When experiencing oral ulcers, patients can appropriately drink milk. Oral ulcers are a type of oral inflammation, where localized areas in the mouth develop ulcerative lesions, often accompanied by significant pain, and the ulcerative surfaces may exhibit white substances. At this time, patients must pay attention to oral hygiene and nutrition, rinse their mouths promptly after meals to remove food residues and prevent bacterial infections that could irritate the wound. Additionally, patients can not only drink milk but also eat other nutritious foods such as eggs, lean meats, fresh vegetables, and fruits. These can effectively supplement various nutrients needed by the body, which are beneficial for the healing of oral ulcers. Therefore, when patients suffer from oral ulcers, they must ensure a light and balanced diet.
