In most cases, patients with toothache contain white wine without any effect. Generally, toothache is caused by caries, endodontic disease and periapical disease, which are caused by bacteria that have invaded the inside of the teeth, such as the deep layer of dentin, or the parts of the pulp and root tip, which have penetrated deep into the tooth. The alcohol applied by oral liquor only has a certain bactericidal effect in the mouth, but for the bacteria inside the teeth, it is not even touchable, so there is no possibility to kill the bacteria inside. Therefore, the toothache still needs to go to a professional oral health care institution for consultation and treatment, rather than listening to some folklore that mouthfuls of white wine can cure a toothache.
