The flexibility of the head makes it very easy to get the back of the back molars! 6 Stars
*** update 8/5/2020  I just realized that the way it bends that it makes it very easy to brush the BACK of the farthest molars.  I hadnt thought about brushing that surface until my dentist removed a molar because of it.<br />So remember to get the back of your back molars always.  This makes that Very easy (6 stars)<br />It takes a bit of getting used to and I originally thought the bristles were too short.  But with how soft the bristles are if they were longer the ends of the bristles would not move against your teeth.  The bristles in this case grips the stuff between your teeth and pulls it out instead of scraping it out of your teeth.<br />It takes a bit more work it seems to do a thorough job like all soft bristles.<br />Another advantage with this one is that because there are such gaps between the bristles its easy to clean after every brushing.  I mean a FULL clean.  Just your thumb and running water is all it takes.  Give it a little buzz to shake off that water and makes it easy to dry.<br />So  I would give it more of a 4.25 because of how much more work it takes to get all the gunk off your teeth.  Other than that it would definitely be good for teething children or anyone with sensitive gums.
