Didn't clean enough, even I only have 4 teeth I noticed need to be carefully clean. After cleaning, I still need to clean by myself with the front 2 teeth. Usually the cleaning lasting about 20 minutes, this time, the cleaning only lasting about 5 minutes. Won't visit next time

I made an appointment and had to wait one hour and a half and couldn't even get everything done! Wouldn't recommend it! I want a refund!
