D/Sense Crystal is a one-step, dual-action desensitizer gel and cavity liner that is fast-acting and long-lasting. Calcium oxalate and potassium nitrate crystals penetrate deeply to occlude the tubules and seal the dentin surface with a continuous, acid-resistant complex (typically less than 3 microns thick). • Syringe delivery with SofNeedle™ foam-tip provides accurate placement and burnishing with no dripping onto soft tissue • Provides fast desensitizing with deep, long-lasting crystal formation • Occludes dentinal tubules with calcium oxalate and potassium nitrate
