How do you stop a tooth ace?

To stop a toothache, you can take over-the-counter pain relievers like ibuprofen or acetaminophen to alleviate pain and reduce inflammation. Rinsing your mouth with warm salt water may help soothe the affected area and cleanse any debris. Applying a cold compress on the outside of your cheek can also reduce swelling. However, it's essential to see a dentist as soon as possible to address the underlying issue.
