Although Dr. Sidi has a general practice, cosmetic dentistry is his specialty. He has been my dentist for 14 years, and I still trek over to SF from Berkeley because I refuse to give him up. He is an absolute perfectionist, and as a result he does flawless work. (I think he really sees himself as an artist as much as he does a dentist; he is an amateur Impressionist painter on the side.) Claude has done bonding on my teeth due to wearing and chipping (unfortunately, I was blessed with very soft enamel) and has redone my numerous crowns, replacing them with porcelain ones to match my other teeth. Claude has formed a great relationship with the lab people in his building, and he frequently calls them in to help him with the matching process. I have also seen the results of the more extensive cosmetic work you are talking about; he is really tops in his field. My sense is that his prices are within the reasonable range.
