FlexTab™ Flexible Clearance Tabs make checking the clearance of occlusal and interproximal tooth preps easy and accurate. Each disposable tab works like a feeler gauge to check clearance dimension. If tab pulls smoothly between a prep and opposing or adjacent tooth, the clearance is confirmed. Resistance means less clearance. Color-coded tabs available in three thicknesses: 1.0mm (pink), 1.5mm (green), 2.0mm (blue). 30 individually wrapped tabs per box.
