EKULF pH professional 0,7 mm and EKULF pH professional 0,8 mm is the most common sizes of interdental toothbrushes in the Scandinavian countries and fits you with slightly larger 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.
