Io3 vs io4?
Hello guys!
I have gum recession and my dentist suggested I should take the oral B io3.
The io4 has an extra mode called "super sensitive" and I was wondering if it would be an improvement for my sensitive gums?
Does anyone here have experience on these two models? Is there a meaningful difference in this extra mode?
