Pricey, with mixed results afterward.
in Levittown, NY |
The doctor is just looking for easy cases from people he can rip off. Don't believe the hype. He talks in circles and doesn't deliver on his promises. His staff does a poor job submitting claims to insurance and he's only looking for easy work - misinformed patients that he can price-gouge. I wasn't a candidate because I asked questions. He promised me the moon and sent me packing with less knowledge than I had at the start. Waste of 98 bucks.
I'm sorry you were unhappy after your initial visit. As a Specialist & Teacher I've had the pleasure of helping 100s of patients treated by other dentists & still unhappy. For some, after my exam I do not feel my treatment will improve comfort. It is frustrating to be unhappy after treatment but worse when redone & the patient is still unhappy. The best interests of patients is always my first priority & I only begin treatment when I'm fully confident it will succeed. I wish you only the best.
