I was supposed to extract 4 teeth, but I didn't want to lose 4. Dr. Shefferman came up with other option with 2 teeth extraction, explained clearly how the final appearence would be different compared to 4 teeth extraction. I completed the treatment, and I'm very satisfied with the appearance, and keep more teeth! Since I'm a foreigner, I was scared to hear a lot of technical words, but Dr. Shefferman and his staff always explained to me in a easier words and asked my any request (pain relief, how comfortable with insisalign, how urgent to complete...). it was great investment for this quality & professional services. All staff are friendly, relxed, but respectful. I really recommend Dr. Shefferman! Thanks the Dr. Shefferman's team for providing services that met my needs in a limited time!
