Cost of Dental Bonding for Black Triangles Because my Top Incisors Are Too Wide?

Black Triangles can be frustrating.  There are many reasons they occur as noted in all of the answers.  Usually it is because the bottom of the tooth is wider than the top of the tooth, forming a triangle which appears because the gum has shrunk away.  Solutions are as follows-1-Bonding the spaces closed by shaping the top of the tooth into a square instead of a triangle.  Easy to numb and pretty easy to do-Usually 450.00 per side of tooth.  2-We are experimenting with filler products like Juviderm infiltrated into the shortened papillae to pump up the gum and close the space.  Can be 550 total for all spaces.  Long term information  has not been determined. 3-If you have alot of space, sometimes you can do porcelain veneers/crowns to close the space as well.  Beware-Spaces can open up with time no matter what you choose.  Watch tooth picks and habits to keep the space heatlhy and intact.

Black triangles will form when the contact point between the teeth is greater than 5 mm from the height of bone between these teeth.  These black triangles can also form in the presence of periodontal disease.  But judging from the photo, your tissues appear pink and healthy and you look young.  I'm making a big assumption that you do not have periodontal issues.

The distance between the contact point between these two teeth and the bone height between these teeth can be determined with the help of a radiograph or the area could be anesthetized and the bone can be 'sounded' with a periodontal probe to get a very accurate measurement.  If this distance is greater than 5 mm (which I would assume it is), you will have the black triangle that is present in the photos.  This measurement is the first thing which needs to be assessed.

If this distance is greater than 5 mm, carefully bonding composite resin between the teeth can decrease the distance between the contact point and bone height.  Again, if this distance can be reduced to 5 mm or less, the tissue should fill in the triangle.  Another option, which is less conservative and carries a higher fee, would be porcelain veneers.  But, again, the distance between the contact and the height of bone is the key regardless of the restorative options.  $200-$250 per tooth for the bonding or $1000-1250 per tooth for the porcelain veneers is a fair price in my area.
