A toothache is a pain in or around a tooth. It can be caused by a variety of factors, including tooth decay, gum disease, and injury. Toothaches can be mild or severe, and they can last for a few hours or several days.
There are a number of things that can be done to alleviate a toothache. Some simple home remedies include rinsing the mouth with warm salt water, applying a cold compress to the face, and taking over-the-counter pain medication. If the toothache is severe or does not improve with home remedies, it is important to see a dentist as soon as possible.
