Abstract
Abstract The device has an elastic cleaning head with an aperture. On the inside facing the aperture there is a brushless cleaning layer (12), e.g. of looped fabric. For cleaning purposes the head is first fitted over an incisor (15) and moved to and fro, fully covering the teeth (15, 16) on three sides. The device is simple and economical to make and fully cleans the teeth without damaging the tooth surface.
