Clinical Study of Toothbrush Bristle Wear and Its Influence on the Ability to Remove Dental Plaque
The wear of the bristles significantly reduces the effectiveness of plaque cleaning, as we proved with a clinical study. Therefore, it is important to replace the toothbrush as soon as the bristles are moderately worn. In this way, we avoid an increased risk of hard dental plaque formation, caries, and inflammation of soft dental tissues.
The study showed that 3 main factors significantly reduce the effectiveness of the toothbrush:
- wear of the bristles
- bacteria
- limestone
Therefore, we advise users to have toothbrushes in stock so that not too much time elapses before the replacement, as this means a longer period of less effective cleaning.
