I want to have my teeth filled, but it's contradictory. What should I do?

What's so ugly about whole teeth? I have been taking the exam for two years, and I didn't choose until after the college entrance examination. Students are used to you and you won't say anything ... It doesn't hurt to lose a tooth or pull out a tooth, but it hurts a little when anesthetizing the gums. Then it will hurt for a week after wearing braces, because the teeth have started to change seats. It's quite comfortable to look at your beautiful teeth now. Oh, yes, make up your mind and do it quickly. It would be better if you did it earlier. I hope I can help you.
