In order to get a definite effect, I had 4 teeth extracted
at the recommendation of the dentist.
It was for cosmetic purposes, so I was very satisfied with that.
However, as a side effect of the orthodontic treatment, a very small black triangle
was created
. The orthodontic device is attached to the back of the teeth, so I have to wear it for the rest of my life.
However, it is not particularly uncomfortable.
