No, POVIDONE-IODINE (BETADINE®) Gargle does not stain the teeth. The natural brown colour is due to Povidone-Iodine, the active ingredient of POVIDONE-IODINE (BETADINE®) Gargle. The product retains the germ killing effect of iodine but unlike iodine, it is generally non-staining3.
POVIDONE-IODINE (BETADINE®) preparations do not stain the skin, fingernails, hair, or natural fibre either.3 If you accidentally get POVIDONE-IODINE (BETADINE®) on natural fibres it can usually be easily washed off with water and soap. For man-made fibres, POVIDONE-IODINE (BETADINE®) can usually be washed off with the help of a stain remover.
