FAQ
Won't a hard bristle brush damage my enamel and gums?
Hard bristles remove stubborn stain, but the real risk with firm brushes is over-pressure, not the bristle itself. Kraft's Flexi-Nacken neck flexes to dampen the force you apply, so you get the scrubbing power without driving it into enamel or gum tissue.
Is Kraft right for me, or should I get a softer brush?
Kraft is built for smokers and anyone fighting heavy stain and tenacious buildup. If your gums are sensitive, recede, or bleed easily, choose SENSITIV instead — the firm bristle isn't the right tool for fragile tissue.
How does the Flexi-Nacken neck actually work?
It's a pressure-dampening flex point in the neck of the handle. When you press too hard, the neck bends and absorbs the excess force rather than transmitting it to the bristle tips, which is what usually causes brushing abrasion.
How should I brush to get the most out of it without overdoing it?
Brush twice daily and let the hard bristles and your toothpaste do the work — don't scrub harder to speed up stain removal. Guide the brush gently; if you feel the Flexi-Nacken neck flexing, that's the cue you're already at the pressure limit.
