Definitions
- the present invention relates to toothbrushes, and particularly to a toothbrush having textured bristles.
- Teeth cleaning is the removal of dental plaque and tartar from teeth in order to prevent cavities, gingivitis, and gum disease. Severe gum disease causes at least one-third of adult tooth loss. Almost all cavities occur where food is trapped between teeth, inside deep pits, and fissures in grooves on chewing surfaces where the brush, toothpaste, mouthwash, saliva, and chewing gum, cannot reach. Careful and frequent brushing with a toothbrush, along with the use of dental floss, help to prevent build-up of plaque bacteria on the teeth. These bacteria metabolize carbohydrates in meals or snacks and excrete acid which demineralizes tooth enamel, eventually leading to tooth decay and toothache, if acid episodes are frequent or are not prevented.
- teeth be cleaned professionally at least twice per year. Professional cleaning includes tooth scaling, tooth polishing, and, if too much tartar has built up, debridement. This is usually followed by a fluoride treatment for children and adults. Between cleanings by the dentist or dental hygienist, good oral hygiene is essential for preventing tartar build-up. This is performed by carefully and frequently brushing with a toothbrush and the use of dental floss to prevent accumulation of plaque on the teeth.

Description
- This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/136,612, filed Sep. 18, 2008.
- 1. Field of the Invention
- The present invention relates to toothbrushes, and particularly to a toothbrush having textured bristles.
- 2. Description of the Related Art
- Teeth cleaning is the removal of dental plaque and tartar from teeth in order to prevent cavities, gingivitis, and gum disease. Severe gum disease causes at least one-third of adult tooth loss. Almost all cavities occur where food is trapped between teeth, inside deep pits, and fissures in grooves on chewing surfaces where the brush, toothpaste, mouthwash, saliva, and chewing gum, cannot reach. Careful and frequent brushing with a toothbrush, along with the use of dental floss, help to prevent build-up of plaque bacteria on the teeth. These bacteria metabolize carbohydrates in meals or snacks and excrete acid which demineralizes tooth enamel, eventually leading to tooth decay and toothache, if acid episodes are frequent or are not prevented. Calculus or tartar buildup on teeth usually forms opposite salivary ducts due to calcium deposits in resident plaque. Frequent brushing and swishing of saliva around the mouth helps prevent these deposits: Cavities can be costly, in terms of the monetary cost to drill out the cavities and insert dental fillings, and also in terms of the tissue already damaged.
- Generally, dentists recommend that teeth be cleaned professionally at least twice per year. Professional cleaning includes tooth scaling, tooth polishing, and, if too much tartar has built up, debridement. This is usually followed by a fluoride treatment for children and adults. Between cleanings by the dentist or dental hygienist, good oral hygiene is essential for preventing tartar build-up. This is performed by carefully and frequently brushing with a toothbrush and the use of dental floss to prevent accumulation of plaque on the teeth. Thus, brushing of the teeth is universally recommended as the most effective way to maintain oral hygiene.
- A wide variety of toothbrushes and other home dental cleaning implements have been used for centuries, however none are as effective as the scraping, debridement and other abrasive-based operations performed by dental professionals. Thus, a toothbrush with textured bristles solving the aforementioned problems is desired.
- The toothbrush with textured bristles provides a tooth cleaning implement that allows for a greater abrasive or scrubbing effect than that of a conventional toothbrush. The toothbrush with textured bristles includes an elongated handle having a head portion, as is conventionally known in toothbrushes, and a plurality of bristles extending from the head portion. Each of the bristles is formed from a non-porous material and has opposed fixed and free ends with a side surface being defined therebetween. The side surface is textured to abrade the user's teeth during brushing thereof. The textured side surface may be formed as a substantially helical surface having alternating helical ridges and helical grooves or, alternatively, the bristle may be formed as a central shaft with a plurality of spaced apart rings annularly formed thereon.
- These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.
-
FIG. 1 is an environmental, perspective view of a head of a toothbrush with textured bristles according to the present invention. -
FIG. 2 is a perspective view of a bristle for the toothbrush having textured bristles according to the present invention. -
FIG. 3 is a side view of an alternative embodiment of the bristle of the toothbrush having textured bristles according to the present invention. -
FIG. 4 is a side view of another alternative embodiment of the bristle of the toothbrush having textured bristles according to the present invention. - Similar reference characters denote corresponding features consistently throughout the attached drawings.
- Referring to
FIG. 1 , the toothbrush with textured bristles has anelongated handle 10 having ahead portion 12. Thehandle 10 may have any desired length or shape, such as that commonly associated with typical toothbrushes. Thehead portion 12 has a plurality ofbristles 14 extending outwardly therefrom. Thebristles 14 are preferably formed from a non-porous plastic material that is easily cleanable, preferably by simply rinsing with water from a typical household faucet, as is conventionally known. - The
bristles 14 are substantially cylindrical, eachbristle 14 preferably having the same predetermined diameter, and having the same length as those of a conventional toothbrush. Each of the plurality ofbristles 14 has one end fixed to thehead portion 12 by any suitable method, as is conventionally known in the arts of general brushes and toothbrushes, and an opposite free end ortip 15 for contacting the user'steeth 16. - The plurality of
bristles 14 function similarly to those of a conventional toothbrush. With a normal stroke, the plurality ofbristles 14 brush a desiredouter surface area 18 of theteeth 16. Thetips 15 of thebristles 14 lightly abrade and brush thesurface area 18 of theteeth 16, as well as guiding thebristles 14 into the spaces formed between theteeth 14, and under the gums, under bridges, unfit caps, or other difficult-to-reach areas, particularly in the back of the user's mouth.Bristles 14 are formed from a resilient material, and as eachtip 15 lightly abrades and scrubs the desiredsurface area 18 of theteeth 16, aside surface 19 of each of thebristles 14 also lightly abrades and brushes thedesired surface area 18 of theteeth 16. - The
bristles 14 ofFIG. 1 may have any desired texturing on the side surfaces thereof, allowing for increased abrasion during brushing. In a first embodiment, represented by the single exemplary bristle 20 (one of the plurality ofbristles 14 ofFIG. 1 ) shown inFIG. 2 , between the fixed end of the bristle 20 (i.e., the end ofbristle 20 which is secured to the head 12) and thetip 15, thebristle 20 is twisted or coiled to form a helical surface. The twisted or helical shape of thebristle 20 provides a number oftextured surfaces 19 a, 19 b, 19 c formed by the alternating helical ridges and grooves on the surface of thebristle 20. - Relative to a conventional toothbrush bristle,
bristle 20 has a greatly increased surface area with preferably dozens of microscrubbing contact surface areas formed by the longitudinally extending ridges of the helical surface for bearing against theteeth 16. Thus, as opposed to a conventional, smooth, cylindrical bristle,bristle 20 contacts and scrubs the teeth with both thetip 15 and each of thetextured surfaces 19 a, 19 b, 19 c, etc. In addition to the abrasion of the textures surfaces 19 a, 19 b, 19 c, when brushing the teeth, thehelical bristle 20 is able to move back and forth. entrapping microscopic food particles and other particles and contaminants, which become lodged in the valleys formed between each ridge of the surface. - In the alternative embodiment of
FIG. 3 , the exemplary bristle 30 (one of the plurality ofbristles 14 ofFIG. 1 ) is attached to thehead 12 of the toothbrush at a fixed end thereof (similar to that described above), and has a free end ortip 35. Between the fixed end and thetip 35, thebristle 30 includes a number of spaced apart ring members orannular beads ring members FIG. 3 for exemplary purposes only, and may have any desired shape, relative dimensions or spacing therebetween. For example, the ring members may be rounded, squared, angled, or may have any other desired contour. As withbristle 20, thering members bristle 30 form additional surfaces along the length of thebristle 30 for abrading the desired surface area ofteeth 16, and also allow for the collection and removal of particles and the like between adjacent ring members. - In the embodiment of
FIG. 3 , the rings are each shown as having a substantially rounded peripheral surface. It should be understood that therings FIG. 4 , or angled, sloped, or of any other cross-sectional shape. It should be further understood that the shape of thebristles FIGS. 1-4 , the texturing of the side surface of each bristle is shown as extending along the entire length of the bristle. It should be understood that the texturing may cover only a selected portion of the bristle, with the remaining portion being substantially smooth and cylindrical. - Thus, it is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
