Don't understand superjon's review...yes, the option to put your small child under is there, but you don't have to! It's definitely not required unless they see that during cleaning and X-rays that your kid is squirmy and won't stay still. Which begs the question, would you rather the drill just go through their cheek? Anyway, yes, they fill minor cavities... What do you think happens to small cavities? They don't go away, they get bigger and end up costing more! Overall, we had an easy time at this dentist. We did not put our three year old under general anesthesia. All of the staff is super sweet. They really know how to interact with kids and get the job done.
