I had a most bizarre periodontal exam. I am getting a new dentist after moving. I went to an establishment that looked well appointed and had a decent reputation. The dental exam on the gum, however, was rather weird. I never had an exam that hurt before. The dentists I have had in the past touched the gum to taking a reading but never jabbed into it as far as I could feel. The new dentist not only jabbed but also twisted once deep in. Is that normal? More importantly, would a bleeding gum show differently in an X-ray? He showed me the X-ray which seemed indicated a rapid deterioration. Since the last X-ray 8 months ago, I didn’t notice any symptom outwardly, bleeding, swelling, etc. often associated with infection. Can an infection set in so fast without ever bleeding? I had a teeth cleaning in May. It didn’t bleed during the cleaning. Wouldn’t that mean there was likely no infection? In mere four months, the bone deteriorated too deep to support the tooth?
