Had a "sub" hygienist who didn't believe me when I told her that there was still some tartar on my front bottom inside teeth and that she missed polishing the entire front portion of my mouth (top and bottom). After I told her and she completely verbally disagreed with me, she reluctantly went back to review this area and removed tartar ( Oh, yes your right there is still some there!) And she polished only the bottom teeth. I could not wait to get out of there so I did not say anything about polishing the top. My normal hygienist has a routine, this hygienist was all over my mouth with no set routine. Absolutely love Hinsdale Dental when my normal hygienist is there.
