In general, the whitening effect can last for about 2-3 years after having our treatment. However, after several period of time, the whitening effect will subside and the color of the teeth will return to original one. As a result, we will also provide a series of home care products to our customers, so that they can have the self-treatment at home. We will tailor-make a professional dental protector for each customer. We suggest customers using our patented teeth whitening gel with the tailor-made dental protector after they brush their teeth at night. Every treatment will only last for 20 minutes. We also suggest our customer to keep this process for one week. Then, the sparkling white teeth will come back and can last for 1 year or more.
P.S. For those who always drink red wine, coffee or tea, we suggest customer having the regular treatment in our studio in order to keep the effect of sparkling white teeth.
