  Use teeth-whitening toothpastes. These toothpastes have bleaching agents like hydrogen peroxide. Brush teeth for two minutes using a circular motion. Brushing teeth twice a day will yield the fastest results.

  Apply whitening strips to the front of teeth. You can use teeth-whitening strips alone or in conjunction with the whitening toothpaste. All whitening strips have a bleaching agent, along with adhesive that binds the strip to the teeth. In most cases you place the strips on the teeth and leave them on for 30 minutes to an hour. Use the strips twice a day to get teeth whiter in three days.

  Use a mouth guard kit. These kits come with ingredients to make an impression of your teeth. Once the impression hardens, you place bleaching gel in the center of the impression and place this impression or mouth guard over your teeth. Some brands instruct you to leave the mouth guard on for 1 to 3 hours, while other brands direct you to leave the guard on while you sleep. After the prescribed time is up, remove the mouth guard and rinse your mouth. Use a mouth guard once a night for three days. You can use the mouth guard kit alone, or with the whitening toothpaste and/or whitening strips. According to Good Housekeeping, mouth guard kits and whitening strips are the two best ways to whiten teeth at home.
