After bad root canals in the army, a tooth had to be removed. It was an upper, so I did have some minor complications with my sinus cavity being so close. A Dr. had put out a coupon and despite everyone trying to talk me out of using a coupon, I read reviews on him (all good) and used it.
I couldn't have asked for a better doctor or better choice. I can handle mouth pain well, so I can say it didn't hurt, although the knocking to break through the sinus cavity was bothersome. Here I am, 2 years later and have loved my dental implant!
