Dr Marshall is the best of the best. The Yelp description of "general dentistry" is, I believe, incorrect. Dr Marshall is an endodontist. Endodontists have a couple more years of training beyond that of general dentists. They are experts of assessing tooth pain and, where necessary, doing root canals. Some general dentists do root canals. However, I understand it's difficult to remove ALL the pulp from within the roots because they are curved and the shapes vary from one person to another. If the job is not done thoroughly, it may have to be done all over again. My general dentist wanted to do my second root canal but I refused even though he offered to do it at about 60% of the cost I paid Dr Marshall. Far as I'm concerned, the extra cost for an endodontist is well worth it and I question why the dental regulators even allow general dentists to do root canals. I've had two root canals by Dr Marshall, the first one being very elusive as to which tooth was causing the problem. Dr Marshall took gobs of time to make sure to find the correct tooth. Both times there was no pain or other discomfort and the whole procedure was quite entertaining. He is very personable and it's very reassuring to know you have a top expert taking care of this kind of problem. read more
