I had always been very concerned about my tooth color, but before the procedure, the director explained my current tooth condition and color in great detail and with great kindness. Thanks to that, the consultation went well to find the perfect tone for me, and I am very satisfied with the result, as it turned out naturally brighter without looking too artificial. I was worried that my teeth might be very sensitive after whitening, but I felt almost no sensitivity at all, so it was comfortable. However, I felt a slight sting in my gums after the procedure, which surprised me a bit since I have never had any gum disease. When I asked the director, they explained that this can happen temporarily during the whitening process. Fortunately, my gums felt better after a few days. I am satisfied because the color turned out perfectly—just beautiful, without being excessive.
