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.

A: 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

Our whitening pen is provided by Dr. Fresh, one of the largest oral product suppliers in the United States, and is made in the United States. The ingredients include Purified Water, SDA 38B, Polyvinyl Pyrrolidone, Polyethylene Glycol, Hydrogen Peroxide (6%)

Hydrogen Peroxide can play a redox effect and remove the deep pigment of the teeth. The higher the concentration, the stronger the stimulation. Peroxide is also an ingredient often used by dentists for whitening teeth. The use of Hydrogen Peroxide for teeth whitening has a long history, and many tests have proven its safety.

Easywhite美白筆的HP濃度是6%。很多牙醫診所使用高濃度Hydrogen Peroxide，他們有安全的設備及專業知識，保護你的安全。根據牙醫建議，家用牙齒美白產品所含的PH濃度不宜太高(8%或以上)，使用不當，會容易造成牙肉﹑牙齦甚至嘴唇敏感發痰。

The whitening pen has a scent similar to mint, and there will be a slight coolness or numbness when using it. If this feels strong, stop using it immediately and rinse your mouth with warm water. In case of strong tooth sensitivity, please stop using it for 24 to 48 hours. If this happens again, please disable it permanently.
