Preventech’s Vella® 5% sodium fluoride varnish with Xylitol eliminates lumps and clumps, delivers a faster thin-layer application and dries clear. Vella is ideal for hypersensitivity and cases involving children who don’t like the fluoride tray technique. With twice as many bristles, Vella’s 2.0 ultra brush applies more product faster. Vella’s container is extremely sturdy. You can hold it closer to the mouth and wipe the brush tip more easily. That translates into fewer trips to the well, ensuring a faster, less messy, thin-layer application. Like all Preventech products, Vella is backed by a 100% satisfaction guarantee.
