Cross Section of an Infected Tooth

Located inside the tooth are the blood vessels and nerves of the tooth. This collection of tissue is called the “pulp”. Dental decay allows bacteria to get into the pulp and kill the tissue. The tissue dies, and an infection starts. The pus drains out of the tooth roots and causes pressure and pain. An abscess can develop. This appears as a white-filled pimple along the gum tissue.

Recognizing and Treating an Infected Tooth

An infected tooth, often caused by deep decay, trauma, or cracks, is a dental emergency that requires prompt attention. If left untreated, an infection can spread to the surrounding bone and even lead to serious health complications. In this educational video, Dr. Michael Nugent, a trusted dentist in Pasadena, TX, explains how infections develop inside a tooth and what treatment options are available.

Common signs of an infected tooth include persistent pain, swelling, sensitivity to hot or cold, and even fever or swollen lymph nodes. Depending on the severity of the infection, treatment may involve root canal therapy to remove the infected pulp or, in more serious cases, extraction to prevent further damage. Dr. Nugent uses digital X-rays and years of clinical expertise to diagnose and treat infected teeth with precision and care.
