    The length of time it takes to whiten your teeth will vary with the amount of discoloration of your teeth. For treatments performed by your dentist, it generally takes 30-90 minutes per visit to make your teeth brighter. It may require as little as one visit and up to ten visits over a period of time. Over-the-counter products may require you to wear a mouthpiece anywhere from 30 minutes a day to  overnight for up to a month.
