Joe Biden's Teeth is a silly website by 8 bit studios, whose purported aim is to "reduce our dependency on porcelain and metal fillings through the investment in clean and renewable enamel."
The disclaimer states that "Joe Biden is not affiliated with joebidensteeth.com, but we bet his teeth love it."
So it appears to be a mildly confusing publicity stunt by Trident... but then again, who knows. If you send in a picture of yourself smiling, Trident sends you a free pack.
The site is focused exclusively on Joe Biden's teeth. The tooth chronicles are especially cute, and have that mock-serious tone to it. You can play picture games guessing which set of teeth are Biden's. Or you can not bother. Whatever floats your boat.(From David B.)
