Eaue oxygenee has a nice sound to it. In English, it's hydrogen peroxide,
a little harsher sounding. NaHCO3 is sodium bicarbonate, also known as
baking soda. You really want to post this to a dentistry group, not an
immunology group, because what you're probably most interested in is
whether you'll be damaging your teeth with this stuff. People have
brushed their teeth with baking soda for a long time, so I guess you're
mostly concerned about the peroxide? In limited quantities, it should be
fine; your body has an enzyme that detoxifies H2O2 to water and oxygen,
which is why foam appears when you disinfect a cut with peroxide.
