How long does teeth whitening last?

The longevity of the whitening process depends on the individual’s lifestyle. For those who don’t smoke, reduce their coffee and tea consumption, and maintain regular oral hygiene, the effect can last for 1-2 years. However, for those who smoke or consume excessively colored beverages, this period can be shortened to a few months. Regular dental checkups and minor touch-ups, if necessary, can increase the longevity of the whitening effect.
