The same white color will increase the charm of the whole person, but there are also many people who have yellow and black phenomenon due to different reasons. There are also many clinical solutions, such as cold whitening teeth, but many people do not understand the cost of cold whitening teeth. Then, let's take a look at the price and principle of cold light tooth whitening.
1、 How much is cold light tooth whitening? Price Reference
How much is cold light tooth whitening? The cost of cold light tooth whitening is generally about 10000~4000 yuan, and the specific price is related to the selected hospital doctors, equipment and patients' personal teeth.
1. Doctors of the selected hospital

First of all, it is related to the hospital doctors selected by everyone, because there are many hospitals of different levels in the market, and there are certain differences in fees. For example, for high-level hospitals, the power facilities of the hospital will be relatively complete, the entire medical environment will be relatively comfortable, and the doctors in the hospital have relatively good skills, so the price of cold light teeth whitening will be higher.
2. Related equipment
At present, there are many production categories and product manufacturers of cold light whitening therapeutic devices, so different medical devices and equipment determine the charging standard, so the cost will vary with the equipment we choose in the treatment process.

3. Individual tooth condition of the patient
Because each person's tooth condition is different, cold light tooth whitening mainly has a good therapeutic effect on teeth dyed with exogenous pigments. Therefore, in the treatment process, if the tooth color depth is different or the dyeing time is different, the treatment process will be affected, so the cost will also be related to individual teeth.
What is the principle of cold light tooth whitening?
Cold light tooth whitening is mainly used to illuminate the tooth surface through a high-intensity blue light source during the treatment process. The tooth surface is coated with a special whitening agent. After irradiation, the whitening agent will gradually penetrate into the tooth surface and deep layer. After a long time of operation, the teeth will become white and the color will change.

This method is safe in clinic, and whitening is also a common tooth whitening method. After treatment, corresponding tooth care should be done.
How long can cold light whitening teeth last?
Generally speaking, cold light whitening teeth can be maintained for about 1~2 years, depending on personal conditions. First of all, the maintenance time will also be affected due to different hospitals, equipment and materials selected by everyone.

Secondly, everyone's postoperative care is different. Some people pay more attention to postoperative care, so the maintenance time will be relatively prolonged. In short, if you want to keep cool and whiten your teeth for a long time, you should strictly follow the doctor's advice.
4、 What precautions do you have after cold light tooth whitening?
The teeth will be more sensitive after treatment. At this time, you should not drink too hot or cold food, or drink drinks with heavy pigments, such as coffee, tea, or cola. You should also pay special attention to not smoking or drinking.
