How long does cold light teeth whitening last?

Cold light teeth whitening is a common method of teeth whitening and the technology is relatively new. Generally speaking, after such treatment, the teeth whitening can be maintained for about two years. Of course, this is related to the personal lifestyle. If you pay more attention to oral hygiene, the teeth whitening time will be longer. Before cold light whitening, if there is periodontal disease, it should be treated first.

How long does cold light teeth whitening last?

Everyone wants to have white and beautiful teeth. It is understood that cold light teeth whitening is a safe and effective method of whitening teeth. So, how long can the effect of cold light teeth whitening last?

From the moment we were born into this world, our teeth have been spotlessly white. After many years, the dental tubules will change color and have material deposits. Although teeth whitening relies on the redox principle of cold light whitening, pigment deposition will still occur in life. Therefore, cold light whitening is not a one-time solution. How long does the cold light teeth whitening effect last?

Theoretically, the effect of cold light whitening can generally last for about two years. We have been doing cold light whitening since 2003. Through follow-up investigations, we found that some people maintained the results for about two years, and some are still in good condition. It seems that how long the cold light teeth whitening effect can last varies with individual eating habits and tooth structure.

Cold light whitening is more effective for mild to moderate tetracycline teeth and fluorosis teeth, and can improve the color of severely stained teeth. Mildly colored teeth can be whitened once with cold light. Moderately colored teeth can be whitened a second time one month after the first cold light whitening. Experts say that for teeth that have not undergone any whitening treatment before, the effect of cold light whitening will be better and longer lasting.

Finally, I would like to remind everyone that teeth can easily be stained with colored substances within 24 hours after cold light whitening. Therefore, you should not drink colored beverages such as tea, coffee, cola, red wine, dark foods such as soy sauce, and do not smoke after cold light whitening. 24 hours later everything returned to normal.

Preparation before cold light teeth whitening

1. If you have dental problems such as periodontitis and gum disease, teeth bleaching is not suitable. It is recommended to have an X-ray to determine whether teeth bleaching is suitable. If there are periodontal problems, the teeth need to be repaired first and then bleached. Otherwise, it may lead to worsening of dental problems.

2. Consult a dentist first. Not everyone is suitable for teeth bleaching. Sometimes, unsuccessful tooth bleaching can result in uneven tooth color. Tooth bleaching is best for people who wear dentures.

3. Teeth bleaching may have side effects. Some people may experience tooth sensitivity or toothache during the bleaching process. But after the operation, the sensitivity or pain will gradually disappear.

4. Healthy teeth are not snow-white. Do not bleach your teeth too white as this will look unnatural.

In addition, the following health care methods are required after cold light whitening:

1. Use whitening toothpaste in combination with fluoride toothpaste to whiten and strengthen the skin at the same time.

2. Maintain good oral hygiene habits and brush your teeth on time every morning and evening.
