Dr. Specter is without a doubt the best dentist that I have ever gone to in my 50+ years or dental care. I have met a few people like Dr. Specter in my life, this is a man who loves what he does. I personally would never want to do dentistry for a living but Dr. Specter is one of those rare individuals who almost seems to have been born to be a dentist. If you want the best possible dental care, anywhere, then Dr. Specter is for you.
On the other hand if you hate spending time a dentist chair then you may not like the way Dr. Specter works. He believes in getting it right the first time, and if that takes a bit longer to do then he will take his time. I have never had any trouble with any of the work that Dr. Specter has done (fillings, crown, root canal, cleanings, etc.) and would trust him with any work that he is willing to perform, but he will tell you immediately if he feels that a proceedure would be best performed by someone else.
Dr. Specter is an artist at what he does. He is extremely careful to minimize the discomfort to his patients, but he is not quick. If you are looking for a dentist that can do a filling in 3 minutes, that will last 3 years go somewhere else, but if you want it done right go to David.
