I used to get this for my brothers retainer and I would soak it during the day with one of these tablets and him being the germaphob that he was, could feel ok about putting his retainer back in, knowing the tablets cleaned it completely. And it left it tasting minty fresh. You cannot beat the price.
Denture tablets can also be used for brightening and removing staining from hard to remove nail polish stains! Just dissolve the tablet in warm water and soak your fingertips before gently scrubbing with a nail brush.
