Is it best to brush teeth before using mouthwash?

Mouthwash is not a substitute for tooth brushing. Everyone should brush his or her teeth at least twice daily, and floss once daily. This is the minimum frequency necessary to prevent plaque build-up, and the cavities that can result. Mouthwash is used, not to prevent cavities, but to prevent bad breath. Since you're going to brush and floss, and you want to use mouthwash, it makes more sense to use the mouthwash after brushing and flossing, rather than before, since brushing and flossing stirs up bacteria and other malodorous debris.
