Hello dear,
First of all dont worry and be relaxed. I have gone through your query thoroughly. I will provide you with my best possible advice.
First of all I would like to tell you that always discuss problems with your doctor because it will help him/her to make more accurate treatment plan.
Blood in the spit may arise due to many causes. But the most common cause is gingivitis(
gum inflammation) or periodontitis(pyorrhea).
Usually it gets corrected after scaling.
Meanwhile I am advising few things-
* Use ultrasoft toothbrush and brush your teeth twice daily.
* Use gum astringents like stolin/dentakind-L 3-4 times a day for 15 days.
* Eat more green leafy vegetables and have diet rich in protein.
* Warm saline gargle 2-3 times daily.
Hope this will help you. If there is any more query or question regarding this in your mind, you are free to ask any time.
Take Care
Regards
