Xero Picks Wellness toothpicks excite dull dry mouths while delivering added supplements for a boost. We use a patented technology to infuse these toothpicks with supplements, xylitol, sucralose, flavors and jambú, a concentrated extract of spilanthes acmella. Jambú has strong saliva-inducing effects and is responsible for the tingling sensation in the mouth and lips often experienced during salivation. Recommended Use: Suck and flip. Lightly imprint teeth once wood has softened to release more ingredients. Suggested 20-25 minutes for maximum use. Use and discard. Do not swallow. To open tube – simply squeeze both sides of tube to pop the top. These tubes are child resistant by design.
