Interdental brush structure and dental floss stick with the structure

This writing is about a dental floss stick, especially a dental floss bar with a scalloped conical interdental brush structure designed to completely clean the interdental food residue and plaque.

Common oral cleaning products currently on the market include toothbrushes, toothpastes, mouthwashes, and flossing products. When eating, foods are easily caught between the teeth of two adjacent teeth by chewing, and are used with a toothbrush after eating. Toothpaste may not completely remove the food residue in the tooth gap, and the mouthwash may not be able to completely remove the food residue from the tooth gap. At this time, the food residue stuck in the tooth gap is removed by flossing. This prevents bacteria from using the food residue to reproduce in the oral cavity, and at the same time avoids the influence of the food residue in the interdental joints. Therefore, flossing after meals is a simple, quick and convenient method of cleaning teeth.

Generally, the daily necessities for cleaning the oral cavity to keep the teeth healthy are mostly toothbrushes, toothpicks or dental floss. However, except for the soft part of the toothbrush, the rest is extremely tough. Even if the toothbrush is shaped like a tooth, it is not easy to remove the root or The dirt between the teeth is then cleaned with a toothpick or dental floss. The toothpick can remove the residual food between the teeth, but it is very easy to damage the enamel and cause damage to the surface of the tooth. Although the dental floss can penetrate between the teeth, only It can scrape the residue of the lightly attached food, and can not thoroughly clean the roots or the teeth. Therefore, there are products for interdental brushing to thoroughly clean the teeth and maintain oral hygiene.

For the convenience of use, the interdental brush develops an interdental brush with a changeable angle to facilitate the cleaning of the user's teeth. Among them, the bulletin number 279341 is a changeable angle interdental brush, which is a handle and a joint body. And the brush is formed, the joint body can be folded at an angle with respect to the handle, and the brush has flexibility, so that the angle can be bent, so that the brush can be easily bent to more than 90 degrees, but When the angle is bent, the user needs to touch the brush with the hand to bend the angle of use.
