Over charges on double coverage customers. cleaning 140, charged us 168. split between both insurance companies and out of pocket of 48. that's crap. root canal cost of 2600 after insurance. very greedy, recommends not using dental insurance over their own plans which costs more and coverages less. my teeth don't line up, my jaw constantly hurts, can't afford to finish the root canal procedure even. others quoted me 1000 with my insurance. Smiles refuses to contact me regarding their over charges. I do not recommend using them. they also recommend less important procedures so they get you with no insurance coverage for expensive coverage.
