Dentifrice is generally known as a paste, gel, liquid, or powder for cleaning teeth. Dentifrice is currently available in many different types and brands with various compositions to address different teeth cleaning needs, including food debris removal, plaque removal, teeth whitening, preventing tooth decay, and decreasing tooth sensitivity. While the composition of dentifrice plays an important role in teeth cleaning, proper brushing and rinsing techniques are paramount to preventing tooth decay and cavity formation. Proper brushing techniques should be taught in the early stages of life (i.e. childhood) to instill good brushing habits to maintain oral hygiene. Likewise, proper rinsing techniques should also be taught as rinsing exposes the teeth to fluoride and removes toxins from the mouth that may otherwise be harmful if ingested. However, it is estimated that 60% of the United States population does not know how to teach their children proper brushing and rinsing techniques nor do the parents know the causes of cavities or the caries process. In addition, the parents may have a difficult time educating their children about the caries process, bacteria accumulation, and cavity formation associated with poor brushing and rinsing techniques.
One primary teaching point to a proper tooth brushing technique is the recommended brushing time. The American Dental Association recommends a minimum two-minute brushing time twice per day. Unfortunately, children often get bored during the two-minute time period and finish brushing prematurely. Toothbrushes having cartoon characters, lights, or other attention grabbing features have been developed to keep a child engaged throughout the brushing process. However, the child may lose interest and rush through brushing. Although child dentifrices exist to encourage brushing (e.g., dentifrices with a pleasing taste), these dentifrices do not encourage or teach proper brushing techniques nor educate the parent or child about the importance of proper brushing techniques.
Thus, there exists a need for a dentifrice and method to promote proper brushing and rinsing techniques. There further exists a need for a dentifrice to help educate a parent and child about the caries process, tooth decay, and cavity formation associated with poor brushing and rinsing techniques.
The present invention generally relates to the field of dentifrices for teeth cleaning, and more particularly to a new and useful dentifrice to promote proper tooth brushing techniques.
The general purpose of the dentifrice, described subsequently in greater detail, is to provide a dentifrice which has many novel features that results in the teaching and adoption of proper tooth brushing techniques, which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof.
The dentifrice generally includes a carrier material and a plurality of persistent particles in the carrier material. The persistent particles are resilient to friction when subjected to tooth brushing and visually distinguishable from the carrier material when the dentifrice is expelled from one's mouth to act as an indication to continue tooth brushing and signal when rinsing is complete. The persistent particles may be made of a resilient insoluble, non-toxic, and non-abrasive material such as polymeric tinsel or glitter to maintain the general shape of the particles throughout the brushing process. The particles may be visually non-distinguishable from the carrier material prior to brushing to not stand out when the dentifrice is dispensed on a toothbrush. The concentration of the particles in the carrier material may further require the tooth brusher to properly brush for two to three minutes before all of the particles are expelled from the tooth brusher's mouth to ensure the tooth brusher brushes for the recommended brushing time.
A method is also provided for using the dentifrice to promote proper tooth brushing techniques. The method includes brushing one's teeth with the dentifrice described herein including: 1. expelling the dentifrice from one's mouth; 2. identifying if any persistent particles are in the expelled dentifrice; 3. continuing to brush and expel the dentifrice if any persistent particles are identified in the expelled dentifrice; and 4. rinsing the dentifrice from one's mouth when no persistent particles are identified in the expelled dentifrice. The method may further include educating the one about bacteria associated with tooth decay using the persistent particles as a teaching tool.
Thus has been broadly outlined the more important embodiments and features of the dentifrice so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
Advantages of embodiments of the present dentifrice, along with various novel features that characterize the invention are particularly pointed out in the claims forming a part of this disclosure. For better understanding of the various embodiments of the dentifrice, and its operating advantages attained by its uses, refer to the accompanying drawings and description.
The present invention has utility as a dentifrice and method of use to promote proper tooth brushing and rinsing techniques, especially for children. The dentifrice is additionally useful as a teaching tool to educate parents and children about cavity formation and oral hygiene in general. The following description of various embodiments of the invention is not intended to limit the invention to these specific embodiments, but rather to enable any person skilled in the art to make and use this invention through exemplary aspects thereof.
It is to be understood that in instances where a range of values are provided that the range is intended to encompass not only the end point values of the range but also intermediate values of the range as explicitly being included within the range and varying by the last significant figure of the range. By way of example, a recited range from 1 to 4 is intended to include 1-2, 1-3, 2-3, 2-4, and 1-4.
With reference now to the drawings,
The carrier material 102 is generally composed of one or more materials configured to clean one's teeth and provide the vehicle for the persistent particles 104. The carrier material 102 may be a paste, liquid, gel, or powder for cleaning teeth known in the art. In a specific embodiment, the carrier material 102 is a children's toothpaste.
The plurality of persistent particles 104 may be made of one or more materials that are resilient to friction when subjected to tooth brushing and visually distinguishable from the carrier material when expelled from one's mouth. In other words, the persistent particles 104 are made of one or more materials capable of withstanding the friction generated during tooth brushing such that the particles generally maintain their original shape throughout brushing. The resilient material(s) of the persistent particles 104 may further be insoluble in the carrier material 102, or at least insoluble in the majority ingredient of the carrier material 102, so the particles 104 do not dissolve during brushing or while the dentifrice 100 is stored. The material(s) of the particles 104 may further be non-toxic so as not to harm to the tooth brushers general health if the particles 104 are accidentally ingested. In addition, the material(s) of the particles 104 may be non-abrasive to avoid scratching, cutting, or irritating the tooth brushers gums, teeth, lips, or cheeks. Conversely, the material(s) of the particles 104 may be slightly abrasive, or have an abrasive surface, to act as a polishing agent. In a specific inventive embodiment, the particles 104 are made of insoluble, non-toxic, and non-abrasive polymeric tinsel or glitter. In other embodiments, the particles 104 are made of a natural material or glitter that is minimally soluble in the carrier material 102. In some embodiments, the minimum solubility is characterized by the persistent particles 104 completely dissolving in the carrier material 102 within 1 month to 1 year. In other embodiments, the minimum solubility is characterized by the persistent particles 104 completely dissolving in the carrier material 102 in 1 to 3 years. In a further embodiment, the minimum solubility is characterized by the persistent particles 104 completely dissolving in the carrier material 102 in greater than 3 years.
In a specific inventive embodiment, with reference to
In addition to the shape of the persistent particles 104, the persistent particles 104 have dimensions and or properties that permit the particles 104 to be visually distinguishable from the carrier material 102 when the dentifrice 100 is expelled from one's mouth. Preferably, the dimensions of the persistent particles 104 are small enough so as to not irritate the gums, teeth, or cheeks during brushing, but large enough to be seen by the naked eye in the dentifrice 100 when expelled. In a particular embodiment, the persistent particles 104 have a minimum size in the range of 0.1 mm to 2 mm, where 0.1 mm is generally regarded as the smallest visual resolution of a human naked eye. In another embodiment, the persistent particles 104 have dimensions ranging from 0.1 mm-2 mm (length)×0.1 mm-2 mm (width). In a further embodiment, the persistent particles have a minimum diameter ranging from 0.1 mm-2 mm.
The persistent particles 104 may include other properties to be visually distinguishable from the carrier material 102 when the dentifrice 100 is expelled from one's mouth. For example, the persistent particles 104 may have a color different from a color of the carrier material 102 when expelled. The persistent particles 104 may have an albedo or reflectance different from an albedo or reflectance of the carrier material 102 when expelled. The persistent particles 104 may have both a color and albedo different from the carrier material 102 when expelled.
In a specific inventive embodiment, the persistent particles 104 are visually non-distinguishable from the carrier material 102 prior to brushing one's teeth such that the particles 104 do no stand out when the dentifrice 100 is dispensed onto a toothbrush. The carrier material 102, prior to brushing, may have a color, gradient, or visual pattern to camouflage the persistent particles 104 therein. The carrier material 102 may change color throughout the brushing process (common of many dentifrices) such that the persistent particles 104 are visually distinguishable from the carrier material 102 when the dentifrice 100 is expelled. For example, prior to brushing, the carrier material 102 and the persistent particles 104 may be green in color. When the dentifrice 100 is expelled, the carrier material 102 may be white, where the persistent particles 104 maintain their green color and are therefore visible in the expelled dentifrice 100.
In a specific inventive embodiment, the persistent particles 104 have glow in the dark properties. The persistent particles 104 may be coated, painted, or at least partially made with phosphorescent materials known in the art. The particles 104 are charged by exposure to light and then illuminate in the dark. The particles 104 with phosphorescence may be camouflaged in the carrier material 102 while the user brushes their teeth in the light, and upon turning off the lights the particles 104 illuminate in the dark. The use of particles 104 having phosphorescence improves the brushing experience and further encourages a user to brush their teeth.
In a particular inventive embodiment, the plurality of persistent particles 104 in a single serving size of dentifrice 100 exists in a quantity, mass percentage, or volume percentage that requires 2 to 3 minutes of proper brushing technique to remove all of the particles 104 from one's mouth. Therefore, with a proper brushing technique the tooth brusher brushes for at least the recommended 2-minute minimum brushing time. Longer brushing times, to remove all of the persistent particles 104, may occur if improper brushing techniques are used, which incentivizes the tooth brusher to learn and adopt a proper brushing technique. The single serving size of dentifrice 100 may be 0.2 gram to 0.3 grams. In a specific embodiment, the persistent particles 104 constitute 0.1% to 5% by volume in the carrier material 102.
The dentifrice 100 may be manufactured using techniques know in the art. The persistent particles 104 may be mixed in the carrier material 102 during the dentifrice 100 manufacturing process using a standard industrial mixing technique.
