ABSTRACT:
A toothbrush that provides enhanced cleaning and oral care to a user. The toothbrush has a head with cleaning elements that create a contoured cleaning profile. The cleaning elements have different depths of insertion relative to a reference plane to define a contoured cleaning profile without post-fixing trimming of the cleaning elements. Accordingly, tapered bristles can be used to define a contoured cleaning profile. Alternatively, tapered bristles of different lengths can also be used to form a contoured cleaning profile.
