In order to prevent shaft portion from being broken in ejection of base portion from mold, method for manufacturing interdental cleaning tool includes: base portion forming step of forming base portion by filling first space of primary mold (50) with synthetic resin, which includes first and second mold members (50A, 50B); and cleaning portion forming step of forming cleaning portion around shaft portion by filling second space of secondary mold with elastomer. Base portion forming step uses first and second mold members (50A, 50B). First and second molds include: first and second contact surfaces (51A, 51B); pair of first and second spaced-apart portions (54A, 54B); and first and second connection portions (52A, 52B), angle (θ) between each of first and second spaced-apart portions (54A, 54B) and separation plane being acute.

To provide a method for manufacturing an interdental cleaning tool that can prevent deformation of a core base at molding of a cleaning flexible part using an elastomer material, thereby effectively preventing occurrence of molding failure of the cleaning flexible part. The method in the present invention includes: a base part molding step of providing first metal molds 30 and 31 for molding base parts with a plurality of first molding spaces 32 aligned in parallel and including core base molding sections 32a and handle base molding sections 32b, providing the first metal molds 30 and 31 with connection part molding sections 35 to communicate with the adjacent handle base molding sections 32b, and supplying a synthetic resin material with a fiber material at a time to the plurality of first molding spaces 32 from gates 34 to form a plurality of base parts at a time; and a flexible part molding step of setting the core bases of the base parts into second metal molds, holding the core bases at two or more longitudinal portions by a plurality of pairs of hold pins in the second metal molds, each pair including two pins, and charging an elastomer material into the cleaning flexible part molding spaces.

An oral cleaning system for communicating a status of a handheld oral cleaning device (10) to a docking station (100). The handheld oral cleaning device includes a controller (70) configured to generate a unique charging cycle for each of a plurality of different charging states. The docking station (100) is configured to receive the handheld oral cleaning device, and includes a secondary charging induction coil configured to detect the unique charging cycle for each of the plurality of different charging periods. The docking station further includes a visual indicator (120) configured to indicate, based on the detected charging cycle, one of the plurality of different charging states of the handheld oral cleaning device.

In an interdental cleaning tool, a flexible cleaning portion including a core covering portion that covers a core base, and a plurality of recesses that are formed due to hold pins during insert molding. The recesses are formed along a longitudinal direction of the core base portion. A core base exposed portion of each recess has a shape elongated in an oblique direction that intersects both the longitudinal direction and a lateral direction orthogonal to the longitudinal direction, and, at a position where a dimension of the core base exposed portion in the longitudinal direction is maximum, the maximum dimension is 0.25 mm or less.

A hybrid dental tool is disclosed herein. The hybrid dental tool includes a flossing head and a handle portion. The flossing head can include a filament stretching between the leading arm and a trailing arm. The flossing head can be connected to the handle portion. The handle portion can include features that can receive and retain a pick. The pick can be a soft pick or a hard pick. The handle portion can further include an integrated pick that can be located at a free end of the handle portion.

A fluid emitting dental pick device for cleaning is having a handle defined by a body having an interior cavity. A pick component engaged to one end of the body bifurcates a pressurized fluid stream into two individual fluid streams projecting in opposing directions to clean both sides of the teeth concurrently. An optional reservoir holding a secondary fluid can also be employed which mixes fluid from the reservoir into the pressurized fluid stream which is delivered to the teeth with the two individual fluid streams.
