Rarely I think about it. But at times I wonder if we could have home gamma radiation machines to sterilise well about everything... From food to why not tooth brushes or other materials that don't handle heat or other options too well...
Sadly gamma radiation generators will never be safe enough to be widespread for that.
Still could it be workable?

Would washing toothbrush with soap just work?
I also have seen recommendations to microwave your toothbrush.
Heat and plastic as a combination always scares me, I'd probably avoid microwaving toothbrushes if I were you.
Any antibaterial would work
I never brush my teeth, I irrigate them a couple of times a day and use floss as needed.
That’s pretty rank. Do you spend a lot of time with people?
Didn’t mythbusters prove fecal matter on brand new toothbrushes, fresh out of the package?

I hate to say it, but... duh.
It's literally going in your mouth. And rinsing it with tap water isn't going to fix that.

Toothpaste basically has dish detergent in it which probably makes it not quite so bad.
TLDR; "I don't think most people are getting sick from their toothbrush," she says.
This is just germaphobe pornography. Your toothbrush is fine. You’re less healthy if everything is like a clean room in your life.

30 or more years ago (?), Consumer Reports did a report on toothbrushes and they did a follow-up note or article clarifying their recommendation of how often to change toothbrushes. Their recommendation was not because of bacteria as many readers apparently thought, but because the bristles get worn down and don't clean as effectively.
And the "toilet plume"? Is that more of a problem in Britain? Looking back at John Postgate's Microbes and Man (which I read back in the 1990s):
(That was written back in the 1990s or earlier; British folks and travelers can obviously provide more current insight than me, who has never traveled outside the U.S.!)
