Abstract
An interdental brush has a hard body, an encapsulation layer and a plurality of soft and elastic bristles. The hard body takes a straight form and has a grip portion and a slender bristle portion. The hard body is sheathed by a soft and elastic material to form the encapsulation layer by means of insert molding. A grip is formed by sheathing the grip portion with the encapsulation layer to enhance holding comfort. The plural elastic bristles aligned in a radial fashion are formed on a surface of the encapsulation layer corresponding to the bristle portion. Given the foregoing interdental brush structure, the elastic bristles on the bristle portion can be deeply slid in between teeth for cleaning. The soft and elastic nature of the bristles ensures gums are not injured during cleaning.
