What is the diameter range for medium toothbrush bristles?

Bristle diameter determines how stiff a toothbrush feels and how much abrasion it can cause. Medium bristles sit between soft and hard, offering a balance between effective cleaning and gentleness to gums and enamel. The range about 0.23 to 0.29 mm captures this middle ground: it is larger than typical soft bristles but not as large as hard bristles, providing enough rigidity to disrupt plaque while minimizing tissue irritation. The other ranges either fall into the soft category or extend into hard-bristle territory, so they don’t represent the standard middle range.
