Tooth Whitening
Performed in cosmetic dentistry, tooth whitening is the procedure
of making dark colored teeth whiter. White teeth in society is a sign of social stature, health, and youth.
But as we get older, our teeth need more care to maintain the whiteness we once had as a child. The enamel on
older teeth becomes less porous over time, or stained from tobacco use, coffee use, food, and other
bacteria.
To remove stains or lighten teeth color for cosmetic reasons, people can employ the use of tooth whitening
procedures at a dentist, or tooth whitening products purchased over the counter. Tooth
whitening procedures and/or over-the-counter products use oxidizers, which applied regularly over time, will bleach
and remove discoloration. Hydrogen peroxide is one example of an oxidizer. Oxidizers cross the enamel to bleach
stains that reside in both the enamel layer and the dentine layer under it. Tooth whitening can be accomplished in
two ways and if you're interested in lightening the color of your teeth, you should become familiar with both.
First, teeth color may be lightened by repeatedly covering the enamel with high concentrations of an oxidizing
agent.
This is the fastest way to obtain a set of white teeth, however because the dosage of bleach is very high, users
run the risk of burning soft tissues in and around the mouth. This burning is actually chemical burning occurring
from carbamide peroxide (the oxidizing agent). This agent must not be kept on the teeth for long periods of
time.
The second way to whiten teeth is to secure a less potent dosage of an oxidizing agent over the teeth for longer
periods of time (like overnight for example). This chemical is secured in one place with a mouth-guard and because
the chemical is less potent than that used for short periods of time, it's much safer.
In addition to the potential damage caused to soft tissues, other events could happened that surprise both
dentists and recipients of tooth whitening procedures. Some stains simply can't be removed from tooth whitening
procedures and/or over-the-counter products. Tooth whitening may also inadvertently bring out existing white spots.
And not all recipients of tooth whitening procedures accept the process in a healthy way. Some teeth become
sensitive after the process while other's teeth actually become darker. It's a peculiar but ironic phenomenon. In
an effort to make tooth whitening a quicker process, some dentists employ the use of light as a bleaching
accelerator, however studies have shown that this procedure can lose its effect thirty days after treatment.
For some people, it's only a matter of time (usually thirty days) before the results of tooth whitening
procedures and/or products fail (also known as "rebound").
Recent news reports have claimed tooth whitening as dangerous and some products on the shelves have been
removed. In Europe, some American tooth whitening procedures and/or products have been banned altogether.
You can examine the alternatives yourself and make your own decisions to see if it's something that you want to
do.
