ABSTRACT:
The invention provides a suction tip for dental treatment which has no possibility of causing a patient discomfort such as pain when its end portion touches the gingiva or oral cavity mucosa of the patient, and enables an easy suction operation and an easy attachment operation to a suction tube by its secured entire strength. The suction tip for dental treatment has a cylindrical shape as a whole, a front end portion of the cylinder is cut obliquely, and a back end portion thereof is cut vertically, thereby forming a back end opening portion and a front end opening portion. A front end portion which is to touch the gingiva or oral cavity mucosa of a patient is made of soft silicone rubber, and a cylindrical base portion continuing to this front end portion is made of hard silicone rubber. The soft silicone rubber forming the front end portion is gel silicone rubber.
