How Whitening Works

Bleaching gel used in the teeth whitening process is usually composed of hydrogen, carbamide, and peroxide that breaks down into oxygen molecules. The molecules seep into the tiny pores of enamel and dentin, breaking up stains that block out light. As the stains are broken into smaller and smaller pieces, more light travels through the teeth making them appear lighter.

Results vary depending on the bleaching gel used and the amount of time it is worn. Sometimes results can be seen in as little as one night, or depending on the severity of the stain, can take up to several months. Results can also vary on the degree of your stain. The darker you stain, the longer it may take to remove the stain. Check with your dentist!
