Philips InterCare Sonic
Standard brush heads

Cleaning of interdental spaces and hard-to-reach places
With innovative sonic technology and extra-long bristles, the Philips InterCare Sonic brush heads remove as much as 7x more plaque than a regular manual brush to improve gum health in just two weeks. The reminder bristles and Sonicare technology will let you know when it is time to replace your brush head, so you will always be cleaning effectively.
