Description

TOOTH WHITENING SYSTEM Related Applications

This application includes the use of novel compounds, the details of which are fully described in pending application Serial No. 08/863,419, the contents of which are herein specifically incorporated by reference.

Field of Invention

The invention applies to the field of dental care; more particularly to systems and devices designed to enhance the whiteness and reflective quality of human teeth.

Background of the Invention It has long been recognized that tooth color is a significant factor in facial appearance. The common perception is that a whiter or brighter tooth color enhances the effect of smiling and generally leads to a more attractive appearance. Periodic professional dental cleaning and polishing has been routinely used to enhance the

whiteness of teeth. This process, while effective, is far too costly and time consuming

to be used on a regular basis.

Other methods used to enhance tooth whiteness include replacing outer tooth

surfaces with crowns or veneers. While such procedures enhance tooth whiteness

substantially, they are extremely expensive and tend to be more prone to breakage than unsurfaced teeth. Teeth have also been bleached to improve whiteness.

Bleaching systems are provided by dentists and are available for home use as well. While bleaching systems are also effective, they involve the oral use of strong

chemicals which may have toxic side effects.

What is needed is a tooth whitening system which is safe, effective, convenient and low cost. To date, none of the prior art inventions have achieved all of these objectives.

Summary of the Invention

The present invention addresses all of the desired features for a tooth whitening system identified as lacking in any single invention of the prior art. The invention adapts some of the mechanical technology long employed by dentists to provide safe and effective tooth whitening. At the same time the invention avoids the use of strong chemicals while providing an easy to use, low cost system which can be used in any convenient location.

The present invention includes a novel tooth whitening elongated member and

methods for using the tooth whitening elongated member and other apparatus and

compounds. The tooth whitening elongated member can be constructed from five

components. These components include a frangible, hermetically sealed container, a tooth whitening solution disposed within the container and a flexible vial having an

open first end and a closed second end. The frangible container is located inside of

the vial which has wicking applicator material in the open first end of the vial and extending axially out of the vial. When the vial is held with the applicator material

positioned below the closed end of the vial and the vial is squeezed to rupture the container the solution flows into the applicator material in the first end of the vial and

the applicator material may be applied to a person's teeth to whiten them.

In a variant of the invention a safety sleeve is provided having an open first end and a closed second end is sized to fit closely and slidably over the vial. When the first end of the vial is removably placed in the sleeve in a first position the applicator

material is adjacent the closed second end of the sleeve. When the vial is placed in the safety sleeve in a second position the applicator material and the open first end extend

axially outward from the safety sleeve, thereby further protecting a person's fingers

while rupturing the container. In another variant of the present invention the frangible, hermetically closed container is in the form of a glass ampoule. In yet another variant, the vial is in the form of a flexible tube with an open first end and a closed second end. In yet another

variant the tooth whitening solution comprises a solution of colostrum, hydrogen peroxide, water with stabilized oxygen, flavoring, sodium saccharin and Poloxmer

407.

The method for whitening teeth includes the use of the tooth whitening elongated member as described above and a series of other steps. First, the tooth

whitening elongated member is positioned so that the applicator material extends

below the closed second end of the vial and sufficient pressure is applied to the vial so that the frangible container is broken and the whitening solution is released and flows

downward into the applicator material. After waiting until the whitening solution to saturate the applicator material the applicator material is rubbed on the teeth to apply the whitening solution to them. Next the teeth are rinsed and the polishing phase of the method is begun.

In a variant of the invention the teeth are rinsed with a solution comprising hydrogen peroxide; water; polysorbate 20; xylitol; flaror; acesulfame K; polaxamer

407; sodium benzoate; potassium sorbitol; PPG26 Buteth 26/Peg 40; hydrogenated castorn oil; stabilized oxygen; and colostrum.

In another variant of the invention the tooth whitening elongated member is provided with the vial placed in the safety sleeve in a first position. Next, the sleeve is removed from the vial and the vial squeezed to rupture the container. In another variant of the method of the present invention the vial is placed into the sleeve in a second position so that the applicator material and the open first end of the vial extend axially outward from the safety sleeve so that the fingers of the user are further

protected when the container is ruptured..

A polishing machine is provided which includes a mandrel; a means of

providing torque to the mandrel; a power supply for the means; a handle for

positioning the mandrel; and a switch for controlling the means. A deformable

polishing tip frictionally fitted to the mandrel is provided along with tooth polishing

compound. The polishing compound is applied to the polishing tip. The polishing tip is applied to teeth while closing the switch and moving the polishing tip back and

forth gently over teeth. Polishing compound is reapplied to the polishing tip as

required. Next the teeth are rinsed.

As maintenance for the polishing machine and polishing tip, the polishing tip is

next removed from the polishing machine and the polishing tip is washed with water. The mandrel of the polishing machine is then dried and the polishing tip is replaced on the mandrel.

As a variant on the method of the present invention the tooth polishing compound may be provided in individual application packages. These individual

packages are broken open and squeezed to eject the polishing compound.

As a further variant, the method may be practiced by providing a polishing compound comprising water; sodium lauryl sulfate; pumice; Carbomer Ultra; Polysorbate 20; T.E.A.; sodium saccharin; flavoring; sodium benzoate; calcium

disodium EDTA; stabilized oxygen; and colostrum.

STATEMENT UNDER ARTICLE 19
Claims 1 and 2 have been combined into amended claim 1. This combination adds the element of a safety sleeve to the elongated flexible vial of the tooth whitening elongated member. Thus the present invention may be distinguished over the disposable applicator for nail polish or other liquid disclosed in Chernack (PCT/US84/00363) and cited by the Authorized Officer as relevant to claims 1, 2, 4, 5 and 7. Likewise, claims 7 and 9 have been combined into amended claim 7 to include the method of utilizing the safety sleeve with the tooth whitening elongated member. As claims 4 and 5 now depend from amended claim 1, the Authorized Officer's assertion of relevance should now be obviated.
As Wagner (U.S. Patent No. 5,611,687) cited by the Authorized Officer as relevant to claims 1, 2, 4, 5 and 7 includes "means for drawing the oral hygiene preparation to the applicator tip by capillary action." (claim 1, lines 44-46), and as this element is missing from the present invention, Applicant feels that no amendment is necessary to avoid Wagner.
