Long before the at home teeth whitener became an option for the general public, the only way to whiten your smile was to visit your dentist. In a procedure that the ADA (American Dental Association) calls “chairside bleaching,” your dentist uses a bleaching agent and applies it to your teeth, using a gel-like substance to protect your gums. This procedure typically takes 30 minutes to one hour. Sometimes, a light is used to increase the efficacy of the bleaching agent.1 Even with the availability of the at home teeth whitener, chairside bleaching is still a popular option for some people.
At Home Teeth Whitener from Your Dentist
In recent years, at home teeth whitening has taken off. One method first requires you to be fitted for a custom mouthguard/tray by your dentist. Once your tray is ready, you also purchase a bleaching solution from your dentist that usually contains carbamide peroxide. Then, from the comfort of home, you use the solution in conjunction with the tray to whiten teeth through either overnight treatments or daily treatments, depending on the product.
A Simple At Home Teeth Whitener
Whitening toothpaste is also widely used as an at home teeth whitener. Whitening toothpastes generally use silica or other mildly abrasive materials to polish away stains and otherwise mechanically remove the stain from tooth enamel. Today, teeth whitening strips have become a popular at home teeth whitener, and other products such as oral rinses are being made with teeth whitening agents as well.
