Missing Calculus

Today I missed four spots of calculus because my instruments were dull (at least my graceys were). I think I need to sharpen them after every perio patient because today I saw my class 3 patient in both the morning and night and I should've sharpened my instruments in between when he came in I think because I missed spots because they were dull. I think I need to remind myself to sharpen my instruments everyday before my patients get here so I won't have this problem again.
