Everyone must have heard of teeth whitening in life, but do you know about cold light teeth whitening? Today, let's learn about it together. How long can cold light teeth whitening last? And how often should cold light teeth whitening be done? Let's learn together with the editor.

How long cold light whitening teeth can last depends on the cause of the patient's tooth discoloration. If exogenous staining, such as smoking, drinking tea or some special foods that are easy to stain, causes tooth discoloration, after cold light whitening, the patient's tooth color returns to normal, if the patient can maintain the corresponding oral hygiene in the future life, and try to eat less foods that are easy to stain, the color will last longer. However, if the patient's oral hygiene is not good, it is possible that recurrence may occur in a short time, perhaps one to two years, or even a few months. If the cause of the patient's tooth color is endogenous, such as fluorosis or tetracycline teeth, the effect depends on the degree of discoloration of the patient. If severe tetracycline teeth occur, the recurrence rate is very high, and cold light whitening needs to be assisted by other repair methods, such as all-ceramic veneers or all-ceramic crowns, to achieve a more lasting effect. Therefore, it is necessary to choose the corresponding treatment method according to the cause of tooth discoloration. Clinically, no treatment method will definitely last a lifetime. It may take a period of time for the corresponding secondary treatment, especially for cold light whitening.

Generally speaking, the whitening effect can last for about 2 years. If you want to have white teeth all the time, you can do cold light whitening every year or so.
