The ONLY treatment option was extraction with either a bridge, implants, or a removable partial.
The bone loss in the tooth
was too severe to hold the tooth
in and the infection had spread to the other teeth. This happened in a very short period of time, too, and I have always taken good care of my teeth.
If the infection is found early enough, antibiotics and a deep root scaling and planing can help, but only if done soon enough.
Hope this helps.
