Most Common Root Fractures in Teeth

Tooth root fractures are dental injuries that involve the fracture or breakage of the root portion of a tooth. These fractures can occur due to various reasons, such as trauma, dental decay, or weakened tooth structure. Below are some common types of tooth root fractures.

Types of Root Fractures

Horizontal Root Fracture

This type of fracture occurs horizontally along the root of the tooth. It can be located in the middle or apical (near the tip) third of the root. The fracture line can extend from the outside of the root to the inside (pulp chamber) or vice versa.

Vertical Root Fracture

A vertical root fracture is a type of dental injury that occurs in the root of a tooth. Unlike other types of tooth fractures that involve the crown or the visible part of the tooth, a vertical root fracture affects the root portion of the tooth that is below the gumline and not visible to the naked eye.

Vertical root fractures typically begin in the root and extend upward toward the crown of the tooth. They can be caused by various factors, such as trauma to the tooth, excessive biting forces, or even natural weakening of the tooth structure due to age or dental procedures.

Vertical root furcation refers to a dental condition characterized by the separation or division of the roots of a tooth into two or more distinct branches. It occurs when the roots of a tooth divide at a level below the gum line, creating a deep furcation defect. Vertical root furcation can be caused by various factors such as periodontal disease, trauma, or anatomical abnormalities. This condition poses a significant challenge for dental professionals as it can lead to compromised stability and function of the affected tooth. Treatment options may include root planing, regenerative procedures, or even extraction in severe cases. Early detection and appropriate management are crucial to prevent further deterioration and preserve oral health.

Vertical apical root fracture is a dental condition where a crack occurs in the root of a tooth, extending vertically from the apex. It is usually caused by trauma, such as excessive force during dental procedures or accidents. Treatment options depend on the severity of the fracture and may include extraction or root canal therapy.

Oblique Root Fracture

Oblique root fractures are diagonal fractures that occur on an angle. They can extend from the crown to the root or vice versa. The fracture line usually starts from the outside of the root and progresses inward or vice versa.

Split Root

A split root fracture occurs when the root of a tooth splits into two separate segments. It can be caused by trauma, excessive biting forces, or weakened tooth structure. Split root fractures often require extraction of the affected tooth.

Treatment for tooth root fractures may vary depending on the severity, location, and other factors. In some cases, root canal treatment, splinting, or extraction may be necessary. If you suspect you have a tooth root fracture, it is best to consult your dentist for diagnosis and appropriate treatment.
