A: All whitening products may cause tooth sensitivity and/or gum discomfort during use. For products with strong whitening effects, this possibility will be greater. The sensitivity and discomfort are usually mild, temporary, and not harmful to the teeth. If obvious tooth sensitivity or gum discomfort occurs and tends to worsen, you can suspend use for two or three days before continuing. If the situation does not improve, you can stop using it. Q: Is this product safe? A: The professional whitening ingredients selected are safe and will not damage tooth enamel. Q: Sometimes I find small white spots/white lines on my teeth after removing the dental strips. Will this disappear? A: This is normal. Some white spots/white lines are caused by the whitening effect of dental strips. Such white spots/white lines are temporary and will disappear after a while. There are also cases where whitening makes existing tooth imperfections more visible, which may also appear as white spots/lines on the teeth. Q: Should I use it before or after brushing my teeth? A: It can be used before or after brushing your teeth. To avoid possible discomfort, it is recommended to use it before brushing your teeth, or use it half an hour after brushing your teeth. The whitening effect will be the same in both situations.
