It’s been about 3 years since I finished orthodontic treatment in 2020, and it’s been fine without any major widening. I had 8 teeth extracted in total: 4 impacted wisdom teeth and 4 molars. I was really worried because it was a factory-style dental clinic, but I’m relieved that the prognosis was better than expected. People around me say it could collapse later in my 40s or 50s, but for now, I’m very satisfied because it looks better aesthetically.
But the waiting time was extremely long, and the actual treatment was basically over in 30 seconds.
