Essential oils, like peppermint, clove, & tea tree oil, are often believed to be effective techniques as an alternative medicine to provide relief in dry mouth condition. But they cannot treat the underlying causes.
Tea tree oil, oregano oil, thyme oil, cinnamon oil, grapefruit oil, clove oil, and lemongrass oil have strong antibacterial properties that can fight infections like Staphylococcus aureus and Escherichia coli.
Clove oil has been used for treating dental pain for centuries. However, this is not the only use for this essential oil. Clove oil benefits also include treating acne, asthma, indigestion, cough and blood impurities.
Clove oil has a substance called Eugenol which works like magic in a toothache. Clove oil reduces pain and swelling when you have a toothache. But a dental cavity is a systemic issue, and therefore clove oil is merely a temporary fix for a toothache.
