breath care

i wonder the people that have kissing custom take care of own breath so much.
especial , oral care , for example breath care and teeth care and so on.
i used to see children had the bridge over their teeth on tv in US .
maybe in the countries of having kiss behavior , the oral care is one of the most important things i think. because if their breath are bad smell , when you kiss them your feeling is going to hell. hehehe.

in japan ordinary we have no kiss. so we don't pay　attention extremely.
but when i speak to them, there are some with bad smell breath.
recently young generations do take care of breath. their breath is fresh.
bad is older. specially same age as me. hahahahaha
so i want to take care of oral care without saying you are bad breath.
