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.


I genuinely don’t know, because every dentist I’ve ever had has recommended electric. There are studies as well. I’m not trying to say your teeth aren’t immaculate because I don’t know you, but for the average person electric toothbrushes are better, sincerely.
This is def the case for me. I used to bring the old fashioned toothbrushes for camping (well, for any travel). I noticed a HUGE difference when I’d get home again.
Now I just bring the normal toothbrush. The battery lasts long enough for most trips that it’s fine.
For camping, as you have the iO heads already, get a iO series 2 body as they use the older motor but new heads and the battery lasts about 20 days. Way longer than other iO series bodies. It’s not as good as those either but for camping, meh.
Also, you can buy USB-plugged oral B chargers. Useful for travel
I believe you, but I’m also interested in the studies, how much worth it it actually is.
Like, is it worth it because people in general have poor brushing technique and the electric brush “solves” this just by how it works, or is it better even with proper brushing technique with manual brush?
Those are some of the questions I have. 😁
Here’s just one of said studies. https://pmc.ncbi.nlm.nih.gov/articles/PMC3652371/
From that study:
LOL! I do not think that means what they thought it means. Kinda hard to keep the participants from knowing which study group they’re in.
Still, interesting setup. 60 dental students makes sure that the control group brushing manually is doing so with proper technique. They were getting the best-case scenario for manual brushing.
Can it not still be double blind if the participants don’t know precisely what is being measured or studied? For example, perhaps they know they are involved in a toothbrush study, but not that one group will have different brushes, or precisely what measurements are being taken.
No. Double blind means that both the researchers and the participants don’t know who is in which group (control group or experimental group). The idea is to avoid spoiling studies with the placebo effect.
It’s kind of hard to avoid knowing that you’re in the control group when you’re being asked to brush with an old-fashioned toothbrush instead of an electric one.
Decided to do some reading!
So double blind doesn’t have to mean the researchers or even the participants were blinded, just that two parties were.
In this specific study, I think it’s that the data analysts were not aware of which groups the data came from.
Huh, that doesn’t match my understanding (TBF I don’t work in the field).
Looking again at the study… Dr. Jain had a second person split the students into two groups. I’m not sure whether she conducted the followup exams or had yet another person do that. Assuming that the students were strict about not talking about which toothbrush they were using, I suppose you could call it a ‘blinded’ experiment. I don’t really see how you could double it, though.
