According to the most recent World Health Organization (WHO) Oral Health Status Report, nearly half of the world's population suffers from oral diseases, such as dental decay, gum disease, and oral cancers. Gum disease is the leading cause of complete tooth loss, affecting an estimated one billion individuals worldwide. Plaque accumulation on teeth causes gum disease by triggering an inflammatory response that damages periodontal tissue and the bone that supports the teeth. As the disease advances, the gums may recede and the teeth may become loose or fall out.

In addition to tooth loss, periodontal disease has been linked to a number of other health problems. The bacteria responsible for gum disease may enter the bloodstream and cause inflammation in other regions of the body, which may contribute to the development of cardiovascular disease, stroke, and diabetes, according to research. In addition, expectant women with periodontal disease may have an increased risk of preterm birth and low birth weight.

Given the prevalence of periodontal disease and its association with a variety of health problems, it is regarded as a major global public health concern. Regular dental exams, good oral hygiene, and a healthy diet can reduce the risk of tooth loss and enhance overall health outcomes by detecting and preventing gum disease.


The Lemelson-MIT Invention Index is an annual survey that assesses Americans' perspectives on inventions and innovation. In 2003, respondents were asked to choose which of five inventions they could not live without: the toothbrush, the automobile, the personal computer, or the cell phone. 42% of respondents selected the toothbrush as the most important invention.

Although toothbrushes play a vital role in sustaining good oral hygiene, their design and technology have not advanced as rapidly as those of the automobile or computer industries. The bristle toothbrush, similar to those in use today, was invented and made in China during Tang Dynasty (618-907). The bristles were actually stiff, coarse hairs from the back of a pig's neck that were attached to bone or bamboo handles.

In 1938, DuPont de Nemours introduced nylon bristles, which replaced boar bristles. The name of the first nylon toothbrush was Doctor West's Miracle Toothbrush. The disciplined hygiene practices of American Civil War soldiers influenced later generations of Americans. They became increasingly concerned with the practice of good oral hygiene and swiftly adopted the nylon toothbrush. The introduction of nylon bristles marked a turning point in toothbrush technology and paved the way for further advancements in oral hygiene. Today, toothbrushes continue to evolve and offer a range of features and benefits to help people maintain good oral health. However, the clinical needs have changed rapidly over the years, which make oral care more sophicated. Until late 80s, anti-cavity and anti-plague were the main focus of oral care product development. Today, gingival sulcus care has become increasingly important for oral hygiene. The gingival sulcus is a V-shaped fissue that encircles each tooth and is bordered by the tooth on one side and the epithelium lining the free margin of the gingiva on the other. Despite being an important part of the dental anatomy, the sulcus can be problematic for oral health. Bacteria tend to thrive in the sulcus because it is resistant to the cleaning action of saliva. Additionally, gingival fluid, also known as sulcular fluid, provides a rich source of nutrients for microorganisms, further contributing to bacterial growth. Therefore, it is important to maintain good oral hygiene practices with products that can truly provide the perfect oral hygiene protection.

The filament sharpening technology ensures that the tips are precise and durable, making them ideal for cleaning gingival sulcus and maintaining healthy teeth and gums. The yamagata surface structure is a proprietary design that allows the bristles to penetrate deep into the gingival sulcus. This enables the toothbrush to effectively remove food particles, plaque, and bacteria from the hard-to-reach areas of the mouth. Additionally, the sandwich type brush wire layout helps to provide an even distribution of pressure across the bristles, ensuring a gentle but thorough clean. This layout also supports the Bass method of brushing, which is a clinical recommended technique for maintaining healthy gums.The toothbrushes from DR BEI are anchorless tufting with nickel silver, a material that is both secure and resistant to bacterial growth. The toothbrush handle is manufactured from food-grade materials, making it safe for oral use.

The electric toothbrushes of DR BEI are equipped with high-speed magnetic levitation acoustic technology delivering up to 40,000 times per minute and an elastic rotation structure for superior cleansing results. DR BEI has applied the stepless acceleration principle of racing cars to their electric toothbrush motor design. This enables users to enjoy a stepless power adjustment, which can be tailored to meet a variety of oral cleaning needs. Each electric toothbrush is fitted with different brushing modes and brush heads to provide comprehensive and individualized oral care. Furthermore, it comes with pressure-sensing smart technology and elastic shock absorbers that are seamlessly integrated for automatic power adjustment to prevent gum injury. The noise reduction technology enables a reduced noise level to less than 55 decibels. The toothbrush's battery provides from 30 days up to 180 days of use on a single charge, depending on different modes, making it a convenient option for travelers and individuals who are constantly on the move. The toothbrush is also equipped with IPX7 water-resistant technology, which provides exceptional protection against water damage. This feature allows the toothbrush to remain operative even after socked in 1 meter depth of water for 30 minutes.
