If you’re dealing with a severe toothache, try to rinse your mouth with warm saltwater to get some temporary relief. Salt has natural disinfectant properties, which may reduce inflammation and control bacteria. Swishing can also loosen food particles between your teeth that are maybe causing irritation. Another home remedy for tooth pain is applying a cold compress to the outside of your cheek. It may help numb the pain and reduce swelling. If you’re still in severe pain, you may consider calling your emergency dentist for more safe and helpful tips.
