Exploiting The Recession: A Mom's Trick to Whiter Teeth
Cathy's discovery works wonders for consumers wanting whiter teeth without breaking the bank. Having yellow teeth is embarrassing, can deeply affect your personal life and, like it or not, your career as well. People are turned off (in both a professional and personal sense) by yellow teeth. For years dentists have capitalized on this fact by charging exorbitant prices of $500 or more for "professional" teeth whitening procedures--most of which involve special tooth whitening trays with carbamide peroxide, and/or whitening "pens," that can turn the yellowest of teeth white. Products like Crest Whitening strips are certainly less expensive options (these products seem to hover around the $50-$80 mark depending on the exact treatment), but from our experience they usually don't get the job done. For decades the reality has been simple: if you want white teeth, you have to be willing to spend some serious coin at the dentist. Cathy, a mom from Santa Cruz, California, recently discovered a clever way of combining two different teeth whitening offers from two different companies--Dazzle Smile and Clean Whites--to get one full "super" whitening, comparable to what you might attain at a local dentist for $400 or more, using nothing but trial offers and paying just a few dollars in shipping charges.

How does the trick work? Basically, the idea is to combine the two different products to get one full strength whitening using just the trials.
