What does it means when you wake up with blood on your pillow from your mouth. i dont have any tooth pain. this is the second time this happened. it also happened one time last month?

Blood may be coming from many sources, including your nose, mouth, lungs, or stomach. I suggest you see your dentist for a periodontal examination. Inflamed gingiva (gingivitis or periodontitis) often do not cause pain.

If the blood is from your mouth, than it is from poor oral hygiene. The blood is no doubt from your red, puffy and swollen gums. You have a periodontal[gum] infection and need to see a dentist and or a periodontist for treatment. You can not treat this condition yourself.

Most often means bacterial infection ofnyour gums (gingivitis or periodontitis). But can also indicate disease, infection, lesions of oral cavity, sinuses, throat, lungs, GI tract. Gum disease is treatable. See your Dentist or preferably a gum specialist, a Periodontist. If your gums are healthy you will be referred to appropriate specialist for more studies.
