The right interdental brush size seems to vary by gap
For crowded teeth, how do you decide when a narrow interdental brush is too large for a particular space, rather than just a snug fit? I’m also curious how to tell the difference between floss that’s awkward to thread and floss that’s cutting into the gum when it passes the contact.
Do people use a threader in some tight spots and a brush in roomier ones, or is it better to stick with the method your dentist or hygienist recommends? If neither tool passes gently, what’s the best next step to get advice on fit without forcing it?

“Snug” shouldn’t mean having to push: an interdental brush should enter with light pressure. If the wire bends, the bristles get sharply compressed, or insertion hurts, stop rather than force it; the brush may be too large or the space may not suit a brush. Floss can be awkward to thread through a tight contact, but it shouldn’t be snapped into the gum. If it hurts or you can’t pass either tool gently, ask a dentist or hygienist to check the fit and show you a suitable option.
