To open the Snow Original Wired Kit wand (which seems to be what's being referred to as the "mouthpiece"), you'll need to twist it. According to the YouTube tutorial, it might take a few twists or clicks the first time to get it open. This is normal. Once the serum appears at the tip, you can apply it to your teeth as if you're painting them.
In short, here's the process:
- Grip the wand. Hold the Snow Original Wired Kit wand firmly.
- Twist the wand. Twist the wand until you feel a click or see the serum appearing at the tip. It may take a few tries initially.
- Apply the serum. Once the serum is visible, you can apply it to your teeth.
