Lily, another invention with serious bite! Communicating can indeed be very tricky, if you're a newborn baby, speak a different language or like the late Stephen Hawking, physically not able to - so your invention could make a huge difference to so many people across the world. I now imagine tiny babies with big teeth, which is quite bonkers! But I also wonder about the more serious sides to your invention: our mouth and the way we speak can be affected by our jaws so could it be that a set of teeth could act to help people? I hope someone follows up on your excellent thinking, Lily.... keep inventing!!
