First of all, I had extraction orthodontic treatment to improve protruding mouth (they said it was a gum-protrusion type), and I had 4 teeth extracted. At first, my protruding mouth was such a big complex that I asked them to make my mouth go in a lot, but they told me in advance that if they did that, I could end up with a sunken, toothless-looking mouth and it might look bad
As the orthodontic period got longer, my facial skin and muscles were stressed too, so I lost a lot of muscle and lost cheek volume, and enduring that process was really hard So in the middle, I couldn’t take it and got cheek filler too
In conclusion, extraction orthodontics should be considered carefully, because your impression changes so much. Compared with before, my mouth went in and it does feel more refined, but I can look older and severe cheek hollowing can happen. Your impression changes, but whether that change will be good or bad is something you can only know after doing it, so I think you definitely need to consider that
