According to the dentist recommendation, the brush head should be replaced every 2 or 3 months. For the electric toothbrush which has color reminder bristles, you don’t need to track the time physically. Change the head when the blue reminder bristles totally fade away and turn into fair white.

It takes 2 hours for a fast full charge and will last 30 days or more.

Yes, P11 is fully washable. The P11 is IPX7 waterproof, which can be rinsed under the faucet. But please DO NOT soak it in the water.

Please charge your toothbrush. The first charge time should be longer, preferably 5 hours.

Please contact us at if the indicator is still not on after full charge. 

All Fairywill electric toothbrush comes with a USB charging cable. So the power bank or adapter with USB port (within 5 V/600 mA) is able to charge Fairywill toothbrush.

Detach: Twist toothbrush head counterclockwise for 15 degree. Pull it out along the handle.

Install: Slide the toothbrush head down to the handle. Twist it clockwise.

We do not recommend disinfect the handle with alcohol. Since the handle is painted, the alcohol can make the paint on surface fall off.

Generally a small amount of water will not affect charging. But when there’s water at charging port, it is best to simply wipe off and drive the device thoroughly before charging.

People with severe periodontosis or oral surgery should ask your dentist before using.

It isn’t a must to replace your brush head after getting sick. According to CDC, the flu virus can only live on moist surface for 72 hours. The risk of getting sick again is very low as long as your immune system is not severely affected.

To avoid gum irritation, please DON’T brush immediately before or after using the Whitestrips. Plus, since the whitening agent takes time to take effect, please wait at least 30 mins to brush after using the whitestrips. And rinse your mouth only with water after using the whitening strips.

Don’t worry. White spots are normal and will go away soon.

White spots are the result of water loss on the surface of teeth caused by uneven enamel density. The white spots are noticeable where the enamel density is thin. These dry thin areas absorb the light and appear as white spots. As soon as the enamel is hydrated again, the white spots will vanish.

To avoid affecting the dental treatment results, please do not use the whitestrips when you are having crowns, caps, fillings, veneers, partials, gold, laminates, composite bonding, or other dental restorations.

Normally, Fairywill Whitening Lights won’t cause teeth sensitivity issues. However, using too much gel can irritate and affect your teeth. Therefore, please use the indicated amount of gel.

Please immediately stop it and wash your mouth with cool water or brush teeth if it causes pain or teeth sensitivity issues.

For better whitening result, we recommend not to drink coffee, tea, wine or carbonated drinks. Plus, try not to eat strongly color fruits such as cherries, strawberries, blueberries, etc.

Please wait at least 30-60 minutes before eating or drinking coffee/soda. But you can drink water at anytime.

First, dental crowns are made from materials that cannot be whitened, such as metals alloys and ceramics. Second, applying the strips over the crown can affect the gum line and the pillars. Last, the natural teeth get whiter while the artificial crowns will remain their original color, causing color discrepancy.

Please avoid touching your gums when using the strips. Because touching gums with strips or any other objects may induce bleeding, ulcers, and infections. Please place the strips carefully above the gum line when using them.

After peeling off the strips, you need to attach the sticky side to your teeth.

Shorter strips for your lower teeth and longer for the upper teeth. Make sure do not apply on your gum area. Remove the whitestrips after at least 30 minutes.

Fairywill teeth whitening strips are used once a day, and we recommend that use them at night before going to bed.

Since each person's whitening degree of teeth is different before using teeth whitestrips, people who regularly drink tea and coffee will have a noticeable whitening effect after using strips. However, some people originally have white teeth and want to whiten their teeth more. This time, one or two times of use may not be so fast to find a rapid whitening effect.

So we recommend that use a complete box to two boxes of whitening strips. After finishing complete treatment, you will see the whitening effect and maintain whitening effect.

It’s not a permanent treatment. The whitening result lasts from 1 - 3 months. Depends on your diet and how you take care of your teeth. People who brush daily and avoid staining foods and beverages (coffee, wine, tea, tomato sauce, etc) can enjoy longer whitening effect.

We recommend not to use Whitestrips when pregnant or nursing. Although there is no specific evidence regarding any negative effects to mother or baby. It’s best to avoid any risk that could be caused by the active ingredients in the product.

Please don’t worry about it. Excessive salivation is a natural reactive response when new elements and objects enter your mouth. Therefore, you might notice some increase salivation the first time you use them.

Also, it’s common to experience a foam produced by the combination between the whitening agent and saliva.

People under 18 ages are not recommended to use the whitening strips. Because primary teeth in those ages are not as sturdy and resistant as permanent teeth.

The Fairywill whitestrips contain peroxide ingredients, which can release active oxygen to decompose the colored substance on the teeth.
