The color of the tooth is genetically determined and is influenced by factors such as: age, eating habits, smoking, consuming coffee or tea, taking medication, teeth injury (particularly in the front teeth of the upper jaw), old prothetics. The whitening of teeth is a procedure through which we improve the color and brightness of the teeth without damaging their natural appearance. We took pictures ,at our dental clinic, before and after this operation, so that we can  release the difference in color.
