Bleeding gums
It is possible to have bleeding gums if you just follow a wrong flossing or brushing technique or if you’re too aggressive with your teeth. It might also be common if you use blood thinners for a medical condition. But bleeding gums at the least effort and spontaneous gum bleeding should warn you, especially if you have sensitive gums with a change in coloration. If you’re pregnant, there’s a condition called pregnancy gingivitis that should also be addressed by your doctor.
