Blisters on the tip of the tongue may be physiological, or may be caused by pathological factors such as congestion and edema of the fungal papillae, traumatic tongue ulcers, mucous gland cysts, herpes stomatitis and so on. 1. Physiological factors: If there are many papillae such as fungal papillae on the surface of the tongue, the vesicles on the tip of the tongue may be the normal physiological structure, and if there is no other obvious discomfort, there is no need for treatment. 2. Pathological factors (1) Bacterial papillae congestion and edema: mostly seen in patients with gaping teeth and refillings, which cause the tongue to lick the teeth all the time, causing the bacterial papillae to become congested and edematous. This causes the bacillary papillae to become congested and edematous, which manifests itself as the symptom of long blisters on the tip of the tongue. (2) Traumatic tongue ulcers: If the tongue is burned or scratched by eating too hot or too hard food, it will cause traumatic ulcers on the tip of the tongue, which will be manifested as symptoms of long blisters on the tip of the tongue. (3) Mucous gland cysts: small bubbles appear in the abdomen of the tip of the tongue, there are many mucous glands in the abdomen of the tip of the tongue, if the outlet of the mucous glands appears to be blocked or the catheter is cracked, then it is easy to cause mucus retention and the formation of small bubbles on the tip of the tongue. (4) Herpes stomatitis: related to herpes virus infection, can cause oral mucosa and tongue surface blisters. If the blisters on the tip of the tongue have not disappeared for a long time, it is recommended to go to the hospital in time to find out the cause of the blisters and then actively treat them so as to avoid delaying the condition.
