I can only assume that Chris Maddison takes excellent care of his LEGO teeth because these chompers appear quite healthy! Just look at those pearly whites (modified 2×3 pentagonal tiles). Firm-looking rosy gums and not a cavity in sight! (I bet money he even flosses.)
The best part about these LEGO teeth is that they even chatter like the wind-up plastic toy Chris’s design was based on. Check out the video below to see for yourself.
