For tooth pain, eating garlic is not a contraindication for it, but it is not particularly helpful either, that is, eating garlic after tooth pain does not have a therapeutic effect, does not make the pain less, and generally does not make it worse. In the majority of cases, tooth pain is caused by bacterial infection of the tooth, causing pulpitis or periapical inflammation and causing pain. In this case, the best way is to go to a professional dentist and have the tooth treated with pulpal drainage, and the pain will be relieved immediately. Garlic is a food often consumed by people, and it contains allicin, which has certain bactericidal and antibacterial functions, but its effect on tooth pain is very limited because it cannot penetrate into the pulp or the root tip to produce effects, and its effect will not correspond to the corresponding parts after eating.
