Do you brush first or floss first?
Brush, then floss.
Floss, then brush.
Some more complicated way of combining the two, like brushing half my teeth, then flossing, then brushing the rest.
Only brushing, no flossing.
Only flossing, no brushing.
Some other method of tooth-cleaning entirely (WaterPiks? mouthwash? chewed sticks?).
Note: If you brush, floss, and use some other method of tooth-cleaning, just answer for the brushing-and-flossing part. If you do different things at different times, answer for whichever you feel is most representative and/or most thorough. (For instance, I brush twice a day, but only floss once. I'll answer for the time of day when I do both.)
