If you’re experiencing continued discomfort from a toothache there are some steps you can take to resolve the problem or at least bring temporary relief till seeing a dentist. Brush and floss your teeth to remove any food particles on and in-between your teeth. Then rinse your mouth with warm water. If you notice any swelling on your gums, put a cold compress on the outside of your mouth. Do not put aspirin or any other painkiller against the gums near the aching tooth as it can burn and damage gum tissue. If the pain persists, schedule an appointment with your dentist as soon as possible.
