To relieve a toothache, you can try the following remedies:
Rinse your mouth with warm salt water. This can help clean the area around the tooth and reduce swelling and pain. To make the rinse, mix 1/2 teaspoon of salt in a cup of warm water, and rinse your mouth with the solution for 30 seconds to 1 minute.
Apply a cold compress to the outside of your cheek. This can help numb the pain and reduce swelling. To make a cold compress, wrap a few ice cubes in a clean cloth, and hold it against your cheek for 10-15 minutes at a time.
Take over-the-counter pain medication. Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or aspirin, can help reduce inflammation and relieve toothache pain. Follow the instructions on the package, and do not exceed the recommended dose.
Use clove oil. Clove oil has natural pain-relieving and antimicrobial properties, and it can be effective in reducing toothache pain. To use clove oil, put a few drops on a cotton ball, and apply it directly to the affected tooth. You can also mix the clove oil with a little olive oil or water to dilute it.
Remember that these remedies are only temporary, and they do not address the underlying cause of the toothache. If the toothache persists or is severe, you should see a dentist as soon as possible for a proper diagnosis and treatment.
