Curved tooth roots, a condition known as dilaceration, are primarily caused by trauma that occurred during the tooth's root development.
Understanding Dilaceration
Dilaceration refers to an abnormal bend or curve in a tooth root, and sometimes in the crown of the tooth as well. This deviation from the normal tooth axis can present challenges in dental procedures and may affect the tooth's long-term health.
Causes of Curved Tooth Roots
The primary cause, according to research, is trauma during the root development stage. This trauma can disrupt the normal process of root formation, leading to a curved or angled root.
Trauma During Development:
- Physical Injury: An impact or injury to the face or jaw during childhood, when teeth are still developing, can displace the developing tooth bud.
- Movement: According to the reference material, movement of the crown, or both the crown and part of the root, from the remaining developing root can result in sharp angulation after the tooth completes its development. This is illustrated in figure that supports the reference.
- Crowding: Lack of space can sometimes cause teeth to develop in unusual positions.
Implications of Curved Tooth Roots
While curved tooth roots might not always cause noticeable problems, they can complicate certain dental treatments:
- Root Canal Therapy: The curved shape can make it difficult to access and clean the root canal system.
- Tooth Extraction: Removing a tooth with a curved root can be more challenging and may require a surgical approach.
Addressing Curved Tooth Roots
Treatment options depend on the severity of the curve and the symptoms you're experiencing. Your dentist can evaluate your specific case and recommend the most appropriate approach.
