This is a form of normal dental development so no treatment is indicated. Note in the OPG dated Sept 2013 that the upper left adult canine tooth appears to be angled too far forwards. No treatment was undertaken though sometimes the baby canine tooth is removed to encourage the adult tooth to improve its position.
Note that the teeth appear to be in quite a good position without any treatment. If the patient wanted to improve the straightness of the teeth this can be easily undertaken now or in the future with invisalign, braces or similar.
