⟩ What is the mean of "no room to floss"?
No matter how tight the fit, there should always be room for floss between your teeth. If not, you may need to switch to a thinner floss or a waxed one. You can also try a different kind of tool, such as a looped flosser or a dental pick. Experiment until you find a product that works for you, and then use it every day. Flossing is a must for good dental health.
