For almost 50 years I've practiced the no teeth smile, so photos are no big deal, and tv only occurs once a decade or less...
My dad was the same way. Our teeth came before his. He got his veneers at about 50 years old. Now he has the biggest shit-eating grin every single time you see him. Makes me so happy. you can't put a price on things like that.
Do something about your teeth. Then spend the rest of your life smiling.
