Bad breath can be reduced
by using hydrogen peroxide combined with yoghurt
containing active bacterial culture. Hydrogen peroxide
at a concentration of 1.5% can be taken as an oral
antiseptic by gargling 10 ml, about two teaspoons.
Hydrogen peroxide is commonly available at a concentration
of 3% and should be diluted to 1.5% by mixing it
with an equal volume of water. Hydrogen peroxide
is a powerful oxidizer which kills most bacteria,
including useful
aerobic bacteria. Unless yoghurt is eaten or aerobic
bacteria is added by some other means, foul smelling
bacteria will eventually reproduce, so on its own
the effects of hydrogen peroxide are temporary.
Yoghurt with active bacterial culture contains beneficial
aerobic bacteria, which does not have a bad odor.
This bacteria helps digestion and by occupying the
host, prevents other bacteria from returning. So
eating yoghurt colonizes the host with good bacteria,
especially after most of the previous bacteria were
killed by hydrogen peroxide. This combination displaces
odor causing bacteria for a long time.
