Tooth ache

For years I have been nursing the promise of a healed tooth. A dentist botched a filling, allowing a chip of the newly hardened material covering a back molar to catch every food particle pressing into the space between my two back teeth until floss broke the nuisance off. However, by this time, a cavity had developed between the crevice, and spread to the bone under my gum. I thought that the little bit of sharp protrusion of filling that finally disappeared would let me floss properly. How was I to know that all those days of insufficient flossing had corroded my tooth. I am devoted to my dental hygiene, and loosing a molar is disturbing. I will get the crumbling tooth pulled, but not without mourning its loss.
