How Long Do Whitening Effects Last?

It is not permanent.The duration of teeth whitening effects can vary depending on the food and beverages that cause staining and also the individual's oral health. In-office teeth whitening performed by a dentist typically provides the longest-lasting results, with the effects lasting up to several years. This is because the treatments are stronger and more concentrated than over-the-counter products and can penetrate deeper into the tooth structure. The level of whiteness will range from person to person depending on the state of the teeth, the amount of staining, and the type of bleaching system used.
