Is it better to whiten my teeth at home or at my dentist?
Ideally, bleaching should be done under the supervision of your dentist, who is in the best position to understand your overall oral health. Dentists can also prescribe in-home treatments. Over-the-counter products (non-prescription) are an option. The main difference between in-office and over-the-counter bleaching products is the concentration of the active ingredient. In-office products contain a higher concentration.
