Bleeding every day when you brush your teeth is not necessarily AIDS. The most common clinical cause is bad periodontal disease, gingivitis, and periodontitis will lead to red and swollen gums and bleeding gums. There are also other hematologic disorders that are possible, such as various types of anemia, iron deficiency anemia, aplastic anemia, and so on. It is also possible to take anticoagulant drugs such as aspirin. Of course, AIDS may also cause bleeding from brushing teeth, so it is best to have an HIV test.
