Should I brush or floss first?
Either way is acceptable as long as you do a thorough job. However, if you use dental floss before you brush, the fluoride from the toothpaste has a better chance of reaching between teeth. Some people brush their teeth and unfortunately skip flossing because they think their mouth feels clean, or they may be short on time or tired and flossing is postponed. That is not a good idea - always remember to floss!
