Has anyone corrected the off-screen entry?

2nd year of orthodontic treatment... It's been a long journey... I don't have enough teeth and they're all spaced out, so I extended them outward, put the extensions back together, pulled the lower jaw that was in malocclusion to the right... Now all that's left is to put in one implant. Um... When I was in high school, I just went to the dentist in front of my house because I was busy, but now that I'm getting implants right in front of me, I wonder if I did the right thing. I'm so scared and I regret it. ㅠ ㅠ (Although other dentists I went to before said I needed implants...)
