Did anyone try to remove some teeth for the sake of beauty?

Yesterday, I went to the dentist to talk about my result from the screening test and my teeth model. He said that I would need to remove 8 teeth in order to make space for the other teeth. Wow. 8 teeth~~. I think the 4 out of 8 are the wisdom teeth which have not grown out yet. I'm 19, I'm not ready to lose that much. I noticed on the graphs that my last 4 wisdom teeth are the cause of my grown up teeth to lookout of place. Those wisdom teeth are pushing my teeth forward causing them to get out of the line which they supposed to stay. I asked the dentist "What if we remove just those 4 wisdom teeth and push the remaining teeth back and put them in place? I think this might work as well" . He said it could be possible, but will take years to push some teeth back to the heir place to the teeth line. My mom, who was with me, said that the doctor did mention that we will still have to remove other teeth. I do not want to remove the teeth I'm using currently. Because when we grow older, there will be a time we regret that we lost so many teeth for the sake of beauty. When we are older, we lose the teeth through ages. We would be wishing that we should have kept those healthy teeth which were removed for the sake of beauty. We would be needing them when we are older. My upper front teeth does not look bad when I smile. They look barely straight, but when you look from below, they are kinda out of the teeth line. The bottom front does no looks good. I'm glad that its just my upper teeth show when I smile. I think I should wait till 25? And see if I get any bad teeth that have to be removed. Its better to remove bad teeth than removing healthy teeth.
