I went to Aspen because I had a bad toothache. I walked out with a $10,000 "plan" for my teeth, even after my generous dental insurance.
I ended up going there for the root canal which, other than the fact it was very expensive, seemed okay. Then they told me the plan for Step 2 - posts and a crown at about $800 after insurance. I went to a different dentist who charged 1/2 that price and did it all in 1 visit instead of 2 that Aspen required.
And they told me I don't need the very expensive "deep cleaning" that Aspen seems to recommend to everyone. And they constantly push for you to get the dental financing.
