[Protruding Mouth] Review of protruding mouth correction

I'm still using it, but I'm using it. I am in the process of correcting a protruding mouth after extracting 4 teeth, and among the places I went to get estimates, the price was the cheapest and there was no monthly fee, which was good, and there were many cases of protruding mouth. However, I was worried because it was so cheap, but there are a lot of employees and customers, so it is a bit hectic compared to other dental clinics, but it has been going on for a year and a half without any problems.
