Types of Dental Root Fractures

A tooth fracture occurs when there is a break in the hard shell of a tooth. Although the enamel acts as a shield against disease and bacteria, a fracture can compromise this protective layer. If a crack is deep enough, germs can penetrate the pulp cavity and cause an infection.

There are several types of dental root fractures, including:

• Oblique subgingival fractures
• Oblique supragingival fractures
• Oblique root fractures
• Vertical apical fractures
• Vertical furcation fractures
• Vertical root fractures

Oblique Fractures

Subgingival Fractures

Oblique subgingival fractures extend below the gum line. The severity of the fracture depends on how far it has gone past the gum line. These fractures are usually painful as the fractured tooth usually remains in the gums after it breaks off. However, patients may have a subgingival fracture for years before feeling any pain.

Supragingival Fractures

This type of oblique fracture only affects the tooth’s crown and does not extend below the gum line. Usually, a supragingival fracture results in the affected part of the tooth breaking off. Patients typically experience little pain as the nerves and blood vessels of the pulp remain intact and undamaged. Although this fracture may not cause immediate pain, it can lead to infection or pain in the future without treatment.

Root Fractures

Oblique root fractures do not usually affect the surface of the tooth at all. The damage occurs below the gum line, particularly under the bone. While this classification of fracture is not visible, it is very painful. Patients with oblique root fractures may require root canal treatment or extraction, depending on how close the fracture is to the tooth fracture.

Vertical Fractures

Apical fractures

Vertical apical fractures occur at the apex or tip of the tooth root. Many patients with vertical apical fractures ask for extraction because of the severe pain it causes. The severe pain is a result of tooth fragments placing pressure on the bone. Root canal therapy can help alleviate the pain, but some cases may require tooth extraction. Patients can discuss the best treatment option with our dentist.

Furcation fractures

When the roots of a tooth separate, a vertical furcation fracture occurs. This type of fracture almost always affects the tooth’s nerves. Patients affected by this fracture experience pain and difficulty with simple tasks like eating and speaking. Root canal therapy and a crown can usually save teeth affected by vertical furcation fractures as the tooth does not generally split completely.

Root Fractures

A vertical root fracture happens when part of the tooth root breaks off. This type of damage is not common and usually occurs in teeth with endodontic treatment like root canal therapy. An apicoectomy may save the tooth if the vertical root fracture is short. Extraction is usually the common treatment; however, various studies have attempted to reunite fractured roots with varying success rates.
