I was very, very pleased that my dentist did my teeth cleaning this time. They were not cleaned properly on my last visit and I could see buildup and black streaks on and in between my front teeth (upper and lower) after the appointment. I regret now not coming back in for a correction. I really feel and could see a huge difference this time when the cleaning was performed properly. One addition I would make is to perform an oral exam for mouth cancer. I heard a PSA on the radio and it reminded me my other dentists have done this. Thank you for your considerations and thank you again for a WONDERFUL teeth cleaning. I am very pleased. kateshedron
