Abstract
There is provided a toothbrush comprising a handle and a hollow head supporting a plurality of tufts, each tuft consisting of a bundle of bristles fixedly joined together at one end. The head further comprises an elastically deformable element which, in the state of rest of the toothbrush, urges the tufts towards a limit position. When pressure is applied to at least one tuft during the use of the toothbrush, it causes the collective tips of the tufts to conform to the contours of a given group of teeth as a result of the tufts being pushed into the hollow head to varying degrees against the restoring force of the elastically deformable element.
