The graphics are amazing, the controls are great, everything about this game is awesome. It is a good time killer when you're on the road, (I only got a headache once) and it is awesome to play when you're bored. Keep up the good work and I'm hoping for a Piano Tiles 3. April 9, 2017.
An underbite, clinically called prognathism, is the malocclusion or bad bite that happens when lower teeth overlap the upper teeth. Severity can vary between a mild underbite, where the two rows of teeth almost meet; and a situation wherein the teeth don't meet at all because the gap is so wide.
Your overbite is how your front teeth overlap in a vertical fashion. This can be normal, open, or deep (where your lower teeth are up and behind your front teeth and less of them is visible). Whether it needs fixing and how is something your orthodontist decides.
