Cotisen Prophy Brushes (Pack Of 100) Prophy brushes provide a superior clean and polish to standard prophy cups because they flare and reach under the gum line and into the developmental grooves. The brushes are recyclable so please save used brushes to help us care for the environment. The latex-free nylon bristles on the brushes are gentler on gums and more flexible. The flexibility of the bristles allows easier access subgingivally to remove debris from pockets, as well as occlusal fissures and grooves, without harsh scraping or damage. Cotisen prophy brushes are designed to be used with natural pumice, avoiding the use of chemically loaded prophy pastes. Cotisen prophy brushes are also excellent for polishing composite restorations.
