Hello sir. Why blood leaking through mouth while...

Treatment of your condition:
First of all, it's recommended to visit your family doctor for further assessment of your condition. The doctor will make the diagnosis of the condition you are suffering from. After this, the treatment will be planned according to the disease. Anyone who encounters a bad situation such as bleeding from the mouth during sleep should see a doctor without wasting time because the cause can be very serious.
For example, if there is ginivitis, treatment usually includes a professional dental cleaning followed by a good oral hygiene routine. Later stages of the condition may require surgical treatment. If there is mouth ulcer, treatment isn’t typically needed, as they tend to clear on their own. If they grow large or last for more than a couple of weeks, your doctor might recommend prescription mouthwash with dexamethasone or lidocaine.
