The identification and replacement of a former dentist's enamel-shaded cavity filling was quick, efficient and most of all PAINLESS! In and out of the office in approximately 30 minutes, which is SIGNIFICANT in almost any medical treatment. Replacement preparation was pain-free, w/o injection, and the missing filling in and sealed in a matter of minutes. As usual, ALL persons were attentive, courteous and professional! (What else could you ask???).
