Teeth whitening tips
1. Cold light whitening
This is the only method that does not require polishing of teeth and relies on chemical whitening. You only need to go to the hospital once for the whole process, it only takes an hour, and your teeth can be whitened for at least three years. The price is quite good, and it can be done for about 1,000.
Applicable to: those who need to whiten their teeth temporarily (such as applying for a job, getting married) and have limited budget
Disadvantages: the duration is only three years. After three years, due to the re-mineralization of tooth enamel, The pigments in colored foods will slowly change back to their original color. Here, we also want to talk about whitening teeth strips. This is actually a by-product of cold light whitening. The principle is the same, but it takes effect slower. At first, it was used abroad as a maintenance effect after cold light whitening. Later, some manufacturers began to sell it separately. This is to say that whitening teeth strips can be used, but you must buy them from a regular manufacturer, follow the instructions, and do not use them too frequently. In addition, this whitening method is also very affordable.
2. Resin veneer whitening
It is to carve a shape on the outside of the tooth using resin to cover the original color. Because this method has high technical requirements for doctors, and if it is not done well, it can easily lead to a series of problems such as gingivitis and periodontitis, so it has been gradually phased out. Please don’t be fooled. This is what those beauty salons advertise as “6D non-grinding porcelain whitening”.
3. All-ceramic veneers
This is the longest lasting and most effective method. However, you need to grind your teeth, take a model, and then send it to an all-ceramic tooth manufacturer to make all-ceramic veneers. In fact, this kind of veneer sticks on very firmly and is basically impossible to remove, which means it can achieve permanent whitening. But the disadvantage is that it is very expensive and the cost is very high. The price of one tooth is 3,000.
