This might come as something of a shock, particularly in this day and age of vanity and ridiculous media vanity, but the top cosmetic procedure in America is teeth whitening. Nuts! U.S. citizens plunk down nearly $2 billion annually on home-bought whitening products that you can snag from your local drug store and/or grocery store. While those bleachy products may offer a short-term solution, buyer beware! There can be long-term effects that can make that sparkle in your smile seem like the shine of the damned! You have to watch out for over-using and possibly purchasing the wrong whitening product, so Refined Guy is here to tell you which whitening tricks aren’t total BS!
