I had a root canal done. It was honestly, practically pain free, starting with the initial shots. Dr. Newsom was very gentle and talked throughout the process giving little warnings like, a little shaking on the tooth, etc.
I'd take my kids to him if they ever needed his type of services, and I'd never consider going anyplace else after having been to him.
It's worth noting that his assistants and entire staff are very friendly and professional, also.
