Oh, yeah! You heard it right. But that's okay, because you are not alone. Before I did my research, even I was doing the same. Well, It would be so injustice with your health if I didn't tell you about it. So here you go, let me reveal the secret of brushing your teeth in the perfect way and increasing their life by a huge margin.
Always use a good quality brush.
The cheapness or cost doesn't define the quality of a brush, always select ADA-approved brush which are perfectly fresh. Keep changing brush within months.
