A whitening pen can generally be used 8 to 10 times.

At the beginning of the treatment, it is recommended to use it continuously for 7 days, and then it is also recommended to use it every day; or once the target effect has been achieved, use it once a week.

It depends on the tooth quality of each person. Generally, you can see the obvious whitening effect after one week of continuous use according to the instructions, and you can complete your smile improvement project in two weeks.

The effect can be maintained for more than 12 months. Of course, the length of the effect will be affected by your habits of smoking, drinking coffee, strong tea, aerobic drinks, red wine, and eating foods with heavy pigments. If you have the above habit, it is recommended to use it regularly to maintain the whitening effect.

You need to brush your teeth before and after use. After use, you can directly use the toothbrush to brush the surface of the teeth. Each use is about 20 minutes, not more than 30 minutes.

It is recommended to twist the whitening pen to apply at least two teeth at a time, and the whitening liquid can cover the surface of the teeth.

Don't twist it vigorously, otherwise too much whitening fluid will flow out. Don't be anxious the first time you use it, because the brush will take time to absorb the whitening solution. After use, please wipe off the pen with a clean paper towel.

There are no special rules. It is recommended to use it 1 hour before going to bed to rest your teeth after use; or use it every day before going out.

It is recommended not to eat or drink for 1 hour after use, and not to drink coffee, milk tea, chocolate, Chinese medicine, Chinese strong tea, cola and other heavy-pigmented beverages within 4 hours
