Hi. As I understand your problem is too much of gums showing when you smile which are dark in colour. There are procedures to make that more pleasing in appearance such as crown lengthening, lip repositioning and orthodontics. The darkish colour at the margins may be because of improper positioning of the caps or pigmentation, both of which can again be corrected. However, changing your caps from metal ceramic to full ceramic will help only if you are dissatisfied with the colour of the crowns or feel the metal darkness shows through at the margins. My advice would be to consult a prosthodontist for the crowns and a periodontist for the gums. Good hands from multiple specialities may give you the best smile.
