Dental teeth whitening is a cosmetic dental procedure that involves using various techniques to remove stains and discolorations from teeth, resulting in a brighter and whiter smile. There are several ways to achieve teeth whitening, including in-office treatments performed by a dentist, take-home kits provided by a dentist, and over-the-counter products.
In-office teeth whitening typically involves the application of a high-concentration hydrogen peroxide gel to the teeth, which is activated by a special light or laser. The treatment usually takes about an hour to complete and can result in teeth being several shades brighter. Take-home kits provided by a dentist often involve the use of custom-fitted trays that the patient wears for a specified amount of time each day for several weeks.
Over-the-counter teeth whitening products, such as whitening toothpaste, strips, and gels, are also available. However, these products typically contain lower concentrations of hydrogen peroxide and may not be as effective as professional treatments.
