What is Best Fix for Black Triangles Between Teeth? (photo)

Porcelain veneers are your only option to correct this.  I would also have your doctor perform a small amount of recontouring of the gums on a few teeth for symmetry.  I would look into some financing options that may help you in being able to afford it.  Best of luck.  

The most economical way is with white fillings material. You have natural larger two front teeth already, anything you do will cause your two front teeth look even larger.  The solution here is to replace that black triangle with white materials to eliminate that black triangle appearance.  How much you want to spend will dictate which material to use (i.e. porcelain or fillings).  Another option is gum surgery.  There a lot of newer techniques where dentists can release your gum tissue and bring the entire gum curtain downward, but this technique result can be unpredictable where using porcelain and white fillings results are more predictable.

Doing a small amount of bonding on both teeth (for symmetry) would likely be the best way to minimize the black triangle appearance.   In this situation, it might lend to the tooth looking a little more 'square'.  Another option to look at is getting Juvaderm to augment and bulk that tissue up.  

The unsightly "black triangles" that form between your teeth are usually due to gingival (gum) recession or resorption of the gingival papilla or gum tissue that fills in that space between your teeth. Here are some ways to fix that:

1. Make sure you do not have ongoing (active) gum disease. Periodontal (gum) disease causes this problem by triggering gum recession and, the more serious to treat, bone resorption. The black triangles will only get larger if your periodontal condition is not stable.

2. Have your dentist check your labial frenum attachment. This ligament under your upper lip tends to attach lower against the gum between your upper two front teeth worsening the "black triangle" problem. It can be repositioned higher (by a minor gum surgery) to alleviate this problem and insure a better treatment result to fix it.

3. Gum/Bone grafting is an option, especially if there is a loss of bone between the teeth that has caused the lack of support and corresponding gum recession. A gum graft alone may not be successful if there is not a corresponding augmentation of the supporting bone.

4. If your periodontal condition is stable, some minor composite resin bonding can be done to build out the adjacent teeth to close most if not all of the space. However, this can be problematic if your gum tissue remains inflamed and if the bonding does not allow for a "cleansible embrasure" which is an important part of your periodontal (gum) maintenance. But beware: composite bonding can also alter the shape of your front teeth, making them look "boxier" and less feminine looking. 

The best news is that you stopped smoking which is a major contributor to periodontal disease and the corresponding gum recession which most probably caused the "black triangles" to appear. 

A very conservative and cost saving approach would be to have properly contoured and polished bonding added to the teeth in the "black triangle" areas.

The Bioclear Method can fill in the spaces without placing veneers.  While veneers work very well, a conservative solution is Bioclear.
