FlexiStrips dental polishing strips will help you put a high polish on interproximal areas while decreasing the tenacity of interproximal stains. FlexiStrips come in both regular and narrow widths to give dentists greater flexibility in interproximal finishing and polishing. Wide dental interproximal strips are excellent for the incisal 2/3 of the interproximal, whereas narrow interproximal finishing strips can be used to polish the gingival aspects of the interproximal without damaging the tissue.
