I am 25 yrs old, i tend to leave saliva marks in the pillow while sleeping but today along with saliva a significant amount of blood was also seen. I am having my periods as well. i got  my blood test done and it came out to be normal. Can you pls suggest what can be the possible reason?
Thanks for using Chat Doctor. Read your query. The bleeding suggests that there is presence of gingival and or periodontal inflammation (gingivitis)with calculus. I would advise you to visit your local dentist and get a professional cleaning done. Then follow up by maintaining good oral hygiene with proper brushing, flossing and use of mouth wash for a few days. If the bleeding is increased or is more prominent even after cleaning, then I would suggest you to visit your ENT surgeon for further investigation. Hope this was useful. Thanks and regards.
