A root canal is a dental procedure that has garnered attention, often due to myths and misconceptions about its nature and purpose. In essence, it is a life-saving remedy for teeth that have been compromised internally, often because of deep cavities, infections, or physical trauma. One of the frequent culprits leading many to undergo this procedure is a cracked tooth. These cracks, sometimes invisible to the naked eye, can pave the way for bacteria to reach the sensitive pulp of the tooth, causing pain and inflammation. This article delves into the intricate relationship between root canals and cracked teeth, helping readers understand their options and the significance of timely intervention.

The Anatomy of a Tooth

The tooth, an essential component of the oral cavity, is more than what meets the eye. Beyond its hard exterior lies a complex structure, each layer having a unique function and importance. A basic understanding of this anatomy is crucial in grasping how and why certain dental issues, like cracks, can become problematic.

Enamel: The Tooth’s Shield

The outermost layer, tooth enamel, is the hardest and most mineralised substance in the human body. It acts as the first line of defence against physical and chemical damage, protecting the inner layers of the tooth.

Dentin: The Middle Ground

Situated beneath the enamel, dentin is slightly porous and less hard. This layer transmits nerve signals. It provides support to the enamel, playing a crucial role in the tooth’s overall health.

Pulp: The Heart of the Tooth

Located at the centre, the pulp houses blood vessels, nerves, and connective tissue. It nourishes the tooth and responds to external stimuli, making it a vital component. However, it’s also the most vulnerable part, especially when cracks in the tooth occur.

Understanding the anatomy of the tooth not only underscores its complexity but also emphasises the need for proper care and attention to ensure overall oral health.

Causes of Tooth Cracks

Tooth cracks, though sometimes imperceptible, can lead to significant dental problems if left unaddressed. The causes of these fissures are multifaceted, often arising from a combination of external forces and internal susceptibilities. Let’s delve deeper into the primary culprits behind tooth cracks.

Physical Trauma:

Accidents falls, or any direct blow to the mouth can cause cracks. Sports enthusiasts, especially those involved in contact sports without protective mouth gear, are particularly at risk and as a result tooth’s chewing surface breaks.

Thermal Stress:

The repeated exposure of teeth to extreme temperature changes, like sipping hot coffee followed by cold water, can cause them to expand and contract. Over time, this can lead to tiny fractures known as craze lines.

Biting on Hard Objects:

Teeth are sturdy, but they’re not indestructible. Chewing on hard foods like ice cubes, hard candy, or non-food items like pen caps can introduce cracks.

Previous Dental Work:

Teeth that have undergone extensive dental procedures, such as large fillings or multiple restorations, can become weakened and more prone to cracking.

Age and Wear:

With age, our teeth naturally undergo wear and tear. Older adults, especially those above 50, may be more susceptible to tooth cracks.

Understanding the primary causes of tooth cracks is the first step in prevention. Regular dental check-ups can detect and address these issues early, reducing the risk of complications.

Identifying a Cracked Tooth

Cracked teeth can sometimes be elusive, presenting symptoms intermittently or mimicking other dental issues. However, early identification is paramount to prevent complications and safeguard oral health. Here’s how one can spot different types of cracked teeth.root canal treatment gordon

Cracked Tooth Symptoms to Watch For:

  • Pain and Sensitivity: Often sharp and erratic, pain might occur when biting down or be triggered by hot, cold, or sweet foods and beverages.
  • Discomfort while Biting: A sensation that something’s “off” when biting or chewing is a common sign.

Diagnostic Tools:

  • Dental X-rays: While not all cracks are visible on X-rays, they can still reveal issues in the tooth’s surrounding structures.
  • Dental Probes: Dentists may use these thin instruments to feel for the crack or check areas where gum pockets may have deepened due to a fracture.
  • Transillumination: By shining a light through the tooth, cracks may become more evident as they interrupt the light’s passage.

Regular dental examinations remain the most effective way to catch and address cracks early. If any symptoms arise, seeking prompt dental consultation is advised.

The Connection Between Cracked Teeth and Root Canals

At a glance, a cracked tooth syndrome may seem like a minor mishap, merely a cosmetic concern. However, the implications run deeper, quite literally, as these fractures can jeopardise the inner sanctum of a tooth, necessitating interventions like root canals.

Cracks and Pulp Exposure:
Cracks, especially those deep and extensive, like a vertical root fracture, can pave the path for bacteria to infiltrate the tooth. Once inside, they can easily reach the pulp of a broken tooth– the tooth’s vital centre is filled with nerves and blood vessels. This invasion can lead to pulpitis, an inflammation of the pulp.

Why a Root Canal Treatment?:
With the onset of pulpitis, the pulp becomes vulnerable to bacterial infection. If left untreated, this can escalate to an abscess, a painful, pus-filled pocket in a tooth that is cracked. Root canal tooth procedure comes to the rescue here. It involves removing the inflamed or dead pulp tissue, cleaning and disinfecting the inner chambers, and then sealing them. The primary goal? Save the tooth and alleviate pain.cracked tooth syndrome gordon

Preservation Over Tooth Extraction:
Cracks that lead to compromised pulp don’t always mean the loss of the root canal tooth. Root canals offer a preservation method, enabling the retention of the natural tooth while preventing the spread of infection.

In essence, while cracks initiate the problem, root canals offer a restorative solution for vertical root fractures, underscoring the intricate relationship between the two in the realm of dental care.

Tips for Prevention and Post-Treatment Care

Maintaining the health of our teeth requires a blend of preventive measures and attentive post-treatment care. Whether it’s ensuring cracks don’t occur or caring for a tooth after a dental procedure, here are some indispensable tips.


  1. Regular Dental Check-ups: Routine examinations can detect potential problems early, reducing the risk of severe issues.
  2. Wear Protective Gear: If involved in contact sports, always wear a mouthguard to shield teeth from trauma.
  3. Mindful Eating: Avoid chewing on hard foods or objects like ice, hard candies, or pen caps, which can cause cracks.
  4. Good Oral Hygiene: Regular brushing and flossing can keep harmful bacteria at bay.

Post-Treatment Care:

  1. Follow Dentist’s Instructions: After procedures like root canals, adhere strictly to the dentist’s guidelines to ensure optimal healing.
  2. Pain Management: Use prescribed or topical oral pain medications as recommended.
  3. Avoid Pressure: For a few days post-treatment, avoid chewing or biting the affected tooth.

By intertwining preventive habits with diligent post-care, one can ensure the longevity and health of their teeth.


Dental health, while rooted in the microscopic intricacies of our teeth, plays a monumental role in our overall well-being. From understanding the depths of tooth anatomy to recognising the signs of potential problems, it’s evident that proactive care and timely interventions are paramount. Whether it’s the preventive steps to avoid cracks and a split tooth or post-treatment measures to ensure swift healing, every action contributes to a brighter, pain-free smile.

Remember, dental issues rarely fix themselves. If you suspect a problem or simply wish to stay ahead with regular check-ups to maintain tooth structure, don’t hesitate. Contact the experts who prioritise your oral health.
