1. An oral hygiene implement comprising:
- a head portion sized for insertion into a human mouth, the head portion comprising;
a base; and
a plurality of elastomeric elements extending from the base, each elastomeric element defining one or more edges, wherein a total number of edges defined by the plurality of elastomeric elements having a tip radius of less than about 0.006 inch is greater than about 250.

Abstract
Oral hygiene implements, such as manual or electric toothbrushes or refills, include a head portion sized for insertion into a human mouth that includes a base and a plurality of elastomeric elements extending from the base to define a field of elastomeric bristles. The field can include a first elastomeric element that includes a first elastomeric material and a second elastomeric element different than the first elastomeric element that includes a second elastomeric material. The elastomeric elements extending from the base can define many “sharp,” yet compliant edges, such as those having a tip radius of less than about 0.006 inch, for enhanced cleaning with reduced abrasion.
