Generally speaking, limes are not typically effective in treating oral ulcers and may instead worsen the discomfort. Detailed analysis is as follows:
Oral ulcers commonly present as damaged areas or sores on the oral mucosa. Limes contain significant amounts of citric acid and other acidic substances. When these substances come into contact with the ulcerated area, they can irritate the damaged mucosal tissue, causing intense pain. They may also disrupt the microenvironment of the ulcer, interfere with the mucosa's natural healing process, and delay recovery. Additionally, the irritant nature of lime can cause redness and swelling in the surrounding tissues, thereby exacerbating the symptoms.
When oral ulcers occur, acidic and irritating foods like limes should be avoided. Instead, one can choose mild, easy-to-chew foods and maintain good oral hygiene. If necessary, specialized oral ulcer medications can be used to promote healing. If oral ulcers recur frequently or persist for a long time without healing, timely medical consultation is necessary to rule out other potential diseases.
