The length of treatment is determined by the severity of each specific case. If there are bite issues, it is sometimes easier and quicker for traditional braces to correct. Although Invisalign has come a long way with what they can do, braces are still the standard in orthodontic treatment. If the case is a simple one, with minimal correction, Invisalign can be the quicker treatment. It really does depend on what your final goals are for your smile. It is a great idea to always find out all of your options and get the orthodontist’s opinion on what would be the best for you. – Becca
