The Novashine Teeth Whitening Kit comes with two syringes of whitening gel but what happens if you run out? Don’t worry! The LED mouthpiece is reusable which means you don’t need to buy a whole kit again. Instead we offer refills of the teeth whitening gel here at Novashine! Our teeth whitening gels come in the original mint flavor, as well as a limited edition strawberry flavor. Shop for your refills below!
