Hi Syd,
I sent you another PM

With regard to the bifurcation.......
A bifurcation is simply the area of a tooth where the two/three roots come together just below the gumline. It is a "Y" shape with the bifurcation being in the middle of that "Y".

If your nerves were exposed, you would not be able to stand the pain because it would never stop. What probably has happened is.......... the gum receeded past the bifurcation area of the tooth leaving this once covered part of the tooth exposed to the air and other elements. This will cause the tooth to be extremely sensitive to temperature, sweets, brushing, etc. It is also not covered by enamel, so it is more prone to decay, plaque and infection.

As I mentioned in a previous post, it is never good to keep an infected tooth. I understand your other concerns........ all very valid and should be taken into consideration. Perhaps as soon as the TMJ calms down, you may consider taking care of this tooth before it progresses to another area.

Syd, is this a top or bottom tooth?
