I start out with floss. (When flossing, remember that it is important to pull the floss left and right, scraping each side of the spaces between your teeth.) After flossing, I rinse my mouth with peroxide. I let the peroxide rest on my tongue, then swish it up from the bottom of the mouth, in to the gums, with a rowing motion. Peroxide erodes enamel, but not significantly, unless you hold it in your mouth for more than 8 seconds. Keep it under 8 secs; you'll be fine--eliciting all of the benefits and none of the drawbacks. Also, enamel can regenerate. After the peroxide rinse I do a second rinse, this time with warm water. Warm water will dissolve any sugars in your teeth. Finally, I perform a standard brushing with Crest Extra Whitening toothpaste, using an electric brush, for approximately 7 minutes. Then a final rinse with Crest mouthwash. It is important to hold the mouthwash in your mouth for as long as possible, as you swish it around, feeling the mouthwash burning. This might seem redundant after rinsing with peroxide, but it serves the dual purpose of refreshing your breath--as well as killing germs.
