PROBLEM TO BE SOLVED: To provide a gum massage brush capable of fully massaging gums, even small sites thereof, without damaging the gums.SOLUTION: The gum massage brush comprises a brush part that can disperse force applied to the gums over the whole brush part to prevent the gums from being damaged by any of features including: a feature in which a length of a brush fixing part is not longer than seven-tenths of that of a brush base part; a feature in which a hardness of a whole brush support part is similar to that of the brush base part; a feature in which a low resilient elastic material other than a material constituting the support part is embedded in a neck part such that a hardness of the brush fixing part is similar to or less than that of the brush base part; and a feature in which a thickness of the brush fixing part is thinned regardless of the hardness thereof. The brush with such a configuration enables tips of protrusion bristles to be sharpened such that the small sites of the gums can be massaged. |
