Cold Compress
Using an ice pack or a cold compress on the affected tooth can help alleviate pain caused by a tooth infection. This is especially effective when the ache is the result of swollen gums or injury. You only need to hold a bag of frozen veggies, ice pack, or cold compress against the outside of your cheek, right above the affected area. Keep it for a few minutes to get temporary relief. Low temperatures make the blood vessels become constricted, which slows the blood flow to the infected tooth. As a result, it can alleviate inflammation and swelling as well as ease the pain. [8]
