energy without stimulating ulcers; If you want to eat apples or pears, you can also cut them into extremely thin slices or squeeze them into residue free juice to avoid biting them directly.



       Additionally, it is important to remind everyone to consume fruits at room temperature during oral ulcers. Fruits that have just been taken out of the refrigerator and are too cold can stimulate the oral nerves and worsen pain; Eat slowly and let the fruit stay in your mouth for a shorter period of time to reduce irritation to ulcers.



       Laiwo Medical Warm Reminder: "Eating more fruits for oral ulcers" is a suggestion that needs to be refined. It is not a universal key, and this suggestion is far from enough to solve the problem. Regular sleep, eating less spicy and stimulating food, and doing a good job of oral hygiene are more reliable methods. If the ulcer persists for more than a week and even worsens, don't take it too hard. It's wise to see a doctor in a timely manner!
