Aspen Dental

First the told me only one dentist could work on it, then all of a sudden the other dentist did all the work on it after the first visit on months later the tooth came out, then they told me, we must of put the implant in to soon so then I'm out of luck no front tooth, also they put a gold crown on my Lower molar and I couldn't bite down the way I should after they placed it they kept grinding on top of it and put a hole in it, I told them they did it he said well there is cement under it so it's ok, but that's not what I bought!
