I'm 37, and I have a large overbite. Am I too old to fix my teeth or is it something that can be done? (Photo)

I agree, something can always be done. It looks like the only way to achieve an ideal result is to have brace treatment, in combination with jaw surgery. If you would be happy with an improvement, then you might get this with just braces - but this would not close the bite completely. I would see a few orthodontists, as some will only give you an all or nothing treatment plan. I hope this helps! 

With such a large open bite, there are definitely things that can be done to give you some improvement. You would need to contact a very good orthodontist. He will go over with you what your options are which will most likely include some jaw surgery and he will get an oral surgeon involved to give you the best outcome. Don't let the word surgery frighten you away. Get a consultation with the orthodontist. Good luck.

Yes of course you have options to create an even bite for you and of course a natural looking smile. You need to take a complete Xray set and send them to your dentist so they can design for you a new smile and make a plan. You can improve your smile for sure , please visit an orthodontist. Hope this helps.
