Having wisdom teeth does not necessarily cause bad breath. However, they can cause bad breath if they are not cleaned properly, if there is caries, pericoronitis, or if they cause food impaction.
1. Wisdom teeth are the last big teeth of human beings. If they erupt properly and you are able to brush and floss them every day, they generally do not cause bad breath.
2. However, most wisdom teeth are blocked, difficult to fully erupt, and the surface of the gums are prone to form blind pockets, which retain food debris and can cause bad breath. Wisdom teeth are not cleaned properly and caries occurs, and a large amount of bacteria will remain in the cavities. Or wisdom teeth and neighboring teeth are prone to food impaction, all of which can cause bad breath.
It is recommended to consult a medical professional.
