Floss before going to bed

yep your mate will never have to floss with g -strings on :p even has a cherry flavour coating
 
Flossing and then brushing helps remove plaque, a sticky substance that accumulates and hardens over time. Left untreated, plaque deposits can eventually lead to disease and decay. Learning the proper way to floss is important. Great Bear will be happy to demonstrate proper flossing techniques.
