Cracked Tooth

Cracked and fractured teeth are common dental issues that can cause significant discomfort and lead to further complications if left untreated. With advancements in dental technology, more people are retaining their natural teeth for longer periods, increasing the likelihood of experiencing cracked teeth. There are various reasons why teeth may crack, including biting on hard objects, trauma, and grinding or clenching of teeth, which place additional strain on the teeth and make them more susceptible to cracks.

When tooth enamel is cracked, pain can be intense, especially when pressure is exerted on the crack during biting. As the crack widens with biting action, the underlying pulp and inner structure of the tooth become exposed, resulting in painful irritation. When pressure is released, the crack closes, and the pain subsides temporarily. If left untreated, the pulp can become irreversibly damaged, leading to constant pain and potential infection that can affect the surrounding bone and soft tissues.

Common symptoms of a cracked tooth include unexplained pain while eating, sensitivity to hot and cold foods, spontaneous pain without an obvious cause, and difficulty pinpointing the location of the pain.

Different types of cracks can affect teeth, and the appropriate treatment depends on the specific type of crack. In cases where the crack is not too deep, root canal therapy may be performed to save the natural tooth. However, if the tooth is severely damaged, extraction may be necessary.

Here’s an overview of common types of cracks:

1. Crazes: These are small vertical cracks on the tooth surface that are considered normal and rarely require treatment for health reasons. Cosmetic treatments can be performed to address any aesthetic concerns.

2. Oblique supragingival cracks: These cracks affect only the crown of the tooth above the gum line. The affected part may eventually break off, but there is typically little pain since the tooth pulp remains unaffected.

3. Oblique subgingival cracks: These cracks extend below the gum line and often beyond the jawbone. The broken piece may remain attached and require periodontal surgery to expose the crown for restoration.

4. Vertical furcation cracks: These cracks occur when the roots of the tooth separate. Root canal therapy and a crown can usually save the tooth.

5. Oblique root cracks: These cracks are not visible on the tooth surface and occur below the gum line. Treatment options depend on the proximity of the fracture to the tooth surface, but extraction is often necessary.

6. Vertical apical root cracks: These cracks occur at the tip of the root and can be extremely painful. Root canal therapy may provide temporary relief, but extraction is typically required.

Treatment for cracked teeth depends on the extent and location of the crack. Root canal therapy is often the preferred option when the tooth root is affected, with the pulp, nerves, and vessels being removed and the space filled with a material called gutta-percha. A crown or filling is then placed to stabilize the tooth. In severe cases where the tooth cannot be saved, extraction is performed, and restorative options such as bridges, dental implants, or partial dentures may be considered to restore function and aesthetics.

If you have any concerns about cracked teeth, it is important to consult your dentist for a proper evaluation and appropriate treatment recommendations.
