Many people want to try going to a dental clinic or dental whitening salon to find a professional dentist to whiten their teeth. But there will always be some concerns about how long a session of teeth whitening will last. Today, we answer this confusion for you.

Whitening Effect Duration

The effect of cold light whitening is not permanent, and the length of maintenance time varies with personal eating habits and tooth structure, but generally, it can be maintained for about two years. And within a day after the cold light whitening, you need to pay extra attention, because the teeth are easily stained at this time. ‍

Be careful after teeth whitening

1. Within 24 hours after the operation, in order to prevent the teeth from being stained with colored substances, do not drink tea, coffee, red wine, cola, berries and other beverages, do not consume colored toothpaste, mouthwash, etc., and eat dark foods. Also, avoid smoking.

2. You should also try to avoid dark foods in your usual diet, pay attention to oral hygiene, brush your teeth in the morning, noon and evening, and keep your mouth clean. Patients are advised to use whitening toothpaste, which can reduce the re-staining of food after cold light whitening.

3. Cold light whitening may have the side effect of causing tooth sensitivity to cold and heat, that is, it is particularly sensitive to stimuli such as cold, heat, acid, and sweetness, and it feels sour and tooth decay. It usually disappears on its own after a few days, or can be relieved with desensitizing toothpaste.

What you need to know before surgery

1. If you suffer from periodontal disease, gingivitis and other dental diseases, it is not suitable for teeth whitening. An X-ray examination is required before surgery to determine suitability. If there is a periodontal problem, it is necessary to treat the periodontal first, otherwise, it may cause the dental problem to worsen.

In addition, children under the age of 16, pregnant women, people who have had porcelain teeth, severe tetracycline teeth with enamel dysplasia, dental fluorosis, or patients with discolored teeth caused by other factors are not suitable for cold light whitening.

2. Some people may experience tooth sensitivity or toothache during the bleaching process. However, after the operation, the sensitivity or pain will gradually disappear, so you need to be mentally prepared.

3. Healthy teeth are not snow white. Do not bleach your teeth too white, otherwise, it will look unnatural. ‍
