Up to you. Personally, absolutely no way would I ever do that. I have braces, and i've been recommended extractions tons of times by ortho's I enquired with and the ones I've worked with, but I still won't do it. Orthodontists generally still believe a small mouth and crooked teeth is due to genetics when it isn't. It's enviromental and to do with what we do as we grow up.
You need to correct your tongue posture, and body posture (look up mewing, oral posture, etc), which will slowly expand you pallet naturally. If you can get adult pallet expansion that works, great. That's better than ripping things out of your head which were supposed to be there (despite the BS orthos will say). They mostly all recommend extractions because they don't understand why the mouth is too small and want to rip your teeth out so they can charge you for it and use braces to smash your teeth back into your face which constricts your airway leading to health problems. and makes you less attractive.
Despite all the orthos recommending me extractions of 4 teeth, I'm also nearly there with no extractions. I'm going to change ortho again to someone that will finish my case without constantly banging on about extractions. I know it's possible. I'm almost there when they said it wouldn't happen. So, there's my take.
