What causes bad breath in teenage girls?

Bad breath itself is not a disease, it is caused by a variety of factors. Such as systemic diseases (stomach disease, liver disease, diabetes, etc.) or vitamin B6, trace element zinc deficiency, most of the bad breath is the cause of local oral diseases, especially in adolescent girls.

This is due to the close relationship between female ovarian function and oral mucosal epithelium, when the ovarian hormone secretion is normal, the oral mucosal epithelium becomes healthy and firm, the secretion function of the salivary gland is vigorous, the activity of salivary lytic enzyme increases, the antibacterial effect is strong, and the disease resistance of the mucosa increases.

If the secretion of ovarian hormones decreases, the secretion function of the salivary glands decreases, the amount of saliva secretion decreases, the activity of salivary lysozyme is weakened, the pathogenic bacteria in the oral cavity increase, the saliva becomes sticky and smelly, and the self-cleaning effect of the oral cavity is weakened;

Adolescent girls are often prone to infection of the oral mucosa and periodontal tissues resulting in bad breath due to their periodic instability of gonadal activity, large fluctuations in sex hormone levels, and a love of snacks and lack of attention to oral hygiene. But this kind of bad breath is mostly transient, so there is no need to worry about it.

In addition, some systemic diseases such as gastric Helicobacter pylori infection can also cause persistent halitosis, which is often accompanied by varying degrees of hunger and stomach pain, and with the eradication of Helicobacter pylori, the halitosis also disappears.
