I have these spaces between my teeth from gum recession and gum shrinkage. I think the spaces are called “black triangles.” I absolutely hate them and don't smile like I used to. I'm in the process of getting gum grafts but the grafts definitely will not fill in the black triangles. I've heard that black triangles are harder to correct than just regular spaces (diastema). Will veneers or bonding take care of this problem? Any advice as to what I should do? I want to take care of this problem once all of my gum grafts have healed. Thank you for any insight!

Dear Quiy,
Yes, the black triangles are a difficult esthetic problem. The access and the geometry of this type of esthetic case make it very demanding. But if you go to an expert cosmetic dentist (and the ones we list in the Dallas-Fort Worth area are all terrific) they can fix that. It's hard for me to say what would be best for you–it depends on the shape of your teeth, the condition of your gums, and other factors. Porcelain veneers are a possibility, direct bonding is another possibility.


Don't trust your smile to someone who merely claims to be a cosmetic dentist. Go with the real thing for this one.


My advice.

Good cosmetic dentistry requires special skills and extensive training beyond dental school.

There is a great difference between a good, reputable general dentist who thinks he or she can do cosmetic dentistry, and an artistically inclined cosmetic dentist. If the appearance of your smile is important to you, you need to understand this difference.
