Sonic brush head comes off the wand while brushingUpdated 2 years ago

Our sonic brush heads are made of all-natural ingredients, including cornstarch inside the head. Wetness and moisture can cause the cornstarch filling to become soft. Allow it to fully dry, and please be careful not to get the inside of the brush head wet.

Sometimes the vibration causes the cornstarch to "heat up" and melt with use- especially if you brush with closed lips. We recommend brushing the lips open and not coming in contact with the brush head, reducing friction on the lips and inside the brush head.
