In another thread we are currently discussing if it was safe make a cup

However what about brushing your teeth? Most people would brush their
teeth using water from the cold tap in the bathroom.

Maybe, jus maybe, water from the hot tap in the bathroom is safer than
from the cold? The following post in the original thread started off
my line of thinking:



Legionella is endemic in all water supplies at below 60C, (HSE Leaflet)

Legionella thrives (grows) at between 20C & 50C (HSE L8 Code of
Practice)

Do a google search on Legionella and then see if you want to clean your
teeth in water that has stood around for some time.
