I am often asked why some people get bad breath and not others. This is an interesting question.
When we are born, our oral bacteria makeup is passed onto us from our parents. This often happens with the first touches or kisses. This was shown in a study at Queensland University on premature babies who did not get mouth bacteria until they had human contact after leaving their incubators.
These bacteria colonised at birth, are now our bacteria for life. we can modify them for the worse by taking antibiotics, disinfectant mouthwash and lifestyle habits. Or we can modify them for the better by cleaning away the excess bacteria made and pumping the mouth full of good probiotics such as K12 and M18. These KForce probiotics have mountains of research from Otago University as to their many health benefits.
Bad Breath is a bacterial problem in 95% of all cases. So if your parents gave you bacteria that like to break down proteins and bad breath smells, and then you feed these bacteria without cleaning the food sources and excess bacteria away twice a day, then you will get Bad Breath.
Your compatriot that is low in these bad breath bacteria, is more lucky. They do not need the strenuous oral hygiene measures that you do, as they are not making as many bad breath bacteria and gases.
But do not worry, low levels of cleaning in these "lucky" people will lead to other mouth complaints eventually such as gum disease and an increase in pathogenic illnesses. There is no substitute to a balanced bacterial mouth.
