blinding

back in december, i forgot to update my audience on how the crest whitestrips worked. they worked fine. tasted gross, smelled gross and teeth sensitivity lasted a couple days, but teeth are a pale-yellowish-white(sometimes very white in artificial lighting). instead of the yellow caused by 5 years of braces and innumerable amounts of snacking on sweets. sis is now using them. her two front teeth are blinding white. ha ha. she wonders why the strips don't extend to cover the back teeth. wondering, wondering.... actually the dentist next to the place i work, gives out samples of stronger stuff so that's the reason why i tried them. so all you adults over the age of 40, get rid of that nasty coffee stain on your teeth.
