2. You’re brushing too hard if your gums start to recede.
Each and every one of our teeth are protected by enamel, which can be severely harmed by over-brushing. And by harming enamel, our gums may start to recede, exposing the roots of our teeth to great danger. If your teeth reach that point, you might need to add fillings, root canals, or even extract teeth that are no longer healthy. According to dentists, about 10%-20% of the population around the world has damaged their gums due to over-brushing.
