Not OEM size, but totally OK with that!
To clarify my title, there appears to be several types of Sonic Care for kids toothbrushes out there. We have 2 recent 2019 ones and the heads are pretty much the same size as adult standard ones.<br /><br />NOW there are OTHER Sonic Care for Kids that DO have the tiny heads like THIS one. I am just noting that the 2019 Sonic Care for Kids toothbrushes we have (exactly as labelled on the box) already have much larger heads like the adults do.<br /><br />These replacement heads are the smaller ones and we are totally GOOD with that because both kids are under age 8 and we do feel this gets the job done better for them because the heads are smaller and of course they have small mouths, though they are quite loud. :--P<br /><br />The bottom of this fits their 2019 Sonic Care for Kids labelled toothbrushes and the same design I know will fit my Diamond Sonic Care adult toothbrush as well, if I really wanted to use it, just FYI.<br /><br />These heads are about half the size of an adult replacement head.
