In oral care device manufacturing, bristle splay is often dismissed as a natural sign of toothbrush wear. However, uncontrolled bristle splaying could directly contribute to gum recession, leading to long-term oral health complications. Is ignoring premature bristle deformation a form of manufacturer negligence? Let’s explore how poor brush head design exacerbates gum damage and what solutions can prevent it. What Is Bristle Splay and Why Does It Matter? Bristle splay occurs when toothbrush filaments bend outward or lose their alignment after repeated use. While all bristles deteriorate over time, rapid splaying results from: Inferior filament material lacking fatigue resistance Poor bristle end-rounding, increasing localized stress Improper tufting angles or filament length mismatches Excessive brush head pressure or inadequate stiffness control When splayed, bristles no longer clean effectively. Worse, their sharp or angled tips can abrade gum tissue, triggering damage. Understanding Gum Recession: The Hidden Risk Gum recession is the progressive exposure of tooth roots due to gum tissue erosion. It can be accelerated by: Mechanical abrasion from aggressive brushing or misaligned bristles Chronic inflammation aggravated by residual plaque due to ineffective cleaning Overstimulation of gingival tissues from filament microtrauma Splayed bristles not only fail to remove plaque effectively but also…
