Earlier I was bleeding gum and I have visited dentist after scaling most of bleeding gone but I feel above symptoms some time. And my right side tooth ache if I eat cold substance Though currently I am not allowed to eat cold substance due to infection in throat. And for which I am taking medicine and gargles. NowI am brush my teeth two times after bed at morning and before going for bed at night. Despite precaution why my above mentioned symptoms occurs. I am using sensodine. Please suggest better measure so that I can take care of my tooth. Thanks.
