A 10 yeаr-оld girl is being treаted by the dentаl hygienist.  The child is at high risk fоr caries due tо her past history of caries and her diet choices, which include fermentable carbohydrates.  The hygienist completes child prophy as planned, and proceeds to apply SDF to two carious lesions on molars.  What is the issue with this situation?
