I currently have MetLife Dental which does not inlcude orthodontist coverage. I went to an orthodonitst and was advised to get invisalign to keep my teeth from gapping. Two years ago, I had molding applied to my two front teeth to close the gap and it worked and was wonderful. However, my teeth are gapping apart again. The orthodontist stated that Invisalign is the best alternative to permanently close and stop the gapping because my teeth are very straight and do not have an overbite. Is there any insurance provider who offers orthodonist coverage to adults or do you know of any discounts available?
