No, BETADINE® Gargle does not stain the teeth. The natural brown colour is due to povidone-iodine, the active ingredient of BETADINE® Gargle. The product retains the germ killing effect of iodine but unlike iodine, it is generally non-staining3.
BETADINE® Gargle preparations do not stain the skin, fingernails, hair, or natural fibre either.3 If you accidentally get BETADINE® Gargle shed off with the help of a stain remover.
CAUTION: Immediately remove spills from plastic floors.
