Bleeding gums?: This usually means bleeding gums, so your first move should be to see a dentist. If gum inflammation doesn't explain it, your nose and sinuses are the next most likely possibility. I'm guessing the dentist will find the explanation, but if not, see a doctor. In the meantime, don't be overly worried. Most likely it is nothing dangerous. Good lucik!

See a dentist: It's most likely a more advanced stage of periodontal (gum) disease but there are other causes as well, both dental and medical. When was your last dental check up? See a dentist for a complete and thorough oral, dental and periodontal evaluation.

Blood on pillow: Most common cause is periodontal (gum) disease. How long has it been since your last check up/cleaning? Do you floss daily? First step is to see your Dentist. If your gums and all other oral tissues are healthy, your Dentist will refer you o to your Physician to evaluate sinuses, throat, etc.

Periodontal Disease: The most likely cause is periodontal disease, which is the most common reason for tooth loss in adults. Please see a dentist ASAP as this actually can be serious if not properly treated.
