Eucryl Toothpowder - Freshmint ~ Stain Removal. Eucryl Toothpowder can be used to remove stains 2 to 3 times a week.. You should continue to brush your teeth twice a day for 2 minutes as normal using your usual toothpaste.. Simply wet your toothbrush, shake off surplus water and press the brush into the powder so you get a fine coating on the bristles - then brush your teeth the way your dentist recommends.. The fine powder texture lifts stains and discolouration from the teeth and leaves them feeling really smooth and clean.
