Yay!!!! I had a good check up this week too (my 15 year old fillings are in decent shape and can stay, despite some sensitivity in one). I'm petrified of anything involving a drill, so I'm very happy!!!
I'm a grinder too - and my dentist made me a night guard that has helped immensely. I've also been using Act fluoride rinse, which seems to help my teeth stay happy.
