Whitening 101

When comparing teeth whitening options, it helps to understand a bit about how each of them work. There are a few basic techniques that remove stains from tooth enamel and enhance its bright white color:


You are probably already familiar with hydrogen peroxide – that medicine cabinet antiseptic you use to clean minor cuts and scrapes. Hydrogen peroxide can remove stains in the same way it kills germs, by breaking down compounds that cause discoloration. This process, known as oxidation, is also how bleach turns clothes white. Dentists frequently use carbamide peroxide, a mix of hydrogen peroxide and urea, which is easier to apply to teeth.

Essentially, the higher the concentration of peroxide, the faster and more robust the results will be. Whiteners at the dentist’s office are stronger than those for home use, but over-the-counter products still come in several strengths. Not every supplier readily reveals their products’ strengths, however, so beware ones where you don’t know what you’re getting.


A long-used and inexpensive method, many whitening toothpastes include abrasive ingredients like charcoal or baking soda. These physically scrape off surface stains while you brush your teeth. However, too much abrasion over time can wear down your enamel as well, leaving your teeth prone to further staining.

Blue light

If you’ve ever had more than a routine cleaning done at the dentist, you’re likely familiar with blue light treatment. When they’ve finished filling a cavity, adding sealant, or attaching braces, they help the resin set by shining a blue light onto it. These same blue LED lights can also enhance the oxidation process, making whitening with peroxides more effective.
