It Works for Me So Far!

I have tetracycline-stained teeth due to medication I had when I was young. I have been searching for a solution without damage my teeth. I am so glad to find Kor whitening. I started the treatment at the beginning of May 2023. It works for me so well so far. I strongly recommend anyone who had similar situation to try it. I attached the pictures before and after. Of course, it is not perfect white but I am already very happy with the results.
