What are advanced dental caries? Advanced dental caries (also called endodontic or root canal caries) are a more advanced form of dental caries that extends into the pulp chamber, the root canal system, or both. Advanced dental caries can cause pain, infection, and significantly affect your daily life and long-term oral health. Fortunately, early diagnosis and treatment can help prevent the condition from worsening. If left untreated, even mild tooth decay can progress, leading to infections in surrounding tissues and, in rare cases, affecting other parts of the body.
However, with early detection and treatment by a dentist, these risks can be mitigated. To improve your chances of avoiding serious consequences of untreated tooth decay, it is important to understand what advanced tooth decay are as well as how they may be detected earlier than usual if you see a dentist twice a year for check-ups instead of once every six months like most people do.

What causes Advanced Dental Caries?
While dental caries is a normal process, it typically starts in the tooth surface, progresses through the enamel into the dentin (the toothβs middle layer), and then into the pulp chamber.
If the bacterial infection reaches the pulp chamber, your tooth may become infected.

If the infection is left untreated, the bacteria in your tooth may grow inside the tooth, which can result in tooth death. This condition known as dental pulpitis or dental pulp death may lead to tooth loss.
In some cases, dental caries may also extend into the root canal system. Once the dental caries reach the root canal system, you may experience pain, swelling, and a bad taste in your mouth.
If the tooth decay are left untreated, the infection can spread to other parts of your body.
