I've had three of mine out in the chair (the fourth hasn't erupted yet) I had the two on my left first and the lower right about a year later. Mine were also starting to decay. Because it wasn't too far gone, it came out without breaking. I know if it is too decayed it can make extraction difficult.

My dentist is awesome and got all teeth out in under 2 mins per tooth! I found I needed a panadiene/neurofen combo for pain for a few days and was then fine. I know I'm pleased they are out!
