Can my gap close with a frenectomy then braces?

It depends: In many cases, it is better to close the space first with braces, and then undergo a frenectomy with the teeth held in their final positions. This is because in some cases, the scar tissue that may result can be as imposing an obstacle as the original frenal tissue. In other cases, it is necessary to conduct the frenectomy/frenotomy first, as the tissue can be an obstacle to tooth movement.

Yes: Removing the tissue that goes between the teeth and connects the gums to the lips removes muscle which is what is causing the space. Removing the tissue will cause the teeth to come together somewhat and the rest can be done with braces.

See an Orthodontist: A frenectomy before orthodontic treatment is contraindicated, and a post-treatment frenectomy should be attempted only if a continued tendency of the diastema to reopen and unresolved. See an orthodontist first!

The science is forever evolving. Current thinking is that appliances should be placed and forces applied to gently close the space. Frenectomy (surgical recontouring not frenum) should be accomplished as the space-closure mechanics are applied. Best done as team effort by specialist Orthodontist and specialist Periodontist.
