    A rather uncomfortable piece of equipment was shoved into my mouth before I was under. The area…read morejust under my nose is numb. I still have two bits of bone making denture wearing painful. When I left the office after surgery, along with plenty of cotton stuffing, they shoved my temporary dentures into my mouth. Why? My temporary dentures would not stay in after visits to correct the problem. No one was really rude, but I got the impression they were in a hurry. I truly wish I had researched denture providers before choosing Aspen. I didn't get a lot of time to think about what I was getting into at the first visit.

    March 28, 2025, I went to Aspen Dental in Glen Carbon, IL for routine dental work following a…read moreconsultation a few days earlier. I was advised to undergo periodontal treatment and a tooth extraction, which I approved ahead of my Friday appointment. After being taken back, I was given numbing injections to prepare for the periodontal procedure. However, I was then left alone in the chair for over 45 minutes with no one checking on me. Knowing the office closes early on Fridays, I became concerned as time kept passing. Eventually, a technician came in and completed what was supposed to be a full periodontal treatment in about 15 minutes for all four quadrants. I've had this procedure done multiple times before, and it has always taken well over an hour. When she began finishing up, I asked if the treatment was complete, and she said yes. I also asked about polishing, and she told me it wasn't included. At that point, I could hear staff rushing around. When I asked what time they closed, I was told they were closing in 10 minutes--which explained why the procedure felt rushed, especially after I had already been left waiting for so long. I was also supposed to have an extraction done that day. A few days later, I called the office to report that my teeth still felt like there was debris left behind from the "treatment." I was scheduled to come back in, and after new X-rays were taken, it was clear that significant areas had been missed and needed to be redone. I spoke with the office manager and expressed my dissatisfaction with the poor quality of care, especially given the high cost. We agreed that I would be refunded all out-of-pocket expenses, and only the periodontal treatment would be billed to insurance, with all other services (extraction, flipper, etc.) refunded. I saw refunds issued back to my credit card, so I assumed everything--including the insurance refund--had been handled. However, when I went to another dentist recently, I found out Aspen Dental never refunded the insurance company as promised. I called to speak with the office manager, but was told she had just joined a conference call. The person I spoke with immediately became defensive and claimed they could not issue refunds for services already rendered. She also stated she was not present when the original agreement was made. This entire experience has been frustrating and unprofessional--from rushed and incomplete treatment to poor follow-through and lack of accountability. I strongly recommend thinking twice before agreeing to services at this practice.
