There are a number ways to get your teeth whitened these days-and for a variety prices. If you're looking for a quick way to whiten teeth, go for the laser whitening. This can range anywhere from $200-$2000-but be sure to check with your dentist to see if laser whitening is right for you! There are many in-office treatments that start in the dentist's chair and are brought home to complete, such as a nightguard. This can be worn anywhere from three hours to overnight. This is a more gradual whitening process and can cost anywhere from $100-$300. Other whitening products can be found at your local pharmacy for under $50, such as gels or white strips. In addition, there are several brands of teeth whitening toothpaste and flosses.
