The system periodically measures the battery voltage of the toothbrush and the current in a stator portion of the motor for the appliance. The amplitude of movement of the toothbrush workpiece is determined from the measured stator current. A circuit / control program changes the duty cycle or pulse width of the drive signal from the motor if the battery voltage drops below a first threshold value and a circuit or control program changes the drive frequency of the appliance if the amplitude of the workpiece movement falls below a first threshold value. A circuit / control program terminates the operation of the toothbrush if the voltage drops below a second threshold value or if the amplitude drops below a second threshold value, both of which are less than the respective first thresholds.

The toothbrush of the present invention comprises an elongated handle having a head attached to one end. The head has a bristle-bearing face having longitudinal perimeter portions adjacent longitudinal edges and at least two perimetric, elastomeric massaging elements alternately arranged with groups of bristle tufts along each of the longitudinal perimeter portions. The brush can comprise further massaging elements which are not located along the longitudinal perimeter portions though the use of such additional elements is preferably minimised. The perimetric massaging elements have rotational symmetry through an angle of 120° or less, preferably being circular. The cross-sectional area proportion of elastomeric massaging elements to bristles on the brush head is less than 25%. Alternately there are four or fewer elastomeric massaging elements which are not perimetric massaging elements. A brush with both bristles and gum massaging elements arranged as set out above provides both cleaning and gum massaging benefits without creating an undesirable aesthetic impression derived from the use of rubber-like materials in the part of the brush head traditionally comprising only bristles.

An electric toothbrush is provided. The electric toothbrush has an elongated body, a head, and a neck extending between the body and the head. A plurality of bristle carriers each having a plurality of bristle tufts are disposed on the head. An electric motor is operatively connected to a shaft, wherein operation of the electric motor moves the shaft in a reciprocating motion and wherein the shaft is operatively connected to at least one of the bristle carriers to move the bristle carriers.

An electric toothbrush comprising an elongated body portion and a head including a static portion and a moving portion, a handle, and an angled shaft between the head and the handle. The portion of the toothbrush containing the head is detachably connected to the portion of the toothbrush containing the handle.

A cleaning and whitening system for teeth having an electromagnetic radiation emitting toothbrush and a dentifrice with a photosensitive agent is disclosed. The toothbrush has a cleaning surface, such as bristles. The toothbrush is also adapted to direct electromagnetic radiation toward the cleaning surface. The electromagnetic radiation may be monochromatic or polychromatic. Further, the electromagnetic radiation may be substantially free of ultraviolet radiation. Additionally, the electromagnetic radiation may consist essentially of wavelengths within a range of 300 to 750 nanometers. The photosensitive agent is dispersed throughout the dentifrice. The dentifrice transmits the electromagnetic radiation through a varying thickness disposed over a target surface during use of the system. As a result, a significant portion of the photosensitive agent reacts, resulting in whitening stains, removing and / or disclosing undesired substances, and / or foaming. The dentifrice may be clear and may have clear abrasive particles. A method for tuning the cleaning and whitening system for teeth includes formulating the dentifrice with photosensitive agents that react to a range of electromagnetic radiation and providing a toothbrush that emits that electromagnetic radiation range. Another method of tuning the cleaning and whitening system includes designing a toothbrush that emits a range of electromagnetic radiation and formulating a dentifrice with photosensitive agents that react to the electromagnetic radiation range.

This invention relates to a toothbrush that utilizes a replaceable brush head having rubber gum guard on its top surface and a triangular shaped rubber pad on its bottom surface. The rubber gum guard is shorter than the height of the bristles and is positioned on the peripheral edge of a brush head for functioning as a sensor for providing feedback to prevent brushing at excessive pressures and improper angles as well as for massaging the gumlines without the risk of gum damages. The triangular shaped rubber pad is for conforming to and massaging gumlines at the back of teeth. The replaceable brush head having the rubber gum guard and massaging pad features is economically used in conjunction with a permanent handle that dispenses dentifrice material to the top of bristles. The handle has a resilient contractible connector for secure mounting of the replaceable brush head.

A multiplicity of bristles extend from the heel region of the head; the distal ends of these bristles form a longitudinally aligned concave shape when viewed on end. Likewise, a multiplicity of bristles extend from the toe region of the head, wherein said bristles extending from the toe portion of the head are at least as tall as the general height of said bristles extending from the heel portion when viewed from the side and wherein the side profile view of the distal ends of the bristles extending from the toe portion form a generally linear surface which forms an angle relative to the general plane of the bristles extending from the heel portion of from 0 DEG to about 45 DEG declining from the edge of the toe portion distal to the heel portion to the edge of the toe portion which is proximal to the heel portion.

A toothbrush is provided for cleaning and / or massaging of teeth and gums having a mechanical vibratory element and a head having cleaning / treating elements on a plurality of different types of cleaning areas which provide for an enhanced cleaning, scrubbing and massaging effect. The cleaning / treating elements have different physical characteristics so that in addition to providing a varied cleaning / treating effect from the cleaning / treating elements themselves there is enhanced treatment as a result of the movement of the cleaning / treating elements imparted by the mechanical vibratory device.

An motorized electric toothbrush (10) includes a removable brush head (16) and a switch (12) that allows the toothbrush (10) to be used in an “automatic” mode. The “automatic” mode provides for intermittent motorized operation, such that when the brush head (16) contacts the operator's teeth, a second switch (20) is automatically actuated and the motor (14) engaged. The brush head (16) is easily removed for replacement when the bristles become worn or allow use of the toothbrush (10) by multiple users.

A toothbrush includes a head and a tooth cleaning element extending from a top surface of the head. The head is divided into at least two portions which can be moved independent of each other.

A brush having antimicrobial characteristics that inhibit bacterial growth. The antimicrobial agents, compounds or chemicals are embedded in either the body or bristles or both of the brush. Further, the present invention is a method of manufacturing a brush having antimicrobial characteristics that inhibit bacterial growth. An antimicrobial additive is incorporated in resin concentrate form into the amorphous zones of the molecular structure of the polymer from which brush handles are injection molded, thereby incorporating the antimicrobial agent into the brush handle. The antimicrobial additive in the body of the brush, incorporated in the manner above, results in substantive controlled migration from the body to the bristles, until a point of equilibrium is reached. The invention is suitable for any brush in which bristles are embedded in plastic, including toothbrushes, hair brushes, scrub brushes, toilet bowl brushes, cosmetic brushes, lip-color brushes, etc.
