Worse than having teeth. Imagine having two giant teeth, but they’re built in there even more firmly so it sucks even worse if something goes wrong, and also they extend like half a foot or more outside your face. And you’re supposed to use it to eat? Fucking awful. Look at videos of toucans trying to eat. They’ve spent their whole lives practicing and it still looks awkward, like they’re doing their best not to fuck it up
There’s a few exceptions, like that YouTuber who rescues Toucans and keeps them in a huge aviary with outdoor and temp controlled sections. Or birds many many generations into captivity (I knew someone who did falconry and it’s more that the bird just decides to stick around in that case.) But yeah.
