My gaps are small. My dentist says my teeth are tight. I have found that using Glide is the best floss. Even with that I have at times cut right through the floss with a particular pair of teeth. You might want to try Glide.

I floss daily and sometimes twice a day. I keep floss at my desk at work and some mouthwash to kill some of germs that get stirred up. It is easy to fit that in when thinking through a problem.

I also take vitamin C twice a day. My dentists always comment on the good health of my gums and say "you take vitamin c don't you?" At 62 I want to maintain my gum and teeth health.
