1. Mental factors

Some patients become ill when they are under mental stress, mood swings, or have poor sleep, which may be related to autonomic dysfunction.

2. Genetic factors

If both parents suffer from recurrent oral ulcers, about 80-90% of their children will suffer from the disease. If one parent has the disease, about 50-60% of their children will suffer from the disease.

3. Other factors

Lack of trace elements such as zinc and iron, lack of folic acid, vitamin B12 and malnutrition can reduce immune function and increase the possibility of recurrent oral ulcers. Viruses may be the initiating factors of oral ulcers, but relevant antibodies have not yet been found in patient serum, and there are no reports of isolating viruses from oral ulcer lesion tissues. The role of bacteria in oral ulcers has been proposed for many years. The bacteria closely related to oral ulcers include Streptococcus sanguinis and Helicobacter pylori. The imbalance in the generation and clearance of superoxide free radicals in the body, the imbalance in the ratio of thromboxane B2 and 6-keto-prostaglandins, and the decrease in overall levels can cause oral ulcers. Microcirculation disorders lead to slow blood flow, low blood volume, and dilation of the diameter of the capillary venous end, causing local ischemia and hypoxia, thereby causing mucosal damage and ulcer formation. Serum zinc deficiency, iron deficiency, and high copper content are correlated with the occurrence of RAU. There are reports that quitting smoking can also induce oral ulcers. The ingredient 1,2-dimethoxysodium sulfate (SLS) in toothpaste may irritate the mucous membrane and induce oral ulcers.
