I have had quite a bit of work done to mouth. From oral surgery to a routine cleaning, and much in between. I have to say that the level of comfort I experince when talking with, more like mumbling because he is working on my mouth, Dr. Roberts is the most I have felt in any doctor's office. Bayond that, I have never had any trouble with any of the work done to my mouth by Dr. Roberts and he is obviously confident and good at what he does. Another great thing is that he is the only doctor I have been to that can make shots to the mouth completely painless! If I had anything bad to say I would say it, but this really is purely a great review.
