Kolibree, a smart toothbrush

The Kolibree toothbrush is suitable for adults and children, and is particularly useful for teaching them how to brush their teeth properly, regularly and without missing any areas. The toothbrush provides plenty of useful information: duration of brushing, whether you are brushing too vigorously, etc. The company’s studies have shown that Kolibree reduces plaque by 50% in children, compared with a “normal” toothbrush.
