When I went in for my last cleaning I found out that my dentist had left the practice, and so when I needed a filling they just gave me whoever was available - it was Dr. Lamond. It was a simple 1 surface filling. Previous to the filling I didn't know I had a cavity and had no discomfort (which I realize is not unusual), but after the filling the tooth was very cold and hot sensitive. Now 6 months later it is still temperature sensitive. My dad is a dentist, and I went home last week and had him look at it. He x-rayed it and said the nerves looked fine(in other words didn't need a root canal). He didn't like the look of the filling though- said it looked like he over-carved it and this could be why I am having the temperature sensitivity. By over-carved he meant when they grind it back after filling - so it's correct when you bite. I was scheduled for an exam only, but Dr. Lamond asked if I wanted to do the filling right then and I said yes. So maybe he rushed and normally does better work? Still not acceptable to me - and my dad also recommended I find a different dentist.
