I feel like my teeth are smaller on one side. Is there an alternative to fixing that aside from veneers? (Photo)

It's hard to tell with the braces in place, however to me it looks like your teeth might be similar in size -- and the difference is how much your gums cover your teeth.  Sometimes in braces, your gums will grow down over your teeth a bit and make your teeth look smaller.  To me you look like a great candidate for gingival contouring (a minimally invasive, gentle laser procedure) after your braces come off.  I do this for most of my post-braces cases as it makes the smile bigger and more symmetrical.  Follow that procedure with whitening, and you should have the smile you've been patiently waiting to show off :)

Hi:For best long term results I recommend porcelain veneers, however, you can definitley start with bonding and do veneers later.Best,Dr. Maddahi
