Q. Im 52, hopefully not too late to take care of my very damaged teeth. ive been told for years to get a deep cleaning and ive been scared, so i havent. i brush daily, not alot of flossing. well, first thing, my bridge fell off (5 years old) two teeth underneith the bridge broke. its on now again, but for how long? second, i was told my bone has really decreased. i noticed my bite changing, but thought it was normal, well my teeth are shifting, one is floating according to my dentist. he recommends deep cleaning. i am rinsing with a presectiption rinse, am on antibiotics cause now i have infection above bridge area, and i floss maybe 6 times a day, brush twice. am i too late? HE SAYS less comprehensive is deep clean, most comprehensive is dentures. i dont want dentures. am i doing the right thing, or is it too late for me now.
