What’s the difference between the 3-row and 4-row BrushEco?

Currently, both the 3-row version and the 4-row version are adult size. Both brushes can be used on any surface in the mouth, but the different bristle spacing does make each one a little more handy for certain functions.

The 3-row version has bristle tufts that are more spaced out, so they’re really great for doing the Bass Brushing Technique along your gum line.
