How long should I wait to get my two front teeth contoured now that my braces are off? (photo)

I got my braces off after 2.5 years of treatment as an adult; never had them as a child. My orthodontist did a lovely job at straightening and aligning my teeth (considering what he was working With/how bad they were before) However, I have always disliked the shape of my front two teeth (more round and large than the rest of the teeth), and was wondering how long I should wait to see a cosmetic dentist for dental contouring? (I.d. Do my teeth need to "settle" etc)
