Patent Description:
Due to reasons such as aging, pathology, and the like, gingival atrophy is easily caused, and a gap between teeth is easily expanded, thereby causing food residues. If the residues are not cleaned in time, not only oral odor may be generated, but also various dental diseases, oral diseases, and especially periodontitis are easily caused.

Dental floss is an important interdental cleaning tool on the market. Although there are various products with different structures and specifications on the market, the existing products are generally difficult to observe the gap between teeth. Especially, when a gap between a third molar and a second molar, or a gap between the second molar and a first molar, or a gap between the first molar and the second molar is cleaned, because a position of the gap between the teeth to be cleaned is located deep in an oral cavity, light in a cleaned part is very dark. When there is no external lighting, a user can only operate by feeling, which will easily cause bleeding or damage to gums. Therefore, the existing dental floss needs to be improved.

<CIT> describes a reusable handle for use with a disposable dental flosser having an electrical circuit located within the handle for operating an illumination source to illuminate floss of the flosser and an area of interest during use of the flosser at the area of interest.

<CIT> describes a built-in interdental brush having an interdental brush body that is arranged in a bend of a guide head of a delivery device. After the guide head is aligned with gaps between teeth, a sliding mechanism on the delivery device is pushed to drive a working part of the interdental brush body made of elastic materials to be automatically bent along the radian of the bend to be aligned with and enter the gaps between the teeth. The working part of the interdental brush body moves in the gaps between the teeth back and forth by repeatedly pushing and pulling a sliding block on the sliding mechanism of the delivery device to clean the gaps between the teeth. The delivery device has good rigidity such that after an outlet of the bend of the guide head of the delivery device is aligned with the gaps between the teeth, the pushed-out interdental brush body directly enters the gaps between the teeth. As the outlet of the bend of the guide head of the delivery device is almost attached to the gaps between the teeth and is quite close to the gaps between the teeth, the interdental brush body is not prone to being bent and the controllability of the interdental brush body is improved. A lighting system and an observing system are additionally arranged in the built-in interdental brush to illuminate the mouth cavity.

<CIT> describes a flosser illumination system which provides a flosser and an illumination device that is removably positionable on the flosser for illuminating the mouth during flossing.

The invention is defined by a luminous dental floss tool with the features of claim <NUM>.

The luminous dental floss of the present application is illuminated by a light source system to ensure that a cleaned part may be clearly observed in a cleaning process, thereby effectively preventing accidental damage to gums while ensuring the cleaning effect.

The illumination system <NUM> is designed on the handle <NUM> of the luminous dental floss of the present application, and the illumination light emitted by the light source system <NUM> of the illumination system <NUM> can illuminate the oral cavity. The dental floss is used to clean a gap between teeth with enough light, thereby effectively preventing the dental floss from accidentally damaging gums during cleaning while ensuring the cleaning effect. Through the detachable connection mode, the dental floss <NUM> can be replaced in time after use, so that the use process is cleaner and more hygienic.

The observation window <NUM> provided between the working portion <NUM> and the connecting portion <NUM> may better observe the clean part, and the observation window <NUM> is usually designed as a triangle.

The dental floss <NUM> is made of a light guide material. The dental floss <NUM> may be made of a light guide material to transmit the illumination light emitted by the light source system <NUM> to inside of the oral cavity to achieve illumination.

A light guide channel <NUM> is disposed on the dental floss <NUM>. The light guide channel <NUM> may also be designed on the dental floss <NUM> to achieve transmission of the illumination light. The applicant herein only specifies the foregoing two ways of transmitting the illumination light. In actual application, those skilled in the art may design other ways of transmitting various light as required without departing from the protection scope of this application.
