The dentist went well, fortunately, and the technician even commented on how my teeth had little staining. She asked me if I had drank less coffee. The reality is I drank just as much coffee (a lot) and tea ( a lot) and smoked a lot of pipes. But I think I may have been better at overall brushing. I probably brush 6 times a day now up from four times a day before. I do not know if the hygienist knew I smoked a pipe because out of politeness I never smoke my pipe on the morning of my visits. She would have given me hell, probably if she knew.
