When it comes to teeth whitening, there are many clinical and over-the-counter options on the market. This includes: • In-Office Tooth Whitening. This procedure is completed by your dentist using bleaching solutions and/or lasers that work at a much higher intensity than over-the-counter products. This allows for a deeper whitening that occurs more quickly.  • Tooth whitening strips and gels. These products are applied directly to the teeth using either a brush or a strip. These products are typically peroxide-based and need to be utilized 2-3 times a day for approximately 2 weeks. • Tray-based tooth bleaching systems. With this option, a tray is filled with a peroxide-based bleaching gel is placed over the teeth. This is typically done for 30-60 minutes a day for up to four weeks. These systems can be purchased over the counter or at your dentist’s office if you’d like a more custom fit for your tray. • Tooth whitening toothpastes. Whitening toothpastes contain chemical agents that help remove stains from teeth. These products are relatively inexpensive and brighten teeth minimally but can provide a subtle whitening.
