Toothbrush heads with wear indicator for toothbrush

Head wear indicator

— there's a unique indicator that notifies users when it's time to replace their nozzle. Typically, this is achieved by incorporating certain fibers that are colored in a specific way, gradually fading over time. This fading helps users assess the condition of the nozzle, reminding them of the importance of regular replacement for toothbrushes or electric toothbrush heads.
