HygieneEdge shares a video of using ReLeaf, and says, "HybenX, or Desiccation Shock Technology, is specifically designed to target diseased tissues. With that, if you accidentally get some on healthy tissues, don’t panic. Normal gingiva resists the instant desiccation process. Incidental contact with the gingiva will cause a blanched (whitened) appearance of the superficial surface (simply dehydrated tissues - NOT a burn) and will rehydrate in a few days with contact to water and saliva. Simply wipe or use water to remove and know that if it’s touching/placed on diseased epithelial tissues or biofilm, that’s where it specifically works its magic."
