A dental infection, also known as a tooth abscess, is a serious condition that can cause severe pain and discomfort. It occurs when bacteria invade the nerve of the tooth, causing inflammation and pus to accumulate in the surrounding tissue. The most common symptoms of a dental infection include severe toothache, sensitivity to hot and cold temperatures, swelling of the gums, and fever.
