Q. I want to have my teeth straightened and whiter. My teeth are slightly crooked on the left side and they are stained yellow, possibly due to my dietary habits (ie curries etc). I consider my lips to be my best feature but my crooked, yellow teeth ruin a lot of pictures and have made me very self conscious. I am almost 22 and I would like to have veneers but in. Would it be possible to do so at my age?,
