The present invention relates to a dental mouth mirror, and more particularly to a dental mouthpiece for use in dentistry and for providing a dentist with a condition or condition of a patient in a patient.

In general, whether it is dental surgery or dental examination, there is a cooling liquid (usually water) required for saliva, saliva, or drilling in the oral cavity of a dental patient; usually, in order to facilitate the dentist to check the mouth, For dental or dental surgery, these extra saliva, saliva, and coolant must be sucked out and sucked out by a dental machine or tool to prevent the liquid from blocking the work of the dentist or dental assistant.

As shown in Figure 1, during the dental treatment process, such as the filling of the molars, the cleaning of the teeth, and the dentist's other treatment of the patient's teeth, it usually relies on a drilling equipment 7 and a dental mirror. The drilling device 7 can remove dental calculus, perform alveolar bone drilling or perform dental surgery, and the mouth mirror 8 can move and rotate in the oral cavity M, so that the dentist or dental assistant can pass through the oral mirror 8 The condition in the patient's mouth M was observed. Here, the mouth mirror 8 is used to keep the patient's tongue and cheeks away from the processed teeth while reflecting the outside light in the process. The area is well provided to the dentist for a good view of the treatment area. The specular reflection of the mouthpiece 8 can help the dentist observe the oral tissue that cannot be seen through direct vision.

In addition, because of the dental examination and dental treatment, the patient will produce saliva; or, when performing dental surgery or alveolar bone drilling, the water will be used to cool the drilled alveolar bone. Therefore, it will pass through. A suction device 9 absorbs the flushing liquid sprayed by the drilling device 7, the patient's saliva, and tooth debris.
