David, The "crookedness" of your smile is in your facial muscles that lift your lips and cheeks. You say that it has always been like that. Are there others in your family with the same smile? Since it bothers you I am sure that you have stood in front of the mirror and practiced lifting the right side of your smile. If you are able to force the right side of your smile up to even it out, I would suggest practicing it to strengthen those facial muscles. That procedure is free. If you are unable to lift the right side of your smile no matter how hard you try then you likely have some problems with the nerves that tell those muscle to work fully. I would be very slow to consider facial plastic surgery to "correct" it as it may then make your face look crooked when you weren't smiling. Lastly, when physical imperfections are not predictably corrected we can change how we see ourselves and smile with every else we can from inside out. Perhaps we can still light up the world around us with our uniqueness.
