Types of Dental Root Fractures New Rochelle, NY
Like any part of the body, your teeth will start to show signs of wear and tear over the years. Sometimes that can come in the form of a dental root fracture. Root fractures are when a tooth crack reaches into the deepest layers of the tooth. They may happen in any direction and generally fall into two categories: vertical and oblique fractures.
If you suspect you may have a root fracture, do not wait to see the dentist. Treatment is available for dental root fractures at Zen Dentistry Westchester in New Rochelle and the surrounding area. To learn more about the types of dental root fractures and the various treatments we provide, call us at (914) 826-8363 to schedule a consultation.
Layers of the Teeth
Teeth consist of several layers and include four types of tissues. Enamel, dentin, and cementum make up the hard tissues. The pulp, which contains the nerves, blood vessels, and connective tissues, is soft tissue.
The part of the tooth that is visible in the mouth is called the crown. The crown consists of a hard outer shell called enamel. The tooth root spreads down from the crown into the gum line and jawbone, holding your tooth in place.
The second layer is called the dentin, which contains the pulp chamber at the tooth center. Extending down from the pulp chamber and into the jawbone is the root canal, a passageway for nerves and blood vessels. When root fractures extend this far, it is important to see a dentist for treatment.

Root Fracture Types
Root fractures occur when the crack involves the dentin, cementum, and pulp. They typically separate into two types—oblique and vertical. A vertical root fracture involves the entire length of the tooth or just a section of it. An oblique root fracture occurs when the crack runs along the tooth length. Vertical and oblique root fractures require different treatment approaches with varying levels of success.
A fracture that goes deep into the layers of the tooth can affect the health of the entire tooth and even the ones surrounding it. A root fracture exposes the inner layers of the tooth to bacteria, leading to an infection. An untreated infection can lead to extreme discomfort while chewing and sensitivity to hot and cold foods.

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.

Frequently Asked Questions
Q. How does a root fracture happen?
A. Root fractures can result from a traumatic injury or can happen in teeth with previous procedures like a root canal or crown. Healthy teeth can also be subject to cracks by chewing on hard materials and foods like popcorn kernels. Your treatment will depend on the complexity of the situation and the long-term prognosis of the tooth.
Q. What are the different types of root fractures?
A. There are vertical and oblique or horizontal fractures. Oblique fractures run side to side along the tooth and only make up about 3% of dental injuries. Vertical fractures start at the root and progress up toward the crown.
Q. What are some of the symptoms of root fracture?
A. Not all root fractures present symptoms, leaving them undetected if you do not see the dentist regularly. When there are symptoms, they can include discomfort or pain when biting or chewing food, sensitivity to hot and cold, and gum swelling. These symptoms may also come and go.
Q. How are root fractures treated?
A. The severity of the crack will determine the treatment plan. Sometimes, you can stabilize the tooth, but you will need a root canal if the fracture reaches the pulp. In some cases, the root fracture may be so severe that you will need a tooth extraction.
Q. What happens after treatment for a tooth fracture?
A. Following the treatment, the patient will need to be careful with what they eat. This way, the tooth can continue to heal properly. We will also go over the necessary care techniques the patient can take at home to further the recovery process.
