This young lady has visited me with her mother; the main problem was that the upper milky tusk remained after the permanent nebula had partially appeared behind it.

By examining the case, I noticed that there was also a reverse bite on the canine on the opposite side.
The case was successfully treated with fixed metal braces and after the deciduous canine was removed the permanent canine was pulled back to its proper place, and our little friend can smile confidently again.
