SmartMouth Dry Mouth refreshes, moisturizes, rehydrates, cleans, and soothes oral irritation while lubricating oral dryness. SmartMouth’s patented zinc ion technology also clears away bad breath, blocking its return for 12 hours per rinse. Thrill your tastebuds with our mint oral rinse to defeat mouthy odors, including garlic, coffee, and cigarette breath. Beating bad breath means dealing with the real source of bad breath—sulfur gas. If you are serious about dealing with bad breath, nothing works better than activated zinc ion technology. SmarthMouth’s dual formula combines a sulfur eliminator and a zinc ion activator to release billions of zinc ions. Activated SmarthMouth clears away existing sulfur gas and its new production of new sulfur gas for 12 hours. SmarthMouth is the only activated formula that deals with the real source of bad breath for a full 24 hours. This oral rinse is dentist recommended. For best results, use SmartMouth mouthwash in the morning for a full 12 hours of clean breath, and use it again before bed to prevent morning breath.

One "swish" in the morning and my mouth is fresh all day. Review: Great relief for dry mouth + fresh breath! - I’ve been dealing with dry mouth for a while and this mouthwash really helps keep my mouth feeling moist and comfortable throughout the day. The mint flavor is refreshing but not too strong, and there’s no burning sensation like with some alcohol-based rinses. I noticed a big improvement in my breath as well — it feels cleaner for hours after rinsing. The zinc-ion technology seems to do what it claims! The only downside is the dual-pour bottle design — you have to pour carefully to get both sides to come out evenly, and it can be finicky at first. But once you get the hang of it, it works fine and is worth the slightly higher price for the relief it gives. ## Features - RELIEVE DRY MOUTH & COTTONMOUTH - SmartMouth Dry Mouth Activated Oral Rinse provides relief from the symptoms and discomfort of dry mouth.

Only down side may give you a little dry mouth. But gum or a mint will help the dry mouth. ## Frequently Bought Together - SmartMouth Activated Dry Mouth Mouthwash, Dry Mouth and Bad Breath Relief, Mint, 16 fl oz, 3 Pack - SmartMouth Dry Mouth Dual-Action Mints - Sugar-Free Breath Mints - 50 Count, 3 Pack, Mellow Mint - SmartMouth Original Activated Mouthwash - Adult Mouthwash for Fresh Breath - Oral Rinse for 24-Hour Bad Breath Relief with Twice Daily Use - Fresh Mint Flavor - 0.4 Fl Oz (30 Travel Packs) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/389825306-dry-mouth-activated-rehydrating-mouthwash-16-fl-oz-each-3](https://www.desertcart.jp/products/389825306-dry-mouth-activated-rehydrating-mouthwash-16-fl-oz-each-3) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-25*
