The Causes of Root Resorption and its Endodontic Remedies

Root resorption is a dental condition that occurs when the body’s natural processes cause the loss of tooth root structure. It can be a concerning problem as it can lead to the weakening and potential loss of teeth if left untreated. we will explore the various causes of root resorption and the endodontic remedies available to address this condition. Root resorption is the progressive loss of dental root structure, where the body absorbs the root material. The roots of our teeth play a crucial role in anchoring them to the jawbone and providing stability for biting and chewing. When root resorption occurs, it can compromise the structural integrity of the tooth and pose significant oral health challenges. Maintaining the health of our roots is essential for preserving our teeth and preventing tooth loss. Let’s delve into the causes of root resorption and the remedies available to tackle this issue effectively.

Types of Root Resorption

Root resorption can be classified into two main types: external root resorption and internal root resorption.

External Root Resorption

External root resorption occurs when the resorption process affects the outer surface of the tooth’s root. It can manifest in two different forms: surface resorption and replacement resorption.

Surface Resorption
Surface resorption involves the breakdown of the root’s surface without invading the inner root structure. It can be caused by factors such as excessive orthodontic force, trauma, or chronic inflammation. Surface resorption can be detected early through regular dental examinations and treated accordingly.

Replacement Resorption
Replacement resorption, also known as ankylosis, is a condition where the root is replaced by bone tissue. It can occur due to severe trauma or chronic inflammation. Replacement resorption can result in the loss of the tooth if not addressed promptly.

Internal Root Resorption

Internal root resorption takes place within the root canal system, involving the destruction of the tooth’s internal structure. This type of resorption can be categorized into two forms: inflammatory root resorption and replacement resorption.

Inflammatory Root Resorption
Inflammatory root resorption occurs when there is inflammation within the root canal system, leading to the resorption of the tooth structure. It can be caused by factors such as dental infections, trauma, or dental procedures. Early diagnosis and appropriate endodontic treatment can help manage inflammatory root resorption effectively.

Replacement Resorption
Similar to external root resorption, replacement resorption within the root canal system involves the replacement of the tooth’s internal structure with bone tissue. This form of resorption can be challenging to treat and may require surgical intervention.

Causes of Root Resorption

Several factors can contribute to the development of root resorption. Understanding the underlying causes can help prevent or manage this condition effectively. The following are some common causes of root resorption:


Trauma to the teeth, such as a blow to the mouth or facial injuries, can lead to root resorption. The force exerted on the teeth during an accident or sports-related injury can disrupt the blood supply to the roots, triggering the resorption process.

Orthodontic Treatment

Orthodontic treatment, while beneficial for correcting dental misalignments, can sometimes induce root resorption. The application of excessive force or prolonged pressure on the teeth during orthodontic procedures can cause the roots to undergo resorption.

Dental Infections

Untreated dental infections, such as tooth decay or periodontal disease, can result in root resorption. Infections can lead to inflammation within the root canal system, initiating the resorption process. Prompt treatment of dental infections is vital to prevent further damage.


Genetic factors can also play a role in root resorption. Certain individuals may be more predisposed to develop this condition due to their genetic makeup. Understanding family dental history and regular check-ups can help identify potential risks early on.

Achieving a brighter smile through teeth whitening can be a game-changer, but it’s vital to prioritize your dental health and avoid potential pitfalls. At Gorgeous Smiles Dental, we emphasize the importance of removing harsh DIY methods, overusing whitening products, and neglecting proper dental hygiene. By choosing professional teeth whitening treatments or exploring natural remedies under the guidance of our experienced team, you can attain optimal results while minimizing any risks involved. Remember, maintaining excellent oral hygiene practices and seeking personalized advice from our dental experts will ensure a stunning smile you can confidently flaunt.

Symptoms and Diagnosis

Root resorption may not always present noticeable symptoms in its early stages. However, as the condition progresses, the following signs may become evident:

  • Sensitivity to hot or cold substances
  • Tooth mobility or looseness
  • Discoloration or darkening of the affected tooth
  • Swelling or tenderness in the gums surrounding the affected tooth

If root resorption is suspected, a dentist will perform a comprehensive examination, including dental X-rays and possibly a cone beam computed tomography (CBCT) scan. These diagnostic methods help visualize the extent of root resorption and determine the appropriate course of treatment.

Endodontic Remedies for Root Resorption

When it comes to addressing root resorption, various endodontic remedies can be employed based on the type and severity of the resorption. The following are two primary treatment approaches:

Non-surgical Root Canal Treatment

Non-surgical root canal treatment, also known as endodontic therapy, is commonly used to manage root resorption. The procedure involves removing the infected or damaged pulp from the tooth’s root canal system, disinfecting the area, and sealing it to prevent further infection. This treatment aims to halt the resorption process and save the affected tooth.

Surgical Intervention

In some cases, surgical intervention may be necessary to manage severe or complex root resorption. This typically involves accessing the root through a surgical procedure and removing the affected tissue. Surgical intervention can help preserve the tooth or, if necessary, facilitate its extraction and replacement with a dental implant.

Prevention of Root Resorption

While root resorption can occur due to various factors, taking preventive measures can help minimize the risk. Here are some key preventive strategies:

  • Maintain good oral hygiene by brushing twice a day, flossing regularly, and using mouthwash.
  • Attend regular dental check-ups to detect and address any early signs of resorption.
  • Wear appropriate mouthguards during sports or physical activities to protect the teeth from trauma.
  • Seek timely treatment for dental infections or injuries to minimize the potential for resorption.

By adopting these preventive measures and practicing good oral care habits, individuals can reduce the likelihood of root resorption and maintain optimal dental health.
