As I regularly enjoy drinking coffee and tea, seeing my teeth turn yellow every time I looked in the mirror was a major source of stress. I felt self-conscious whenever I smiled or spoke, so I finally mustered the courage to schedule a dental whitening appointment. Before my visit, I was very worried that my teeth might be sensitive or painful during the procedure, but fortunately, the medical staff meticulously applied a gum protectant and carefully checked my condition periodically, allowing me to receive care very comfortably. There was almost no pain, much less than I expected, to the point where I even dozed off for a moment. The moment I checked the mirror after the procedure, I was truly surprised to see that my teeth looked much more transparent and brighter than I had expected. My overall impression feels cleaner, so I feel more confident and find myself smiling naturally every time I look in the mirror. As advised by the dentist, I plan to avoid foods with strong pigments like curry and coffee for the time being to maintain my white teeth for a long time. If you are considering teeth whitening, I highly recommend getting it done as soon as possible without wasting any time! It was a choice I have no regrets about.
