Invisalign and Braces both have the same effect of straightening teeth and improving conditions like overbite where the teeth are misaligned.
Braces have the disadvantage of exposing metal wires and rubber bands along your teeth which might simultaneously hurt teeth when chewing certain types of food. Another major disadvantage is that it is irremovable until done so by a dentist. Braces have the advantage of being more flexible than Invisalign in fixing teeth posture as it can move teeth vertically and improve bridgework dramatically. Braces don’t have to be cleaned regularly as the metal surface kills bacteria with metallic charged ions.
Invisalign’s benefits range from the fact that it is invisible, removable, and it stems from a BPA-Free clear plastic product. Taking them off might make the teeth alignment process take a while longer, although they can be cleaned effectively with Invisalign’s cleaning system or rinsing with luke warm water. Invisalign also has been effective at straightening alignment faster than braces.
The follow-up visit times to the dentist for both treatments are about the same.
From these facts, it seems like Invisalign’s better for big eaters and people who want a break from constant teeth treatment, although braces is a long-term teeth alignment process that can rotate canines and fix tooth derangement.
