Proxa interdental brush heads are offered in ultra-fine diameters for very tight embrasures (about 0.7 mm) and slightly larger ultra-fine heads for medium-sized embrasures (about 1.1 mm). Listings describe spacing using terms from "extremely tight" up to "medium/moderate."
Head types include extra-soft conical heads with plastic-coated wire for implants and prosthetics; ultra-fine tapered heads for braces and tight spaces; and angled/holder kits combining ultra-fine brushes with a specialized angled holder for orthodontic access.
Proxa offers compact pocket or travel sets with a case or travel caps. Listings call out trial/mini/travel sizing and breathable travel caps that allow multiple days of use.
For orthodontic care, listings emphasize ultra-fine tapered heads that fit under wires and between brackets, reinforced or angled holders for reach, and designs that reduce irritation around appliances.
Listings mention surgical-grade wire cores for flexibility and precision, plastic-coated wire cores to protect implants and restorations, and nylon-coated wire on some reusable picks.
