Teeth Whitening // The Science
Thousands of people pursue teeth whitening procedures every year, but very few of them understand why the bleaching solutions actually make teeth whiter. While you don't have to understand the science behind teeth whitening in order for it to work, this understanding will help you make better decisions about your oral health.
The purpose of the teeth whitening gel is to break up the substances that create stains on the teeth, essentially lifting them out so that light can shine on the actual surface of the teeth, rather than the stain. This permits more light to pass through and creates a whiter appearance.
The peroxide molecules are small enough to enter the miniscule crevices in the teeth where stains are usually found.
The amount of time it takes teeth whitening gel to work depends on its concentration and how long it is left on the surface of the teeth.
When you undergo laser teeth whitening, the laser is used to activate the gel further and results in more targeted results. Your gums and lips are covered during the procedure.
The laser acts as a stimulant over the gel, and this procedure is more effective against tough stains, such as those caused by tetracycline.
The science behind teeth whitening is not complex, but it will help you make informed decisions. For example, those with sensitive teeth and gums might not want to have professional laser teeth whitening because it can cause additional pain.
