Toothaches and sore tooth

First, thoroughly rinse your mouth with warm water ( if it does trigger the ache). Use dental floss to remove any lodged food. If your mouth is swollen or starts to swell, apply a cold compress to the outside of your mouth or cheek. Never put aspirin or any other painkiller against the gums near the aching tooth because it may burn the gum tissue. See your dentist as soon as possible.
