The Intercare brush head is Philips Sonicare's best interdental brush head. Compatible with all click-on Sonicare models, these replacement brush heads have three tufts of specially designed bristles to provide a deep clean between teeth and improve gum health in just 2 weeks. Intercare's anchor-free tufting technology allows for unique bristle patterns and lengths to achieve clinical superiority, removing up to 7x more plaque between teeth than a manual toothbrush and reaching 35% deeper between teeth than the Oral-B Floss Action brush head.
