Q. Hi, My four front teeth are posted crowns. I have had them replaced three times over the last 25 yrs, never with complete satisfaction (size, colour, speech etc). On my latest attempt to replace them I lost one of the smaller incisors and am now advised to have a six piece bridge from canine to canine or replace with implants. My concern this time is to achieve the best possible esthetic result and feel that a bridge would be more flexible in the smile design and retention of gum line. Can I please have your opinion on the esthetic merits of these two options? I have had significant gum and bone loss in the past though no gum disease at present and the situation is well maintained. I am also aware that a bridge will have a limited life span.,
