Dry mouth is one of those problems that sounds minor until you’re living with it. It affects speech, swallowing, and oral health, and it’s often a side effect of medications or a symptom of conditions like Sjögren’s syndrome. GRETHER’S Blackcurrant Pastilles are one of several products aimed at this market, and the refill bag format is a sensible, no-frills approach. Here’s a closer look at what they offer and where they fall short.
The pastilles come in a 3.7-ounce refill bag, which is essentially a resealable pouch designed to top up a smaller, more portable tin or container. That’s a practical design if you already own a Grether’s tin or another small container, but it’s less convenient if you’re starting from scratch—you’ll need to transfer them to something pocketable. The bag itself isn’t sturdy enough for daily carry; it’s meant for storage at home or in a desk drawer.
Functionally, these are hard pastilles, not soft chews or gum. They’re sweetened with maltitol and contain blackcurrant juice concentrate, which gives them a tart, fruity flavor. The texture is firm and long-lasting—each pastille takes a while to dissolve, which is helpful for dry mouth because it stimulates saliva flow gradually. However, they’re not a quick fix; you can’t chew them without risking dental work, and they don’t provide instant relief the way a spray or a sip of water might.
In real-world use, these pastilles are best suited for situations where you need sustained moisture—during meetings, on long flights, or while reading in bed. They’re discreet enough to use in public, and the blackcurrant flavor is pleasant without being overpowering. That said, the sweetness from maltitol can become cloying if you use them frequently, and some users may find the tartness a bit sharp. Also, maltitol can have a laxative effect in larger quantities, so it’s worth moderating intake.
Compared to similar products, such as sugar-free gum or artificial saliva sprays, pastilles like these offer a middle ground. Gum is more socially acceptable in some settings and provides chewing stimulation, but it can be tiring for people with jaw issues. Sprays deliver immediate moisture but wear off quickly and can be awkward to use in conversation. Grether’s pastilles last longer than a spray but require more time to dissolve than gum. Another alternative is moisturizing mouthwash, which can be used as part of a routine but isn’t portable. Each has its place, and the pastilles are a solid choice for on-the-go relief that doesn’t require water.
One limitation is the packaging. The refill bag is not resealable in a way that keeps the pastilles fresh for months—once opened, they can become sticky if exposed to humidity. It’s best to transfer them to an airtight container. Also, the bag doesn’t include a carrying case, so you’ll need to supply your own if you want to take a few with you. That’s a minor inconvenience but worth noting.
Who are these suitable for? People with mild to moderate dry mouth who want a long-lasting, portable option that doesn’t require water. They’re also good for those who prefer a tart, fruity flavor over mint or artificial sweeteners. They’re not suitable for anyone with a sensitivity to maltitol or other sugar alcohols, or for those who need immediate, strong relief—in which case a spray or gel might be more appropriate. Also, if you have trouble with hard candies (e.g., dentures or swallowing difficulties), these may not be safe.
Overall, GRETHER’S Blackcurrant Pastilles are a practical, effective option for managing dry mouth, with a few trade-offs in packaging and formulation. They’re not a cure-all, but they fill a niche for sustained, discreet relief. The refill bag is a cost-effective way to stock up if you already use them regularly, but newcomers might want to try a smaller size first.
