Abstract
A teeth cleaning system, which provides improved coverage or brushing area. The system includes an actuated tray comprises brushing elements. The brushing elements may be positioned to engage the front, rear, and top surfaces of the upper and lower jaw teeth. The actuation may be configured to oscillate the tray in a lateral direction which may brush all the surfaces of teeth simultaneously. Some embodiments include a higher density of bristles which increases the effectiveness of brushing. In addition, aspects of the system reduce the time spent brushing teeth.
Claims20
A teeth cleaning system, comprising:
- an arcuate tray configured to receive a set of teeth, wherein the arcuate tray includes:
- an inner arcuate wall,
- an outer arcuate wall,
- a baffle positioned transversely across between an inner surface of the outer arcuate wall and an inner surface of the inner arcuate wall and defining an upper channel for receiving teeth of an upper jaw and defining a lower channel for receiving teeth of a lower jaw, and
- a plurality of bristles positioned in the upper channel and in the lower channel;
- a connector that is coupled to an outer surface of the outer arcuate wall of the arcuate tray, wherein the connector has an inner surface that defines a cavity and a mating element that is positioned within the cavity;
- and
- a handle that includes:
- a shaft that is covered by a sleeve, wherein the sleeve is detachably receivable within the cavity defined by the inner surface of the connector and the shaft is detachably receivable by the mating element of the connector;
- a motor, and
- an oscillator configured to move the arcuate tray side-to-side along a same plane as the baffle by moving the shaft side-to-side in response to operation of the motor.

A teeth cleaning system, comprising:
- an arcuate tray configured to receive a set of teeth, wherein the arcuate tray includes:
- an inner arcuate wall,
- an outer arcuate wall,
- baffle positioned transversely across between an inner surface of the outer arcuate wall and an inner surface of the inner arcuate wall and defining an upper channel for receiving teeth of an upper jaw and defining a lower channel for receiving teeth of a lower jaw, and
- a plurality of bristles positioned in the upper channel and in the lower channel, wherein the plurality of bristles comprises a density of between 324 bristles per cm2-646 bristles per cm2;
