Cracked tooth pain is a common yet often distressing dental problem, affecting a significant portion of the population at some point in their lives. This pain can arise from various forms of dental damage, such as a cracked tooth, a chipped or broken tooth, or even more complex conditions like cracked tooth syndrome. Understanding the causes, symptoms, and appropriate treatment options is essential for effectively managing this type of tooth pain.

A cracked or broken tooth can occur for several reasons, from biting down on hard foods or objects to sports injuries and teeth grinding. The severity of the crack can vary, with some being minor, affecting only the tooth enamel. In contrast, others can be more serious, extending to the dental pulp or causing a vertical root fracture. The location and depth of the crack significantly influence the intensity of the pain and the treatment required. For instance, a fracture that reaches the gum line or the tooth’s deeper layers can lead to more severe pain and require more complex treatment like root canal therapy.

The prevalence of cracked teeth has been increasing, partly due to greater awareness and improved diagnostic techniques. Only a dentist, with their special tools and expertise, can accurately diagnose the extent of a tooth fracture and recommend the best course of treatment. The most common causes of cracked or broken teeth include accidental trauma to the mouth, biting down on hard objects like popcorn kernels, or even drastic temperature changes in the mouth. Additionally, lifestyle habits such as grinding your teeth can contribute to the development of hairline fractures or craze lines in the teeth, which can lead to more significant cracks over time.



Prompt treatment is essential to prevent further damage to the affected tooth and to alleviate pain. Whether through pain medication, root canal treatment, or even tooth extraction, a dentist may offer various treatment options depending on the severe severity and the tooth’s overall health. See a dentist as soon as possible if you suspect you have a cracked or broken tooth, as early intervention can often save the tooth and prevent more serious complications such as nerve damage or gum inflammation.

Anatomy of a Tooth and How Cracks Occur 

Understanding the anatomy of a tooth is essential in comprehending how and why cracks develop. A tooth consists of several layers: the outermost layer is the hard, protective tooth enamel, followed by a softer, sensitive layer called dentin, and finally, the dental pulp at the core, which contains nerves and blood vessels.

Cracks in teeth, known as cracked tooth syndrome, can occur for various reasons. One of the most common causes is biting down on hard objects or foods, such as hard candies, ice, or popcorn kernels. This sudden pressure can cause the tooth enamel to fracture. Over time, repeated stress from chewing hard foods or grinding teeth can create microfractures, known as craze lines, which can develop into more significant cracks.

Other factors contributing to cracked teeth include sports injuries, accidents involving the mouth, or drastic temperature changes in the mouth (like eating something extremely hot followed by drinking something cold). Teeth undergoing extensive dental treatments, such as root canal therapy, may also be more prone to fractures due to weakened tooth structure.

Cracked Tooth Pain causes parramattaWhen a tooth cracks, it can lead to tooth pain, especially when chewing or exposed to extreme temperatures. If the crack extends below the gum line, it may result in a split tooth or a vertical root fracture, requiring prompt treatment by a dentist to prevent further damage. Sometimes, the pain may be intermittent and hard to pinpoint, making seeing a dentist regularly for check-ups essential.

Treatment options for a cracked or broken tooth depend on the extent and location of the crack. Minor fractures may only require dental bonding, while more significant ones might need a crown, root canal treatment, or tooth extraction. The best action is to seek dental advice as soon as possible to relieve pain and prevent further complications.

Types of Cracks and Associated Pain

Tooth cracks vary in type and severity, each presenting its unique pattern of cracked tooth pain. Understanding these variations is crucial for effective pain relief and treatment. Only a dentist with special tools and knowledge can accurately diagnose and suggest the best action for these dental injuries.

  • Craze Lines

These are tiny cracks that affect only the outer enamel of the tooth. Although superficial and rarely cause pain, they can be aesthetically displeasing. Craze lines are common and often do not require treatment unless for cosmetic reasons.

  • Fractured Cusp

Occurring around dental fillings, fractured cusps typically do not affect the tooth’s pulp and are less likely to cause pain. Prompt treatment, such as a new filling or crown, is usually sufficient to restore the tooth’s shape and prevent further damage.

  • Cracked Tooth

This type of crack extends from the chewing surface down towards the root. Early diagnosis is key to saving the tooth. A cracked tooth left untreated may lead to severe pain, especially if the crack extends into the pulp. This may necessitate root canal therapy or, in severe cases, tooth extraction.

  • Split Tooth

A split tooth is usually the result of an untreated cracked tooth. It is characterised by a crack with distinct segments that can be separated.

These cracks begin in the tooth’s root and extend towards the chewing surface. Often, they show minimal symptoms until the surrounding bone and gum become infected. Pain relief might require extraction, as the chances of saving the tooth are slim.

Each type of tooth crack can lead to different pain levels and require varied treatment options. In all cases, seeking prompt professional treatment from a dentist is crucial. They may use pain medication, root canal treatment, or other dental procedures to relieve pain, reduce swelling, and repair the affected tooth. Early intervention is the best way to prevent further damage and maintain oral health.

Symptoms Indicating a Cracked Tooth 

Identifying cracked tooth pain and distinguishing it from other types of dental pain is crucial for timely and effective treatment. Common symptoms of a cracked tooth include:

  1. Sharp Pain on Chewing: One of the most telling signs of a cracked tooth is a sharp pain when biting down or chewing. This pain often occurs suddenly and can be intense, especially when eating hard foods.
  2. Pain that Comes and Goes: Unlike constant toothache, cracked tooth pain is typically intermittent. It may appear and disappear, making it challenging to pinpoint.
  3. Sensitivity to Temperature: Cracked teeth often become highly sensitive to hot or cold temperatures. This sensitivity can range from mild discomfort to sharp pain.
  4. Pain when Releasing a Bite: Pain or discomfort may also occur when you stop biting down as the pressure on the tooth is released.
  5. Swelling of the Gum: Gum swelling around the affected tooth can indicate a crack, especially if it’s accompanied by pain.
  6. Discomfort with Sweet or Acidic Foods: Sensitivity or pain when consuming sweet or acidic foods is another common symptom.

Causes of Cracked Tooth Pain

Cracked tooth pain is a common dental issue, often resulting from various factors that weaken the tooth’s structure. Understanding these causes is key to prevention and effective treatment.

Chewing Hard Foods: One of the most common causes of cracked teeth is the habitual chewing of hard foods. Items like popcorn kernels, hard candy, and ice can exert excessive pressure on teeth, causing cracks. These cracks can penetrate through the tooth enamel, reaching the sensitive middle layer (dentin) or even the dental pulp, housing nerves and blood vessels, thereby causing pain.

The constant pressure and friction can cause tiny fractures (craze lines) on the tooth’s surface, which can develop into deeper cracks over time.

Physical Trauma: Sports injuries or accidents involving the mouth can result in fractured or broken teeth. Such impacts can cause immediate cracks or weaken the tooth structure, leading to cracks in the future.

Temperature Extremes: Exposing teeth to extreme temperature changes, such as eating hot food followed by a cold drink, can cause the tooth enamel to expand and contract rapidly. This can lead to cracks in the tooth.

Poor Oral Health: Neglecting oral hygiene can lead to tooth decay and gum disease, weakening teeth and making them more susceptible to cracks.

Age-Related Wear: As teeth age, they naturally wear down and may become more prone to cracks, especially if there’s a history of dental work like fillings, root canals, or crowns.


In conclusion, cracked tooth pain is a condition that requires prompt and professional dental care. From minor craze lines to severe fractures extending to the gum line, the types of tooth cracks and their associated pains vary greatly. Early detection and accurate diagnosis by a dentist are vital in preventing further damage, such as gum inflammation or nerve damage, and achieving effective pain relief.

Only a dentist can determine the best course of treatment, whether it involves simple pain medication, root canal therapy, or, in more severe cases, tooth extraction. Regular visits to the dentist for routine check-ups and addressing tooth pain or discomfort as soon as possible are key to maintaining oral health.
