### What Is a Tooth Abscess? A tooth abscess happens when a tooth fills with pus and other infected material. This occurs after the center of a tooth becomes infected with bacteria. It’s typically a result of tooth decay or a broken or chipped tooth. Bacteria can seep into the tooth’s center (pulp) when the tooth’s enamel is broken. ### Symptoms After the tooth is infected, pus collects inside the tooth and causes swelling and pain commonly known as a toothache. Without proper attention, the infection can spread from the pulp and out to the bones supporting the teeth. Pain is the main symptom of a tooth abscess. Other symptoms may include: - Swelling in the face or cheek - Sensitivity to hot and cold temperatures - Fever - Swollen lymph nodes ### Temporary Relief If you can’t see your dentist immediately, you can use over-the-counter pain relievers or warm salt-water rinses to ease the pain and provide temporary relief. ### Treatment Only your dentist can treat a tooth abscess. Your dentist’s main goal will be to save the tooth by draining the abscess and ridding the mouth of infection. Antibiotics may be given to fight the infection. A root canal may be needed in order to save the tooth. If the tooth cannot be saved and the infection is serious enough, the tooth may need to be removed. In severe cases, hospitalization may be required to prevent the infection from causing more intense problems.
