Edm 39 Draw your toothbrush

Every time I go to the dentist, I notice how hard the dental assistant uses that iron pick to scape plaque off my teeth, and every time she tells me I don't have much plaque build up and sounds disappointed. However, I notice the dentist advises the use of soft to medium toothbrushes (I use hard). I think they tell you to use a soft toothbrush because that enables a larger degree of plaque build up which in turn requires 6 month visits and finally cavities. If they are so concerned about saving the enamel on your teeth then why do they use that pick that definitely scrapes of not only plaque but enamel. wc + acrylic white +blk pen
