I absolutely love coffee, and over the years of drinking it daily, my once-white teeth mysteriously developed a grayish tint. So I tried all sorts of professional teeth whitening treatments. I've experimented with many methods (yes, I know people say gray teeth can't be whitened, but I guess I'm the exception). After countless attempts, I finally found these whitening strips. You can use them for a full week, and since then, I've used whitening strips every year to maintain my bright smile. It turns out that high-quality whitening strips (like these 9D Professional Effect strips) genuinely do whiten teeth. The two intensive whitening strips in the kit kickstart the process quickly. My results were outstanding and remained strong even six weeks after completing the treatment. Detailed Notes: My teeth are somewhat sensitive, but if discomfort occurs, I gently brush or pause use for a day. (If your teeth tolerate it, using once in the morning and once at night yields more noticeable results.) Use whitening toothpaste in the morning and a mild toothpaste at night. Avoid mouthwash during the treatment period. Beyond my morning coffee, I steer clear of foods and drinks that stain teeth. I suggest doing some research, as many seemingly harmless items—like certain clear sodas—can actually cause discoloration. Even some toothpastes can stain teeth—you might even find warnings on mainstream brand packaging! After eating or drinking in the morning, wait 30 minutes before flossing and brushing. Then wait another 30-40 minutes before applying the whitening strips. After finishing one box of whitening strips, I return to my regular routine: Colgate Whitening Mouthwash and matching whitening toothpaste in the morning, and mild toothpaste at night. Based on personal experience, the mouthwash itself has limited whitening effect but is highly effective at maintaining tooth whiteness. Be sure to follow the instructions: avoid eating or drinking for 30 minutes after rinsing for 1 minute. If consuming staining foods, rinse with water after using the mouthwash. Consistently brushing twice daily is truly key for me. You can speak normally while using it, which is very convenient. Translated with DeepL.com (free version) Read more
