These silicone pieces are essential for wearing your Grillz. Without them, your Grillz wouldn't bond to your teeth.
After heating them and placing them in your Grills, you bite into them, to imprint the imprint of your teeth on them, and voila, you can now be sure that your Grillz will not come out of your mouth.
Our silicone is pure and purchased from recognized suppliers, so there is no need to worry about oral hygiene.
So, buying silicone in addition to that supplied with your jewelry is essential, if you plan to wear your teeth in Gold, Diamond or Silver. In fact, given that you systematically remove your accessories before eating, you risk easily losing your silicone, buying extra is good insurance.
