Toothbrush under uv light

[Perpetual Motion]

If i put my toothbrush under a UV light to kill bacteria is it safe to put into my mouth?

I'm not sure I would put a UV light in my mouth... Just kidding, i can't see any reason it wouldn't be safe to use the tooth brush after it was irradiated with UV light or gamma rays for that matter...

Certainly safer than if you didn't. What is the concern?

The UV light probably won't kill many bacteria.

UV can be bactericidal in the shorter wavelengths IIRC.

The UV used for sterilisation is UV-C and is very dangerous to your eyes and skin when directly exposed to it so don't go and cobble together your own unit will you?...buy one made for the purpose.

 

Reading up on it in surgical situations, it can be used for maintaining instrument sterility after autoclaving so it seems to be a pretty good micro-organism inhibitor.

Many of the bugs will be hiding between the bristles of the brush.

The bristles are most probably nylon.

Nylon is opaque to hard UV.

The UV will not reach some of the bugs.

You do not have to worry about your toothbrush becoming radioactive after its exposure to UV if this was the gist of your question.

The irradiation of any electric toothbrush to UV light will probably kill your anticipation that bacteria can be alive and fancily radioactive!
