At-home kits typically involve using a whitening gel that is applied to the teeth using a tray or strips. The tray or strips are worn for a certain amount of time, usually about 30 minutes to an hour, for several days or weeks.
Professional treatments, on the other hand, are usually performed by a dentist or dental hygienist. These treatments may involve the use of a stronger whitening agent and may be done in a single office visit or over the course of several visits.
It’s important to note that teeth whitening is not permanent and the effects may only last for a few months to a few years. To maintain the whiteness of your teeth, you may need to repeat the whitening process or use at-home touch-up kits. It’s also important to maintain good oral hygiene habits, such as brushing and flossing regularly and avoiding foods and drinks that can stain your teeth.
