My wife bought new toothbrush heads on her way home from work today.
They didn’t fit. She bought the “Oral B IO” heads, but we have a “regular” Oral B toothbrush, not the Shiny Fancy IO design.
And this is after she bought replacement heads last week at another store – which turned out to be “compatible for” a different brand :(
Ugh.
Not really that much difference if you brush correctly
actually there is a huge difference, studies shown that electric both sonic and rotating heads are superior to manual brushing. and plus people brush too hard with manual ones, the electric ones have sensors for pressure, often time they dont brush long enough as well with manul ones.
Or have Parkinson’s.
