Clove is considered to be the best remedy for toothache. Clove is known for its anti-bacterial, anti-inflammatory, anesthetic and antioxidant properties. For toothache relief you will have to dab a small cotton ball in clove oil and apply directly to the infected tooth. You can also make clove oil rinse by adding a few drops of it in ½ glass water, mix well and gargle. If you do not have clove oil you can grind some cloves and add them to cooking oil (few drops) and apply this mixture to the aching tooth.
The antibiotic properties of garlic are effective in inhibiting the growth of the bacteria in the mouth, which saves us from tooth decay. Take a clove of garlic and finely crush it with some salt and apply. In case you do not have fresh garlic you can use garlic powder in the same manner.
