I had my bottom back molar extracted.Had to wait about an hour in the waiting room. I received a local numbing and let it take effect for bout 6-8 mins. Dr Sibley Then came in and pulled the tooth, it blew my mind, I was expecting 15 mins of work, he said you are going to feel some deep pressure and 2-3 mins later he say " it's out" couldn't believe how fast it all went. i would recommend him for sure. thank you Dr Sibley.
