Zinc-Free Denture Adhesive Showdown: Waterproof, Extra Strong Hold? We've tested countless denture adhesives over the years, but this zinc-free formula truly stood out. The promise of a waterproof, extra strong hold felt too good to be true-until we applied it to our upper, lower, and partial dentures. The first-time use was a breeze, with no messy residue or lingering chemical smell. What surprised us most was how it maintained a firm grip through mealtime, even with our most stubborn snacks. The 1.4 oz size is practical, but we found ourselves needing more for heavy-duty days. Despite its strength, the product's gentle formulation was a relief, avoiding the irritation some zinc-based alternatives cause. While we're impressed by its durability and versatility, the price point might be a hurdle for those on a budget. Still, for reliable, irritation-free adhesion that works across all denture types, it's a solid contender. Would you trust it for daily use?
