Description

An adjustable and replaceable toothbrush

technical field

The utility model relates to the technical field of oral health, in particular to a toothbrush with an adjustable and replaceable brush head.

Background technique

Dental calculus is mainly composed of protein in saliva and food residues, as well as bacterial plaque, bacteria in the oral cavity and other complex substances, and most of them accumulate at the opening of the salivary gland duct. There are salivary gland ducts on the lingual side of the mandibular anterior teeth Therefore, it can be seen clinically that many patients have the most and thickest calculus on the lingual side of the mandibular anterior teeth. Dental plaque can lead to gingivitis, periodontitis, and lead to receding gums.

The existing bristles are directly implanted into the bristle-planted surface of the brush head. When brushing your teeth, you need to use the Papanicolaou method, which is a method recommended by the American Dental Association to effectively remove plaque near the gingival margin and in the gingival sulcus. Point to the root tip at a 45° angle with the long axis of the tooth, so that the bristles partly enter the gingival sulcus, and partly spread on the gingival margin, and extend into the adjacent gap as much as possible. Use gentle pressure to make the bristles short in the front and rear directions. The level of the distance flutters 4-5 times. However, many people do not know the correct method of brushing teeth, and the Pap method is also difficult to master, and the brushing time is short, and the ideal cleaning effect cannot be achieved, which eventually leads to the accumulation of dental calculus.

Most toothbrushes on the market are non-adjustable between the brush head and the handle. The overall shape of the toothbrush is fixed. The flocking surface is on the same horizontal plane. The above-mentioned type of toothbrush is effective for cleaning most areas of the teeth, but is not conducive to cleaning the lingual area, especially the lingual area of the front teeth. At the same time, most existing toothbrushes cannot adjust the angle of the brush head, and the brush head cannot be replaced, which is not conducive to environmental protection and causes waste of resources.
