<human>: 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?
<bot>: 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.
