EKULF pH professional 0,5 mm interdental toothbrush is a good medium size and fits you with smaller to medium large gaps between your teeth. EKULF pH professional is developed according to the Swedish pharmacies color-coding for interdental toothbrushes to make it easy to recognize your specific color and size. The series maintains the same high quality as EKULF pH with 400-1000 small and delicate bristles and has a stainless, plastic-encased wire that protects your teeth. Each packaging is delivered with a protective cap and a grip-enlarger. An interdental toothbrush should never be forced in between the teeth, but rather glide easily.
