Q. Hi, i am considering having veneers to the the upper front jaw. i have spoken to my dentost and he said that i would only need the first four done. I am really nervous about getting it doen but it’s something that i really want done. i hate my smile and am very concious when i smile. I had a bad experience with my last dentist as a teenager and as a result of poor comunication i have been left with a crown on my front tooth. it stands out to the other teeth and there is a black line along my gum where you can see the join. Is there something i can do about this and also if i had veneers would they all develop this line in time? Please help?
