How long will i have braces on for?

Depends: Malocclusions (bad bites) are like snowflakes, no two are alike. Best advice, make an appointment to see a fully qualified Orthodontic Specialist for an initial examination (usually free). Orthodontist can then determine the extent of your problem, what needs to be done to correct it, and what treatment modalities (and costs) are applicable to resolve your individual malocclusion.
