Typically, Dental whitening can last from six months to two years. However, this timeframe can be influenced by factors like your oral hygiene practices, dietary choices, lifestyle habits, and the type of whitening treatment you opt for.

Maintaining good oral hygiene, including regular brushing and flossing, steering clear of foods and beverages that can stain teeth, such as coffee and red wine, and scheduling routine Dental check-ups and cleanings can help extend the effects of whitening.

Moreover, the type of whitening treatment you undergo can also impact the longevity of the results.
