If you’re having continual discomfort from a toothache, here are some steps to resolve the problem. Brush and floss your teeth to remove food fragments on or in-between your teeth. Rinse with warm water. If your gums are swollen, put a cold compress on the outside of your mouth. It’s recommended not to place an aspirin or any other painkiller against the gums near the aching tooth as it can burn and cause gum tissue damage. If the pain perseveres, call to see a dentist as soon as possible.
