buck teeth, overbite, used to be a worse overbite before I was stuck in braces for 5 years. My overbite wasn't just an overbite either, I had a deep overbite, meaning, my front teeth covered my bottom teeth and my bottom front teeth used to hit the roof of my mouth.
Also doesn't help the appearance of my buck teeth that I have tmd/tmj (not as bad as it used to be) because my teeth didn't come together right after having too many teeth were removed, and also, that I grinded my teeth down quite badly from being on lots of adhd medication (yes, it is a side effect). So essentially, except for my two front teeth, everything else is scraped pretty flat.
