Majority of tooth brushes patients bring resemble this toothbrush. The frayed bristles are quite injurious to gums and teeth.
Once the patients are made aware the injurious effects of such a toothbrush, they get motivated to take care of toothbrush. Normally, the brush bristles start curling outwards (“fraying”) after about 3 months. That’s the time to change the toothbrush.
There are two cases which need special mention. Once a person who was suffering from ‘pyorrhoea’, he brought a baby brush as he thought that brushing with a baby brush would be gentle for his teeth. He was motivated to use a proper adult toothbrush.
Many years ago i came across a family who were using a single brush –all of them using the same brush in the morning.
