*I’m not a doctor or your doctor*

The concern isn’t that brushing too hard will hurt your teeth themselves but rather damage your gums. Gum damage can accumulate and progress to inflammation and even recession of your gums away from your teeth. Just like a tree needs soil, without your gums you teeth will more easily get damaged or diseased and that’s No Bueno.
