I had a bit of a rabbit tooth so I wanted to correct it without overdoing it, but I thought it wouldn't have much of an effect since it was a partial correction, but somehow it felt like it straightened out my face shape!!! I received a lot. I lost some facial fat, but my rabbit teeth were corrected and I was really satisfied with the partial correction! Oh, and those who have braces may really want to take off their braces, but when you take off your braces, your real teeth have a tendency to return to their original state and move easily, so I recommend that you hold on and keep them on for a long time..!
