Do you have “dark triangles” around the edges of your teeth or along the gum line?
These are often the result of orthodontic treatment, misshapen teeth, gum recession, and even aging. Dr. Cain can help you restore beautiful aesthetics to your smile by closing these spaces with a modern tooth bonding process.
A modern alternative to tooth bonding, the injection over-molding process is not only a cosmetic solution for dental black triangles but also supports improved oral health by reinforcing the existing tooth structure.

Tooth Bonding FAQs
What can tooth bonding treat?
The modern tooth bonding process treats a range of dental concerns including:
- Changes in the gum line: Gum recession due to disease or aging can expose more of the tooth root and create the appearance of dark triangles over time.
- Misshapen teeth: If you have one or more teeth that are misshapen, rotated, or twisted we can create a more natural-looking smile by filling in open spaces.
- Post orthodontic treatment: For many patients, straightening teeth can lead to the appearance of dark triangles after treatment.
Am I a candidate for tooth bonding?
Most patients are candidates for this modern alternative to tooth bonding. Dr. Cain will determine the most suitable treatment options for your unique needs and cosmetic goals after a dental exam. Other restorative and cosmetic procedures for addressing dental black triangles can include dental crowns and veneers.
