Description

Interdental brush

Technical Field

The utility model belongs to the technical field of instrument for the oral cavity is clean, concretely relates to interdental brush for cleaning tooth nest ditch and slit.

Background

Teeth, also known as "teeth", have a certain form of highly calcified tissue with the function of chewing, assisting in the pronunciation and maintaining the facial appearance.

Dental caries, commonly known as decayed tooth and decayed tooth, is a bacterial disease and can cause secondary pulpitis and periapical periodontitis, and even alveolar bone and jaw inflammation. If not treated in time, the lesion continues to develop, forming a cavity, eventually the crown is completely destroyed and disappears, the end result of which is the loss of teeth. Dental caries is characterized by high incidence rate and wide distribution. Is a main common disease of the oral cavity and is one of the most common diseases of human beings, and the world health organization combines the common disease with tumor and cardiovascular disease as three major key diseases for preventing and treating the diseases of the human beings. Therefore, tooth cleaning and prevention of dental caries are very important.

The greatest cause of the occurrence of dental caries is that in order to remove foreign substances between teeth, which are difficult to be cleaned with a general toothbrush, after people ingest food, the foreign substances between the teeth are removed using a toothpick or a toothbrush, which is sharply formed at one or both ends. Namely, toothpicks and interdental brushes are used for preventing dental caries and periodontal disease.

More specifically, toothpicks are made of wood, plastic, starch, and are used in removing food debris between teeth. In this case, if the interval between teeth is narrow, the end of the sharp tip of the toothpick is difficult to enter between teeth, so that it is difficult to remove food waste, and there is a problem that the end of the sharp tip is hard and the end of the sharp tip is easily broken, thereby causing inconvenience to a user.

In order to solve the above problems, an interdental brush having a brush attached thereto is manufactured and used.

Generally, an interdental brush includes: a toothbrush body that a user can hold with a hand; and a head formed at one side end of the toothbrush body. And, the wire rod: and a brush inserted between the two wires twisted with each other and fixed. That is, the interdental brush removes food waste by the action of the wire advancing and retreating from the gap between the teeth and the brush rubbing between the teeth.

However, in the conventional interdental brush, bristles are too soft to affect a cleaning effect, and too hard to easily damage teeth and gums, and the bristles are fixed to a wire in a circular shape and a brush rod is in a linear shape, so that there is a limitation in that the bristles deeply enter between a gum of a user and two teeth connected to the gum.
