Oral-B's Bluetooth toothbrushes with the Oral-B app shows a mouth map and tells you where you're missing. Available at almost all major retailers. PS - I don't realistically think people will use Oral-B's solution daily, too awkward (requires sticking the phone to a mirror/face alignment), but useful for "spot checks."
