A change to your teeth cleaning routine
A change in your brushing or flossing routine can increase the risk of bleeding gums. If you increase the rate per week at which you brush and floss or take a couple of days off from your regular dental hygiene routine, then you could get some bleeding and poses a risk for gingivitis. However, it should only happen a couple of times. If it occurs every time you floss or frequently, visit your dentist for a detailed examination.
