Many people understand the concept behind teeth whitening. They know that our teeth collect stains through the years. The now that teeth take on pigments from coffee, some fruits, wine, and other pigmented sources. They also believe teeth whitening removes the stains. However that is a misconception.
Teeth Whitening Removes the Natural Pigment in Your Teeth
While teeth whitening removes the pigmented stains, it also removes the natural pigment in your teeth. This can be illustrated by explaining shade guides.
Teeth Whitening and Shade Guides
In dental school, dentists learn about shade guides, a tool with a full spectrum of natural teeth colors which a dentist may see in natural teeth. When he or she needed to match a patient’s natural tooth color for a crown, or some sort of unnatural tooth, the dentist could always refer to the shade guide.
Teeth whitening gained momentum in the 1990s. When people would be in need of porcelain crowns, the color of their natural teeth would be much whiter than that on the shade guide, because they’d been whitening their teeth. Therefore, the manufacturers had to adjust the guide, to allow for the whitened colors.
Experienced cosmetic dentists will use the revised shade guide, as they often have clients who have teeth whitening done on their teeth. However, general dentists typically only consult the original shade guide. Therefore, a patient who has had his or her teeth whitened, who visits a general dentist, with less cosmetic experience, runs the risk of crowns or veneers not matching the natural pigment in their teeth, because even the whitest shade on the guide could still be darker than whitened teeth.
The Amount of Whitening Caused By Teeth Whitening
The results of dental studies indicate that the longer your whiten your teeth, the whiter they will become. However, the longer someone uses the bleaching gel, the amount of whitening will actually begin to decrease, causing most people to hit a point where they stop. Some people will whiten their teeth to the point that they seem to glow. It is all a matter of preference.
