Serving Westchester since 1985

Routinely voted amongst the top dental offices in both Westchester and Putnam counties, Rifkin Dental has cared for the Hudson Valley since 1985. With offices in Yorktown Heights & Carmel, NY and over 60 years of private practice experience -- our dentists have seen it all!

That experience extends to the rest of our staff, with multiple assistants and hygienists having treated patients at Rifkin Dental for over 25 years. Our team prides itself on the quality the care they provide, as well as the comfort of their patients before, during and after their time in the chair.

Afraid of the dentist? We won't take it personally. Plenty of patients are nervous the first time they come to visit us, but very few are still holding onto their fear when the appointment is over. And if you're one of those few -- we offer certified sedation dentistry so your procedure will feel like a (pleasant) dream.

But don't just take our word for it, read a few of our thousands of independent reviews.
