Description

Dental plaque cleaner

Technical Field

The utility model relates to a clean technical field of dental plaque particularly, relates to a dental plaque cleaner.

Background

Dental plaque is a matrix-encapsulated, soft, unmineralized bacterial population that adheres to each other or to the surface of the tooth, interdental, or prosthetic surfaces, a bacterial biofilm that cannot be washed or rinsed away with water. Plaque constitutes a major hazard to the teeth and gums, resulting in two of the most common diseases of the oral cavity: caries and periodontal disease. Caries is commonly known as "caries" where the "worm" refers to bacteria in the plaque. Plaque adheres firmly to the tooth surface, and the bacteria ingest the sugars in the saliva, breaking down the sugars and producing acids, which can damage the teeth and eventually create cavities. When plaque is brought close to the gums, the bacteria produce toxins and other harmful substances that irritate the gums, producing inflammation, i.e., gingivitis. If left uncontrolled, gingivitis may develop into irreversible periodontitis, causing destruction of the alveolar bone, which may eventually lead to loosening and loss of teeth.

If the dental plaque is not cleaned in time, the dental plaque is calcified to form dental calculus; after tartar has formed, it cannot be removed using daily oral care methods, and can only be removed with specialized equipment, seeking the assistance of a professional. Tooth brushing is a well-known oral care method, and is also the most basic and primary method of removing plaque. The teeth are brushed first in the morning and evening, which is particularly important. Food residues on the tooth surface are not removed in time, so that abundant nutrient substances are provided for bacteria, the bacteria can be proliferated in a large amount, and simultaneously more harmful substances are generated, and saliva secretion is reduced in sleeping, so that the harmful substances cannot be well neutralized and diluted, and serious harm can be caused to teeth.

However, when the amount of dental plaque is small, the dental plaque is difficult to observe by naked eyes, so that the dental plaque is difficult to remove in a targeted manner by general tooth brushing, in the prior art, a color developing agent is used for developing the color of the dental plaque firstly, and then a toothbrush is used for cleaning, but the two objects are used separately, so that the operation is complicated, and the tooth brushing force cannot be adjusted according to the size and the severity of the dental plaque, so that the cleaning effect is poor; the dental plaque is detected by arranging the fluorescence detection unit on the brush hair wall of the toothbrush, but the detection is easy to be inaccurate due to the occlusion of tooth brushing.
