How Does Teeth Whitening Really Work?

Teeth’s whitening has become a norm for most people. Everyone has a goal of having brighter, whiter teeth and the gels, strips, and toothpastes all promise to help people achieve that goal.

While people understand that using these teeth whitening products will help brighten and whiten teeth, they do not understand the process behind it. The following is a look at exactly how those pearly whites become white again when undergoing a teeth whitening procedure in San Diego.

The Basics of Teeth Whitening

It may appear as if teeth whitening magically remove the discoloration from teeth to make them brighter and whiter, but that is not how it works. The basic idea behind teeth whitening is that the products used remove or erase stains on the teeth. It is the stains on the teeth that is causing the discoloration/yellowing and preventing you from having bright, white teeth.

When undergoing a teeth whitening procedure at a dentist office, the dentist will use a gel that is specifically designed to lift the stains off the teeth. The gels typically contain one of two types of chemical cleaning agents that will work to bleach the teeth and make them whiter.

The Process of Teeth Whitening

Getting your teeth whitened is a pain-free, quick procedure that can be performed in a single office visit. The dentist will typically clean your teeth and gums before administering the teeth whitening procedure.

After the teeth/gum cleaning, the dentist will place the teeth whitening gel on the teeth. The gel is left on the teeth for several minutes. This allows the chemical agents that will bleach the teeth to work their way into the porous tooth enamel. Once it works its way into the enamel, it will spark a chemical reaction that dissolves the stains on the teeth.

Dental teeth whitening procedures have been proven to successful whiten teeth. When the procedure is complete, you can expect to have teeth that can be anywhere from 5 to 20 shades lighter.

What Causes the Staining on Teeth?


Teeth discoloration is a natural part of the aging process. Over time, the bright white color of the teeth slowly starts to fade. This is a direct result of the outer layer of enamel wearing away. When it starts to wear, the white color of the teeth starts to fade.

While teeth discoloration is a part of the natural aging process, there are several things you do on a daily basis that enhances or speeds up the discoloration process. The foods you eat, the drinks you sip, and dental hygiene all can cause the teeth to stain and yellow.

Some of the most common causes of teeth staining or discoloration include:

• Drinking teas, coffees, and wines
• Eating certain fruits – apples/potatoes
• Using tobacco products – cigarettes and chewing tobacco
• Some medical conditions
• Medications
