I had braces during my preteen years for about 3 years. I am 24 right now and I don't like my smile. I have somewhat of a narrow mouth with average teeth... I was told my one dentist I can replace/add on my front 6 teeth to give me a bigger smile (porcelain, lumineers etc) , but I am wondering if I have other options, such as using something to make my jaw bigger or expand my upper teeth more.
