Premium Interproximal Brushes are made with durable Dupont® nylon bristles and stainless steel stem wire. The brushes are tapered and graduated in sizes (C, S, A, B, D and E) from 1/8 inch to 5/8 inch in diameter. The two largest brushes (D and E) are for spaces where a tooth or several teeth have been lost, leaving the adjacent proximal surfaces very difficult to clean with a traditional brush. Made in the USA.
