Abstract
Oral devices are provided, including oral brushes that include bristle tufts and a rotatable member having radially extending tips constructed to penetrate the interproximal and subgingival regions of the oral cavity.
Claims35
A oral brush comprising
- a body having a head that is shaped for insertion into the oral cavity,
- tooth cleansing elements extending from a top surface of the head, and
- a rotatable element, mounted on the head to rotate about an axis of rotation, including a central portion ad a plurality of tapered members extending radially from the central portion, each tapered member comprising a unitary body tapering from a relatively wide base to a relatively narrow tip, the tip defining linear surfaces that are generally parallel to each other and defining a distal edge that is generally parallel to the axis of rotation, the tip being constructed to penetrate the interproximal region.
An oral brush comprising
- a body having a head that is shaped for insertion into the oral cavity,
- tooth cleansing elements extending from a top surface of the head, and
- a rotatable element, mounted on the head to rotate about an axis of rotation, including a central portion and a plurality of tapered members extending radially from the central portion, the tapered members comprised of unitary bodies including tips, each tip defining linear surfaces that are generally parallel to each other and defining a distal edge that is generally parallel to the axis of rotation, and having a tip thickness at the distal edge of less than 0.03 inch.
An oral care device that includes a body having a head shaped for insertion into the oral cavity, and a rotatable element mounted on the head to rotate about an axis of rotation, including a central portion and a plurality of tapered members extending radially from the central portion, each tapered member comprising a unitary body tapering from a relatively wide base to a relatively narrow tip, the tip defining linear surfaces that are generally parallel to each other and defining a distal edge that is generally parallel to the axis of rotation, the tip being constructed to penetrate the interproximal region.
An oral brush comprising
- a body having a head that is shaped for insertion into the oral cavity,
- tooth cleansing elements extending from a top surface of the head, and
- a rotatable element, mounted on the head to rotate about an axis of rotation, the rotatable element including a central portion and a plurality of tapered members extending radially from the central portion, each tapered member tapering from a relatively wide base to a relatively narrow tip and being integrally formed of an elastomeric material, and each tip defining a distal edge that is generally parallel to the axis of rotation, and having a tip thickness at the distal edge of less than 0.07 inch.
