"Too good to be true, I had a tooth extraction last month, and I didn't feel any pain at all. Not the shot and not the procedure after that. The procedure a bit tricky as the tooth was consumed by decay and became fragile. I also had teeth cleaning there and it was best I had in terms of pain and speed."
