Ice pack or cold compress
You could also apply an ice pack or cold compress to help ease any pain that you are experiencing from a toothache caused by swollen gums or injuries. When you apply it, the pack will cause the blood vessels around affected areas to constrict, thus alleviating the pain, inflammation, or swelling. In this approach, you need to hold a towel-wrapped bag of frozen ice against the outside of your cheek, right above the painful teeth. Keep it for around 15 minutes at a time and repeat every few hours for quick results. [4]
