I have 4 top-front jacket teeth (they are not porcelain and definitely not veneers) and I have these for 5yrs now. I am wanting to get my real teeth whitened or match them with my jacket teeth. Is it possible? I was wondering if there is a way for my bottom teeth to become straight or align them. Oh, sorry for the photo, it is not clear enough to see the color difference. Answers, tips and advise are greatly appreciated. Thank you.
