Many people view orthodontic treatment as purely cosmetic. There is however, another important factor with crowded or out of position teeth. This is the resulting food entrapment that occurs in all the nooks and crannies. Teeth are harder to maintain and keep clean, this winds up causing decay and contributes to the progression of Gum Disease. This results in loss of bone, which loosens teeth. Consider doing Invisalign not just for appearance sake, but also for the long lasting health of your teeth.
