This patient had been prescribed an
antibiotic called tetracycline when she was a child. Unfortunately, it
was unknown at that time that the drug would be incorporated into the
teeth and cause a dark gray coloring. A technique called bonding was
used in her case. In bonding, the white composite material that is used
for filling cavities in front teeth was layered onto the front of her
teeth. As you can see the results look great initially, however, the
technique is not very permanent, and must be redone periodically. This
technique has now been replaced by porcelain laminates. |
