A perio-endo lesion is a dental condition that involves both the periodontal (gum and supporting structures) and endodontic (pulp and root canal) tissues of the tooth. This complex issue can present as a challenge to both the patient and the dentist, requiring careful diagnosis and treatment. At Nuffield Dental, Dr. Irene Sim specialises in addressing these types of lesions, helping patients understand the condition and the available treatment options.
What Is a Perio-Endo Lesion?
A perio-endo lesion occurs when there is a connection between an infection in the tooth’s pulp (endodontic) and an infection in the surrounding gum tissues (periodontal). These infections can either originate in the tooth’s pulp and spread to the surrounding periodontal structures, or they can begin as a gum infection that spreads to the root canal system. In some cases, the infection can arise simultaneously from both areas, making diagnosis and treatment more complex.
What Are the Symptoms?
Patients with a perio-endo lesion may experience the following symptoms:
- Tooth pain or sensitivity: Pain can occur when biting or chewing, or the tooth may be sensitive to temperature changes.
- Swollen or bleeding gums: Gum swelling or bleeding around the affected tooth can be a sign of periodontal involvement.
- Pus or drainage: In more advanced cases, pus may drain from around the gumline or through a small bump (fistula) on the gum.
- Tooth mobility: The affected tooth may become loose if the surrounding bone is damaged by the infection.
What Does It Mean for the Patient?
A perio-endo lesion often indicates a serious infection that requires prompt treatment. If left untreated, the infection can spread, leading to bone loss, tooth mobility, and eventual tooth loss. Treatment typically involves both root canal therapy to address the endodontic infection and periodontal treatment to manage the gum infection.
In some cases, surgical intervention may be required to clean the area more thoroughly and promote healing. Early detection and treatment are crucial for preserving the tooth and preventing further damage.
How Can It Be Treated?
At Nuffield Dental, Dr. Irene Sim will perform a thorough evaluation, including digital imaging, to determine the extent of the lesion. Treatment may involve root canal therapy, deep periodontal cleaning, or, in advanced cases, surgical intervention to eliminate the infection. By addressing both aspects of the lesion—periodontal and endodontic—patients can achieve long-term healing and tooth preservation.
