Willo's main purpose is "toothbrushing" and is not meant for flossing. While the fluid movements during a cycle help, we are still studying the efficacy of Willo in plaque removal in between the teeth, so in the meanwhile, we recommend you keep flossing with string floss or interdental brushes.

Specially formulated Rinse Pods act as the toothpaste agent while brushing with Willo, and last 45 days if you brush twice daily with the basic cycle. You’ll receive 2 new Rinse Pods for each user, every 3 months.

Like a regular brush head, you should replace your mouthpiece every 3 months. With Willo's Refills subscription, you don't have to remember to replace your mouthpiece - we will automatically send you a new mouthpiece every 3 months with 2 rinse pods (aka toothpaste) directly at your door.

You should not rinse your mouth with water after you brush with Willo and actually, after any toothbrushing device. Rinsing your mouth with water after brushing removes most of the active ingredients delivered and will decrease their efficacy. If you want to rinse your mouth, we advise you to use fluoride rinse after your toothbrushing routine.

With your device, you will have a choice between 5 different NFC Willo rings that will help you distinguish your mouthpiece from the other. The Willo ring can also be linked to your very own profile on the Willo mobile app so you can access data on your brushing and change your brushing cycle.
