I do it the Japanese way, but I do need to see if P&G or J&J make the toothpaste I use when I eventually run out (I buy in bulk) and need to refill. Oddly, US toothpaste is an oft-requested gift when bringing things back from the US. My best guess is the formulations in some such as for whitening can’t be sold here legally (but, as with many things, buying/importing for personal use is not illegal).
