Well, I was in a rush this morning so I didn't brush my top left cuspid properly and then the last wisdom tooth has come up only half way through my gum. That's a serious penalty. They suggested I buy a motorised toothbrush - even recommended one. It's called "Super sparkle spinning plaque destroyer!™"
Pleth - I find that impossible to believe. I'm quite sure that your oral hygiene is, at the very least, on par, with the above-average Japanese person's oral hygiene. I mean, I don't know what these Japanese examiners are looking for -- but I'm willilng to put my money where your mouth is.
