You can get rid of a toothache by mixing some salt with some warm water and then gargling the warm salt water in your mouth to help get rid of the toothache pain to go away.
Try taking some pain medicine too and even freezing a tea bag and placing the frozen wet tea bag between your teeth or on your gums where the tooth is hurting.
Sucking on ice can also help relieve a toothache.
If your toothache doesn't go away or seems to get worse you should see a dentist to make sure the tooth isn't seriously infected as a serious tooth infection can cause other serious problems such as hear conditions etc.
