Understanding Cracked Tooth 


Common Causes of Cracked Teeth

  • Trauma: Events such as falls, sports injuries, biting on hard substances, or unexpected blows to the face may lead to cracked teeth.
  • Teeth Grinding (Bruxism): Chronic clenching or grinding of teeth, often during sleep, places undue stress on the teeth, contributing to the development of cracks over time.
  • Ageing: Natural wear and tear as we age can make teeth more vulnerable to cracking.
  • Thermal Changes: Rapid changes in temperature from consuming hot and cold foods or drinks in succession can cause the teeth to expand and contract, leading to cracks.
  • Misaligned Biting: Teeth subjected to uneven chewing pressure due to misalignment or irregular biting habits may become more susceptible to cracking.

  • Sensitivity: Cracked teeth often exhibit discomfort to hot or cold stimuli, resulting in distress when consuming certain foods or beverages.
  • Pain While Chewing: A cracked tooth may manifest as an abrupt, sharp pain or discomfort when biting down or releasing pressure from a bite.
  • Unexplained Pain: Difficult-to-detect cracks can lead to persistent, untraceable dental pain, necessitating a professional examination.
  • Inflammation or Gum Sensitivity: A cracked tooth may occasionally induce swelling or tenderness in the gums nearby.


The Role of Root Canal Treatment


Explaining the Purpose of Root Canals for Cracked Teeth

Root canal treatment for cracked teeth aims to remedy the affected tooth when the protective enamel layer is breached, revealing sensitive inner parts like the dentin and pulp, housing nerves, blood vessels, and nourishing tissues. Root canal treatment becomes essential when a crack leads to damage or infection within these inner structures. Performed by a dentist, the treatment involves:

  • Removing the compromised pulp and nerve tissue.
  • Alleviating pain.
  • Halting infection spread to nearby areas.

Meticulously cleaning and sterilising the root canals is vital, as it wipes out bacteria and minimises the chances of additional issues and complications.


How Root Canal Treatment Can Save the Natural Tooth

Root canal treatment is crucial for saving a cracked tooth that might otherwise require extraction. With modern dental technology, retaining the natural tooth and eliminating the need for artificial replacement is possible. The treatment involves the dentist removing the infected pulp to alleviate pain and sensitivity. Then, cleaning, shaping, and sealing the root canals with a biocompatible material restores the tooth’s integrity, and further infection is thwarted. Often, the process is finalised with a dental crown or suitable restoration, strengthening the treated tooth and allowing it to function and appear like a healthy tooth. 



The Root Canal Treatment Process


Anaesthesia Administration and Ensuring Patient Comfort

Before beginning the root canal procedure, the dentist will inject local anaesthesia into the affected area, ensuring the patient is comfortable during the treatment. While the anaesthesia blocks the pain, patients might still feel some movement or sensation. For those with dental anxiety or facing a more complex case, additional sedation methods might be offered to induce relaxation or even a temporary state of unconsciousness. Open communication with the dentist about any anxieties or individual needs will help them choose the most appropriate anaesthesia option, contributing to a smooth and pain-free experience.


Accessing the Tooth’s Pulp and Root Canals

After the anaesthesia works effectively, the dentist will make a minor opening in the tooth’s crown. This access point allows entrance to the inner pulp chamber and root canals. Utilising this pathway, the dentist will meticulously remove the injured or infected pulp and any accumulated debris inside the canals. Pulp extraction is an essential step in the treatment, as it helps relieve pain and halts the further spread of infection.

After removing the pulp, the dentist will proceed to diligently clean and reshape the root canals using specialised tools. Cleaning aims to eradicate leftover pulp tissue, bacteria, or debris within the canals. The reshaping of the canals is a fundamental step that prepares them for efficient disinfection and the subsequent filling process.

The dentist will employ finely-tuned instruments to adapt the canals into the optimal shape for the successful completion of the treatment. Once the cleaning and reshaping are finalised, the root canals will be rigorously sterilised to eliminate lingering bacteria. This sterilisation step prevents potential reinfection and facilitates proper tooth healing.


Filling and Sealing the Treated Canals

After cleaning, reshaping, and sterilising the root canals, they are filled with a biocompatible gutta-percha material. This rubbery substance seals the canals, effectively blocking any entry for bacteria and safeguarding against future infections. Following this, the dentist will seal the previously made access opening with a permanent filling, or in some cases, a dental crown may be placed for additional strength and protection. Temporary fillings might also be utilised between stages of the procedure or while waiting for the final restoration. While the process may seem complex, it’s a routine practice for a skilled dentist and aims to proficiently treat the cracked tooth and ensure an optimal healing process. Proper care after the treatment and adherence to follow-up appointments can make patients look forward to a smooth recovery and a restored healthy smile.



Treating cracked teeth is paramount for safeguarding oral health and overall well-being. Cracked teeth can precipitate problems ranging from enduring pain and sensitivity to grave infections that may jeopardise adjacent teeth and underlying structures. Awareness of different types of cracks, identifying their causes, and knowing the symptoms that might manifest are critical for prompt dental care. When confronted with a cracked tooth, expeditious root canal treatment becomes essential to conserve the natural tooth and evade the need for removal.
