If you constantly have a toothache or the toothache doesn't go away you need to see a dentist because a tooth infection can become serious.
But if you can't get to the dentist for your toothache you can get rid of the toothache by swishing some warm salty water in your mouth around your teeth.
Just gargle the salty water for a minute or so and then spit it out. You may have to gargle a few times throughout the day to help ease the toothache.
Sucking on some ice or even a warm tea bag can help get rid of a toothache too.
Also take some aspirin or other painkillers which can help ease the toothache.
I find that Gargling with Apple Cider Vinegar also helps to get rid of a toothache.
Apple Cider Vinegar contains antibacterial properties which can kill off bacteria that may be causing your tooth infection.
So pick up some Apple Cider Vinegar and try gargling some Apple Cider Vinegar as it helps me to get rid of my toothaches.
