My visits are not as good as they used to be. Usually my tooth were throughly cleaned, but last time, only the tips were cleaned. Around the gum line and a few millimeters down, there is still dark, and apparent, discoloration. My teeth look like they are shaded. I also think that due to the lack of cleaning, my gums are receding.
I did not want to write this, but I am concerned that the job was improperly done.
