Oddly enough, what a tough question! The best we can do is offer our process for choosing a dentist. Baltimore's Best magazine is a great resource to discover the doctors who were able to do all that had to be done to get on the IT list. Of course it doesn't mean there aren't other doctors out here who are worthy.
We would have some additional questions for you: Are you looking for a dentist that looks like you? Are you looking for a dentist that is personable (we've come in contact with a few introverted dentists!)? Are you looking for a family friendly practice, where your children and happily be served as well? Are you looking for a dentist who is not as invasive and will only do work that MUST be done? We have a different dentist to answer each of those preferences. And we have not even touched the issue of insurance providers! So we hate to answer a question with MORE questions, but its pertinent to give an answer.
