Most people who complain that natural products like baking soda and salt are too abrasive to the teeth enamel aren’t using the correct toothbrush. The ultra-soft Feather-Like Bristle Toothbrush is gentler on the enamel than most “soft” toothbrushes, which reduces scrubbing trauma to the teeth or gums. Further, this natural BPA-free biodegradable bamboo toothbrush has ultra-fine bristles designed to reach tight spaces in between the teeth for more efficient plaque and bacterial removal.
