My 3 year old has very bad black SDF staining on his front teeth from when SDF was applied around a year ago. I recently came across Riva Star, which is apparently a 2 step SDF system that typically does not cause staining. Since his teeth are already black from SDF, is it too late to use Riva Star to reverse the staining?
