Symptoms of a Cracked Tooth

There are five kinds of cracked teeth: craze lines, fractured cusps, cracks extending into the gum line, split teeth, and vertical root fractures. Each type of cracked tooth shows different symptoms. Craze lines have tiny, painless cracks in the teeth enamel, and they typically do not require any treatment. Fractured cusps usually occur around dental fillings without affecting the tooth’s pulp, and they are generally painless. Usually, teeth with cracks that have reached the gum line require immediate extraction; however, they may still be salvageable if the crack has yet to reach the gum line.

Split teeth have cracks extending from the surface to below the gum line and can typically be separated into at least two segments. Such teeth generally cannot be saved as a whole. Teeth with vertical root fractures have cracks that begin from below the gum line and extend upwards. With all types of cracked teeth, patients may experience pain when chewing or biting, tooth sensitivity, swelling of the gum around the affected tooth, and intermittent pain.

Cracked Tooth Syndrome (CTS)

Cracked tooth syndrome, abbreviated to CTS for short, is a condition in which a patient has a crack in their tooth that is too small to be seen on an X-ray. Alternatively, the patient’s tooth may have a crack that is difficult to locate due to it being under the gum. CTS most commonly affects molars, and its most common symptoms include tooth sensitivity and pain or discomfort when biting down. CTS pain is unlike cavity pain in that it is not persistent; instead, it comes and goes intermittently.

There is no singular cause of CTS. However, specific populations may be more prone to CTS than others. Patients with malocclusions that cause them to put excess pressure on one tooth, patients who grind or clench their teeth, patients with large fillings, or patients who have undergone root canal treatment are all more likely to have CTS than their counterparts. Furthermore, as CTS is also one of the most challenging dental problems to diagnose, patients may experience unexplained symptoms for months.

Cracked Teeth & Root Canals

As stated by MedicalNewsToday, the best treatment method for a cracked tooth is dependent on its location and the extent of its damage. Some, like teeth with tiny cracks that do not cause any pain or discomfort, may be minor enough to not require treatment. Minor treatment options include glue, plastic resin (also known as bonding), fillings, or crowns. For more severe cases, root canal treatment may be necessary.

During a root canal procedure, the endodontist removes any infected or inflamed pulp. They then clean and shape the inside of the root canal before filling it. Afterward, a crown is placed on the tooth’s cap to protect and fully restore its functionality. Once restored, the treated tooth will continue to function as any other natural tooth. See What is an Endodontist?

When a Cracked Tooth Is Beyond Repair

Cracked teeth that are not treated in time may eventually cause pulp necrosis, a condition in which the tissue inside the teeth dies. This may set off a domino effect of disastrous effects on one’s oral and overall health, including total teeth loss. Teeth may be totally beyond repair if the crack extends below the gum line. At that point, tooth extraction will become the only viable option.

Though today’s tooth replacement options are better than ever, it is still best to save a natural tooth whenever possible. Accordingly, patients should seek endodontic help as soon as they suspect they may have a cracked tooth. Early detection is critical for proper and effective treatment, and endodontic surgery may be adequate for more severe cases. Rohan S. Toor, DDS can help determine what is best for each patient on a case-by-case basis.

Aftercare for a Repaired Cracked Tooth

Unlike in broken bones, the fractures in a cracked tooth will not heal. Some cracks may even continue to grow until they separate, leading to total tooth loss. Crowns protect the treated teeth, but even they are not foolproof. Fortunately, endodontic retreatment is possible if any treated teeth heal improperly or become reinfected due to external factors.

Knowing how to care for a repaired cracked tooth is arguably just as important as having it treated in the first place. With improper aftercare, patients may inadvertently worsen the pain and have the crack spread. Some pain or discomfort may follow most cracked tooth treatment options; however, this should be easily managed with painkillers (either prescribed or over-the-counter). Rohan S. Toor, DDS also provides patients with post-treatment instructions to ensure the best results.

Dental Terminology

Cementum
Cementum is that bone-like tissue that forms the outer surface on the root of the tooth.
Dental Pulp
Dental pulp is the inner-most layer of the tooth with connective tissue that contains blood vessels and nerve tissue.
Dentin
Dentin is the inner layer of the tooth structure that is immediately under the enamel and surrounds the dental pulp.
Direct Pulp Cap
A direct pulp cap is a procedure in which a professional treats exposed pulp with a therapeutic material to help the tooth heal.
Enamel
The enamel is the hard calcified layer that covers the entire tooth and is subject to interaction with multiple substances.
Endodontist
An endodontist is a specialist who focuses on treating issues, diseases and conditions that affect the inner-most layer of the tooth, the dental pulp.
Pulpectomy
A pulpectomy is a procedure that involves the complete removal of pulp tissue from the root canal in a tooth.
Pulpitis
Pulpitis is another term to describe the inflammation of the dental pulp due to an injury or infection.
Pulpotomy
A pulpotomy is a procedure involving the removal of a portion of diseased or infected pulp in order to protect the healthy portions of the pulp and teeth still in the mouth.
