I had a graf done by Bruno who "lectures around the world" on the procedure. It was one of the worst experiences in my life. In addition to the very rough technique he used it took me a good 6 months until I did not have daily pain. I was told to expect 1 day of downtime and take it easy for another 5. I had the same procedure done this Friday by another dentist and no major pain and I felt fine the next day.
