Long-lasting mouth ulcers treatment

Question
Hello doctor, I have had mouth sores continuously for several years now, almost every month I have a sore throat, the mouth ulcers are very severe and take a long time to heal. Although I also used folk methods, as well as drinking liver-cooling drinks, but it didn't help. Can the doctor advise on a long-lasting mouth ulcer treatment? Ask your doctor for advice.

Hello! Thank you for trusting and sharing your concerns about Long-lasting Mouth Ulcer Treatment with Vinmec Health System.
Currently, the cause of canker sores is still unknown. Several factors are thought to be related to canker sores including:
Weakened immune system. Viral and bacterial infections. Food allergy Drug allergy. Endocrine changes. Mouth injury. Poor nutrition. Usually, mild ulcers only need oral hygiene, medication, vitamin B supplements, and high doses of vitamin C. In addition, eat cool food (tapioca starch, black beans, centella asiatica...) and improve the health of the whole body. In your case, the symptoms are severe and prolonged, you need to go to the hospital for blood tests and appropriate tests. Best regards!
