To follow the idea of a reason to smile, you don’t want the Twinkles to show all the time. Grab your mirror, smile slightly, do not laugh, and see how much of the canine or second tooth shows. Pay attention on where the lip ends, now sfind a placement where the jewel shows, as far back as possible, low down on the tooth and off center, forward on the canine or back on the 2^nd tooth. Of course the last say lays with the bearer but good advice is always appreciated.
