as such, but it is tooth #18, it has a crown on it, and I had a root canal on it as well 6 months ago. The
gum around the tooth is slightly inflamed, and has been since the root canal was performed. Yesterday during a routine cleaning, the hygienist injected some sort of medication to destroy some of the bacteria causing the inflamation. Then she gave me a "pikster" brush to insert under the gumline and into the bifurcation to keep it cleaned out.
