Patients eat garlic when the toothache, there is no role in relieving toothache. Toothache eat garlic belongs to folk remedies, does not have any scientific basis, although garlic has a certain antibacterial effect, but can not relieve toothache. The vast majority of people’s toothache is due to pulpitis, deep caries, apical periapical inflammation, periodontitis, or wisdom teeth periapical inflammation caused by a series of dental disorders, the correct way to alleviate the toothache is to immediately consult a doctor to find out the specific disease and then symptomatic treatment. If the tooth is infected with dental caries, it should be treated with resin filling in time. If the infection has spread to the pulp of the tooth, causing pulpitis or even periapical inflammation, the pain will be relatively severe, in which case the tooth needs to undergo root canal treatment to remove the pulp nerve before the pain can be relieved. For periapical lesions or acute stage of wisdom tooth pericoronitis, first of all, we need to use a sufficient amount of antibiotics to reduce inflammation, and for the pain caused by wisdom tooth pericoronitis, we need to remove the wisdom tooth after the inflammation is completely eliminated.
