Abstract
A brush head and a toothbrush with the brush head are provided. The brush head includes a body having a front end, a back end opposing the front end, and two opposite sides; and a brush member mounted on a surface of the body and being formed with a plurality of bristles, wherein the plurality of bristles define a brush surface that slopes in relation to the surface of the body. The brush surface of the bristles can closely abut against the teeth and the gingival sulcus, and the cleaning effect of tooth brushing is efficiently enhanced using the toothbrush with the brush head, thereby overcoming the drawbacks of the prior art.
Description
- The present invention relates to cleaning technologies, and more particularly, to a brush head and a toothbrush with the brush head for cleaning teeth.
- Healthy teeth not only allow people to eat normally but also enable people to fully enjoy delicacies during chewing. Various bacteria abound in the oral cavity where food is mixed with saliva, which, coupled with bacterial reactions, accounts for the formation of dental plaque in the gingival sulcus. Given time, the aforesaid reactions cause periodontal disease and dental caries.
- More particularly, pathogenesis of periodontal disease is as follows: dental plaque and bacteria in the gingival sulcus cannot be thoroughly cleaned; however, accumulation and calcification of dental plaque in the gingival sulcus lead to the formation of dental calculus, a dental term. Once dental calculus is formed, cleaning the gingival sulcus becomes more difficult, which is an initial symptom of periodontal disease. Then, there are inflammation, bleeding, redness and sore swellings in the gingiva; at this point, where the disease is not diagnosed and treated in time by a dentist to remove dental calculus and dental plaque, periodontal disease is right around the corner. Eventually, loss of periodontal alveolar bone and formation of periodontal pockets take place, resulting in severely loosened teeth and even tooth loss.
- In addition, pathogenesis of dental caries is as follows: in the presence of the dental plaque and bacteria adhering to the teeth, food in the oral cavity is metabolized into acidic substances which, in turn, decalcify the calcified structure of the teeth, and then invasion (decay) which is initially limited to enamel extends to dentine step by step; meanwhile, dental pulp (commonly referred to as nerve) cell processes inside the dentine tubules of dentine transmit heat and cold from dentine to dental pulp, which results in pulpitis. Pulpitis causes intense tooth pain, which is commonly referred to as a toothache killing the patient.
- Accordingly, as regards dental hygiene, dentists often recommend brushing teeth four times a day, that is, after meals and before bedtime everyday. In so doing, not only is the oral cavity cleaned and its odor removed, but also the teeth are free from diseases. Hence, to get sparkling white teeth, one has to have a good understanding of tooth brushing first. At present, according to the most internationally recommended Bass Method for brushing teeth, one should direct the toothbrush toward the roots of the teeth at an angle that ranges between 45° and 60° and then brush the surfaces of the teeth upward and downward. Despite the high efficiency Bass Method, a well-selected, good toothbrush is indispensable to an efficient, health-promoting daily tooth-brushing task.

FIGS. 1A and 1B illustrate toothbrushes on the market. Atoothbrush 10 typically has abrush head 101 and ahandle 103, whereinbristles 1011 which form a brush member of thebrush head 101 are usually designed in such a way that they have the same length. As shown inFIGS. 2A through 2C , various brands of toothbrushes differ mostly in terms of the size of thebrush head 101 and the tip angle of thebrush head 101, so as to facilitate manipulation of thebrush head 101 in the oral cavity.FIGS. 3A and 3B depict a special design whereinbristles 2011 at the front of thebrush head 201 of thetoothbrush 20 are relatively long and form an inclined surface, to clean the teeth on the distal best. As regards the related patented technology, an example is Taiwanese Patent No. 264649 that proposes a toothbrush wherein bristles disposed at the front and on both sides of the brush head are longer than those disposed at the back and the middle of the brush head. - However, where a toothbrush with bristles of the same length is used, good tooth brushing skills are required to keep the oral cavity clean. Even if the
toothbrush 20 illustrated byFIGS. 3A and 3B and that proposed in Taiwanese Patent No. 264649 is adopted, it would be impossible to stretch the cheeks with the toothbrush, thus tooth brushing can only be carried out in a nearly parallel direction, and any attempt to remove dental plaque from the gingival sulcus and tooth surfaces is always ineffective. - The lingual side of the teeth on anterior maxilla and anterior submaxilla (i.e., lingual surfaces of the teeth) forms an arch, which is inaccessible to a toothbrush. However, none of the designs of the brush head based on the aforementioned known technology fulfills the dual requirements for solving the inaccessibility problem and cleaning the occlusive surface.
- As described above, the designs of the brush head and bristles of the toothbrushes on the market greatly compromise the cleaning efficiency of tooth brushing. The general public does not possess the oral cavity cleaning skills expected of dentists or dental professionals. As a result, periodontal disease and dental caries prevail, and dental clinics abound.
- Accordingly, an issue that needs urgent solution involves developing a tooth cleaning technique to overcome various drawbacks of the aforesaid conventional technology, make tooth brushing simple and easy, and achieve the purpose of cleaning the oral cavity without using any well-recognized tooth brushing technique.
- Accordingly, to solve the drawbacks of the aforementioned conventional technology, it is a primary objective of the present invention to provide a brush head capable of enhancing the cleaning efficiency of tooth brushing and a toothbrush with the brush head, so as to clean the gingival sulcus and the teeth efficiently.
- It is another objective of the present invention to provide a brush head and a toothbrush with the brush head, so that tooth brushing becomes simple and easy, and the oral cavity is cleaned without using any well-recognized tooth brushing technique.
- It is still another objective of the present invention to provide a brush head and a toothbrush with the brush head, so as to meet the dual requirements for solving the inaccessibility problem and cleaning the occlusive surface.
- It is a further objective of the present invention to provide a brush head and a toothbrush with the brush head, to increase design flexibility.
- In order to achieve the above and other objectives, a brush head and a toothbrush with the brush head are provided according to the present invention. The brush head comprises a body having a front end, a back end opposing the front end, and two opposite sides; and a brush member mounted on a surface of the body and being formed with a plurality of bristles, wherein the plurality of bristles define a brush surface that slopes in relation to the surface of the body.
- Preferably, the front end of the body of the brush head includes a fixing portion, which is, for example, either a protruding bump or a protruding rib. The front end of the body may further comprise a first bonding portion, which is, for example, a recessed portion. The back end of the body of the brush head may also comprise a fixing portion, which is, for example, either a protruding bump or a protruding rib. The back end of the body may further comprise a second bonding portion, which is, for example, a recessed portion. The plurality of bristles comprise bristles of different lengths. In a preferred embodiment, the brush surface of the brush member slopes in a direction toward one of the two opposite sides of the body of the brush head. In another preferred embodiment, the brush surface of the brush member slopes in an opposite direction toward the other one of the two opposite sides of the body of the brush head. The brush surface may have a parabolic profile. The body of the brush head further includes an opening and two grooves respectively disposed on two sides of the opening.
- The present invention further provides a toothbrush comprising the aforementioned brush head and a handle coupled to the brush head. Preferably, the brush head and the handle are integrally formed or separately formed. The front end of the body of the brush head comprises the first bonding portion, the back end of the body of the brush head comprises the second bonding portion, and the handle comprises a receiving portion and a third bonding portion. The receiving portion is, for example, a recessed portion.
