Sunstar Butler GUM Proxabrush Go-Betweens Refills, Tight is used for removing plaque and food debris from narrow interdental spaces and around fixed dental appliances. The Tight tapered brush profile is designed for confined embrasures where a broader interdental cleaner may not fit comfortably, and the triangular bristles increase contact with proximal tooth surfaces, helping patients clean areas that routine toothbrushing may miss around natural teeth, crowns, bridges, implants, or orthodontic components. Each package contains 18 packs of 2 refill brushes each, totaling 36 replacement heads, designed for use with compatible GUM permanent or dual-ended handles rather than as a standalone brush.

The refills feature a nylon-coated wire core and antibacterial bristle treatment, supporting careful contact around restorations and implant components without exposed wire rubbing directly against the surface. Practices ordering interdental refills from a dental supplier typically keep the Tight size stocked separately from Moderate and Wide refills to match patients with narrower embrasure spacing. The refill works by attaching to a compatible handle, letting the user guide the brush through an appropriately sized interdental space with gentle back-and-forth movement to disrupt plaque along proximal surfaces and appliance contours. Sunstar states that the triangular bristle geometry removes up to 25% more plaque than conventional round bristles under its referenced testing.

The nylon-coated wire adds flexibility and helps reduce scratching or galvanic sensitivity around dental devices, and the antibacterial treatment helps protect the bristles between uses when the refill is rinsed and replaced as directed.
