Q. I am 24 and have had a child premolar extracted (top left, the premolar closer to the molars) three months ago as it was mostly fillings and there wasn’t much tooth left. I don’t have an adult premolar to replace this, though I have been told I can have an implant in the gap. However, as my upper incisors overlap, I was wondering if I could get a 6 month or invisibrace that would straighten out my teeth, and reduce the gap. I know that these types of braces can straighten the teeth, but are they appropriate to help reduce the gap if I have a tooth missing? Many thanks!
