Also, how about a forum for “where’s this thread?” or perpetually re-asked questions? It could be called “It’s Been Done Before” (IBDB).
Is this what you’re looking for?
Yes! For some reason the search engine utterly failed to find these when I had it look for “teeth”, “tooth” and “whitening”. Thanks!
Never a problem for another Doper. BTW, I just had it search for “tooth whitening”.
