I'm a 25 year old female and I have an overjet of around 10mm. I have had lingual braces for 9 months and my orthodontist told me the only way he could reduce my over jet is by doing ipr however I don't know if that will make enough of an improvement to be worth doing. Also I think my smile is fairly narrow and I'm worried that ipr may cause it to look more narrow than it already does. Is it possible that this could happen? I would like to know if it's worth risking having ipr done?
