Do not go here! Champaign Dental Group is a commercial business intended to exploit students. It is NOT a regular dental practice. They're more interested in pushing services and making money than most regular dental offices. The people are nice, the hygienists are good, but the business is structured in such a way that they all have incentives to sell you on as many services and products as possible. That is fine for an electronics store in the mall - it is NOT fine for a medical office, where all procedures have risks and leave permanent changes to your body.
I haven't had a cavity in years. Dr. Collins insisted that all my fillings had to be replaced. He also told me I had several cavities that needed to be filled. I asked whether it was urgent or whether I could wait a few months until my insurance kicked in. He told me if I waited a few months, I would probably need root canal. I didn't have any tooth pain and this all seemed shady, so I declined. Six months later, I went to an experienced dentist for a cleaning and a second opinion. No cavities, nothing wrong with my fillings.
Everyone at Champaign Dental is very nice. But do not go here if you want an honest assessment of your teeth.
