Review on GUM Proxabrush Permanent Handle with Tight, Moderate, and Wide Go-Betweens Heads - Pack of 6 by Natasha Graham

Really wanted to use this but neither head fit for me. I ordered this instead of the others because it comes in 3 sizes so you can work out which one fits you best, but even the "slim" size didn't fit me. It has a metal wire with bristles, which I didn't like. Because the "narrow" size was too big, the metal wire pierced my gums, causing my gums to bleed and hurt. The wire is good for its strength, unlike some other models that are made of a softer material that bends too easily. A smaller size for very dense teeth and maybe using something to cover the metal like gum safety clips do would do the job for me.
