Yes, there is. There are two wrong ways to floss: not being thorough, and being too aggressive. When you floss, you’re supposed to concentrate on the lower portion of the tooth by the gum line and gently clean every side and between your teeth. Failing to do this can leave plaque which can harden into tartar and calculus. However, flossing is supposed to be gentle and you shouldn’t be using excessive force to clean between or around teeth. Being too aggressive can damage your gums and lead to inflammation or bleeding. Some choose to use water flossers or an oral irrigator for this reason.
