Q. Hi, im a 21 yr old male that had braces to fix a slight underbite when i was 14-16, for 2 years after i had my braces off i started noticing my perfect bite was becoming more uncomfortable. As of now, im 21 and have an edge to edge bite, my mandible grew, but i dont have an underbite yet, just edge to edge which is very uncomfortable. Im assuming i will have to go back to braces and elastics again, but i was wondering if invisalign will work for my situation? Can I use elastics with invisalign, I read online that invisalign can fix underbites?
