Proxabrush sizes range from ultra-fine for extremely tight embrasures to medium for moderate gaps. For example, effective filament diameters reported include about 0.7 mm for very tight contacts and about 1.1 mm for more moderate spaces.
Bristles are typically ultra-fine filaments or nylon. The core is a flexible wire, often nylon-coated or made from surgical-grade wire, combining flexibility with gentle cleaning action.
Package sizes vary from small clinical sets to consumer packs. Examples include clinical packs of five brushes, 10-count consumer packs, and larger quantities such as 40 brushes.
Many proxabrushes use color-coded systems for quick size identification, and some clinical sets are designed for chairside sizing so practitioners can match a patient’s embrasure size during instruction.
Gentleness comes from ultra-fine or soft filaments, flexible wire cores, and designs that permit atraumatic insertion into narrow embrasures to minimize gum irritation.
Proxabrushes can provide deeper cleaning between teeth by removing plaque and food particles from tight spaces and areas floss may miss. They are often easier for some users to handle and can be readily integrated into daily oral care routines.
