Bleeding gum is due to various reasons for example:-
-use of aspirin
and anticoagulants etc. I advice you visit a dentist
once in every 3-4 month for plaque removal. Use soft bristle tooth-brush. Use floss twice a day it prevent plaque formation.
Tooth paste with triclosan should be used.
Use anti-plaque mouthwash two times in a day for 15 days.
A balanced healthy diet
should be taken.
