These guys, basically milked my insurance. I had a referral from my primary dentist office, to see an endodontist. Ok... I chose Advance Dental because they were an "in network" office. However, Advance Dental, said they don't take outside referrals and I therefore had to do a visit with there dentist before I could be seen by their endodontist for a consult... Ok... During the initial dentist visit with them, although I had recent x-rays from my primary dentist, they took their own and ended up telling me what I had already knew, and been told by my primary dentist. Ofc this visit and the x-rays went towards my annual alloted dental funds. Nevertheless, I waited a week for my "consult" with the endodontist, where an MRI was taken, only to be told that, I had an out of pocket expensive of $1,000 For a reroot canal, and would have to set another appointment if I agreed... They said my insurance pays $1,4000, but they charge $2,400. I explained that as an "in-network" provider, they'd be contractually obligated to perform the procedure within the price range negotiated between them and the insurance company... They didn't have an answer and went to some back room to talk, only to return and state that it'll take 3 weeks for a pre-authorization, and even then I'd have to come out of pocket $1,000. I explained that I'd be writing this review and filing a grievance via my insurance company. The place just seems like a big money grab from the hard working people like myself who's union pays for good dental insurance. Hell, I didn't even pay anywhere near $1,000, out of pocket for my implant, done by Park Dental of Brooklyn on Knickerbocker! I wouldn't suggest Advance Dental to anyone!
