Is there bad breath when kissing?

Whether bad breath occurs during kissing mainly depends on both individuals' personal oral hygiene habits and their physical condition at that moment. Good oral hygiene practices, such as regular tooth brushing, flossing, and rinsing, can effectively reduce bacterial growth in the mouth and lower the risk of bad breath. If either partner has recently neglected oral cleaning, suffers from oral diseases (such as gingivitis, dental caries), or has consumed certain strongly odorous foods (like garlic or onions) without proper oral cleaning afterward, bad breath may occur during kissing. Therefore, to ensure fresh and pleasant kissing experiences, both partners are advised to maintain good oral hygiene, have regular dental checkups, and avoid consuming odor-causing foods before important occasions, or clean their mouths promptly if they do.
