One last note is that both Crest and Colgate recommend continued usage or their products to improve your teeth whiteness level. Therefore, if you are satisfied with your initial results, consider purchasing another teeth whitening kit to whiten your teeth even more. However, neither Crest Whitestrips nor Colgate Simply White Night can give you a ?bombshell? white smile if you have had years of coffee, caffeine, or smoking. For those results, you will most likely have to have multiple visits to your dentist as well as spend hundreds of dollars. If however, you are looking for a cheap alternative to whiten your teeth several shades, then why not give at home teeth whitening products a try? After all, almost all of them offer a money back guarantee.
