Dr. Ostler in Richland is my dentist, and even other dentists in town will tell you he's one of the best. He doesn't do root canals, so when you need one he refers you to Advanced Endodontic Care in Kennewick. Steven W. Hansen was my DDS for this and it was a great experience! Sounds weird...a great experience with a root canal LOL. So what exactly is it that makes you pain free with a root canal...hey watch this!
