I had dental work done at the Spring Hill, Tn location. The billing has been a nightmare. I carry insurance that is very clear on my out-of-pocket expenses. I had dental work done in 2019. I had been overbilled for several office copays in the same visit, procedures that I did not have, etc. In 2020, after multiple calls to their offices, and "tickets" being started and months later, I finally was able to reach a district manager who arranged for me to be refunded what I had overpaid due to overbilling. It took a lot of time to get my money back. Fast forward to March 2023. I have received a collections notice on behalf of Aspen Dental. I have not gotten a statement from them since the refunds were made. (2020) They have erroneously billed me $173- no dental codes involved and now the collection agency is sending notices. I have communicated with the collection agency however they do not seem to comprehend all of the factors involved. Outside of billing, I still would never recommend these offices. The staff has zero accountability, zero ability to do anything other than repeat quotes and look at you like a deer in headlights. The dental work was substandard in that they used cheap materials for my fillings. NEVER USE THEM! I will be reporting them to the BBB along with this review.
