Nightmare Experience
Went into Dr. Grossman's office for a simple crown replacement, and ended up losing my molar as a result of their bad service. Grossman is easily in his mid to late 70s, and has a female dentist (Dr. Winters I believe) who partners with him.
Anyway, they (Dr. Winter did much of the work) replaced my previous metal/porcelain crown that had broken with a new restoration that broke twice. Eventually they recommended a gold crown, and stuck one in that didnt fit on my tooth or in my mouth. The oversized and ill-fitting crown cracked my molar within 2 days of being placed (down to the root) and the crown on the tooth in front of it. The pain of the tooth breaking was unbelievable.
As a result, I had to had my molar removed and am now going to have to do a $3500 implant to replace the lost tooth.
I have never experienced gross incompetence with a dentist, and assume its pretty rare. BEWARE - IF YOU VALUE YOUR TEETH AND WANT TO AVOID SEVERE PAIN.
