Tooth whitening brightens your smile by removing stains and discoloration caused by food, drinks, or aging. It’s one of the most popular cosmetic treatments for enhancing your appearance, with two main types: vital whitening for teeth with live nerves and non-vital whitening for teeth that have had root canal treatment. Because whitening results gradually fade over time, occasional touch-ups are needed to maintain the brighter color.
