Teeth whitening procedures are used to brighten the appearance of a patient’s smile – sometimes by as many as 5 to 10 shades in a single session. Teeth whitening procedures have become some of the most popular aesthetic dental treatments among patients. Professional teeth whitening services can be performed in an office setting or prescribed for take-home use by a patient. In comparison to over-the-counter teeth whitening treatments, professional whitening uses stronger whitening agents that deliver faster and more effective results.
