What is a Tooth Avulsion? A Complete Guide

Tooth avulsion is a dental emergency that can happen unexpectedly, often leaving individuals in a state of shock and uncertainty. Whether it’s due to a sports injury, an accident, or a fall, the sudden loss of a tooth can be both painful and alarming. 

But what is a tooth avulsion, and how should you respond if it happens to you or someone you know?

Knowing what exactly a tooth avulsion is and understanding what steps to take in the immediate aftermath can enable you to handle an avulsion emergency effectively. 

Let’s find out what the symptoms and signs are after a tooth avulsion and how effective prevention strategies can help you make the best decisions for your dental health. 

What is a Tooth Avulsion?

Tooth avulsion refers to the complete displacement of a tooth from its socket in the jawbone due to trauma or injury. It is a severe dental emergency that requires immediate attention to potentially save the tooth and prevent complications. 

When a tooth is avulsed, the blood vessels and nerves connecting it to the jawbone are usually severed, making prompt and proper handling crucial for successful re-implantation.

Causes of an Avulsed Tooth

An avulsed tooth occurs when a tooth is completely knocked out from its socket in the jawbone. This can happen due to various causes, including:

  • Trauma & Accidents: Trauma to the mouth or face, such as sports injuries, falls, or physical altercations. 
  • Motor Vehicle Accidents: Collisions involving sudden and forceful impact to the face or mouth area.
  • Workplace Injuries: Industrial or construction accidents where blunt force trauma affects the mouth.
  • Home Accidents: Slipping and falling, bumping into furniture or other objects that cause direct impact to the mouth.
  • Biting Forces: Biting down on something extremely hard or a sudden and forceful bite.

Symptoms of an Avulsed Tooth

Visible Displacement of the Tooth

The tooth is completely knocked out of its socket and may be partially or fully visible outside the mouth.

Pain & Discomfort

The tooth avulsion is accompanied by immediate and often intense pain at the site of the injury, especially around the socket area.


Bleeding from the gums or around the tooth socket due to trauma to the blood vessels is another common symptom of an avulsed tooth. 

Looseness or Mobility

The tooth may feel loose or out of place, especially if it has not been completely knocked out and is partially displaced.

Swelling & Tenderness

Your gums may feel swollen and tender in the surrounding soft tissues of the affected tooth.

Difficulty Eating or Speaking

You could also face discomfort or difficulty in using the mouth for normal activities due to pain and injury.

What to Do if a Tooth is Avulsed

Experiencing a tooth avulsion can be distressing, but taking immediate and correct actions can significantly impact the outcome and potential for saving the tooth. 

Here are the steps you need to take in the immediate aftermath of a tooth avulsion. 

  • Remain calm and composed to facilitate clear thinking and effective actions.
  • Handle the tooth carefully and hold it by the crown. Avoid touching the root. 
  • If the tooth is dirty, rinse it gently with milk or saline solution. Do not scrub or remove any tissue fragments attached to the tooth.
  • Ideally, you should try to reposition the avulsed tooth back into its socket immediately if it’s not damaged, and you can do so without force.
  • If you cannot re-implant the tooth immediately, store it properly to maintain its viability. You can either place the tooth in a container of cold milk or a saline solution or cover it in saliva. 
  • Time is critical. Contact an emergency dentist or go to the nearest dental clinic as soon as possible, ideally within 30 minutes to an hour of the avulsion.

Additional Considerations

Avoid Dry Storage: Never store the avulsed tooth in plain water or wrap it in a dry cloth, as this can damage the tooth and reduce the chances of successful replantation.  

Handle with Care: Handle the tooth delicately to avoid further damage to the delicate tissues and cells on the root surface.

Do Not Scrub or Clean Aggressively: Avoid scrubbing or cleaning the tooth vigorously, as this can damage the root surface cells that are essential for successful replantation.

Why Seeking Emergency Dental Care is Essential for a Tooth Avulsion


The success of re-implanting an avulsed tooth significantly decreases with time. Ideally, the tooth should be repositioned back into its socket within 30 minutes to an hour of the injury—every minute counts. 

Preservation of Vital Structures

Prompt re-implantation helps preserve the tooth’s periodontal ligament fibers and root surface cells, which are crucial for the tooth to reattach and receive nourishment from the surrounding tissues. Delayed re-implantation increases the risk of these structures becoming non-viable, reducing the chances of successful replantation.

Prevention of Infection

Avulsed teeth are exposed to potential contaminants from the environment, increasing the risk of infection. Prompt dental care involves thorough cleaning of the tooth and socket to minimize the risk of bacterial growth and infection. 

Long-Term Dental Health & Aesthetics

Saving an avulsed tooth through prompt and effective emergency care preserves natural dentition, maintains oral function, and prevents neighboring teeth from shifting or over-erupting. This helps protect overall dental health and aesthetics, avoiding the need for more invasive and costly dental procedures in the future.

How Can Your Dentist Treat a Tooth Avulsion?

Evaluation & Assessment

Upon arrival, the dentist will conduct a thorough examination to assess the extent of the injury. This includes evaluating the avulsed tooth, the socket, and any surrounding tissues for damage or additional injuries.

Re-Implantation (if possible)

If the tooth is intact and in suitable condition, the dentist will attempt to reposition it back into its original socket. This procedure is ideally performed within 30 minutes to an hour of the avulsion to maximize success.

Stabilization with Splinting

The dentist may use a splint to facilitate healing and stabilize the re-implanted tooth. A splint is a flexible or rigid device that attaches to the avulsed tooth and neighboring teeth, providing support and preventing movement during the initial healing period.

Monitoring & Follow-Up Appointments

After re-implantation, the dentist will closely monitor the tooth’s progress. Follow-up appointments are essential to assess healing, check the stability of the tooth, and make any necessary adjustments to the splint.

Root Canal Treatment (if needed)

Depending on the extent of damage to the tooth’s root and nerve, your dentist may recommend root canal therapy. This procedure removes damaged or infected tissue from inside the tooth to prevent further complications and preserve its structure.

Provisional Restoration

In cases where the avulsed tooth cannot be re-implanted immediately or successfully, your dentist may discuss options for temporary or permanent restoration options, such as dental implants, bridges, or removable dentures.

How Can You Prevent Tooth Avulsion?

  • Use Protective Gear: Wear appropriate mouthguards or helmets during sports and recreational activities where there is a risk of facial injury.
  • Practice Safe Play: Follow rules and guidelines for safe play in sports and recreational activities. Avoid reckless behavior that increases the risk of falls or collisions.
  • Maintain Safe Environments: Ensure that home and workplace environments are free from hazards that could cause falls or accidents leading to facial injuries.
  • Supervise Children: Supervise young children during play to prevent accidents that could result in dental injuries, such as tooth avulsion. 
  • Regular Dental Check-ups: Attend regular dental check-ups to maintain oral health and detect any underlying dental issues that could weaken teeth or increase susceptibility to injury.
  • Emergency Preparedness: Familiarize yourself with basic first aid procedures for dental emergencies, including what to do in the event of a tooth avulsion. 


Understanding what is tooth avulsion can prove crucial for being prepared in the event of a dental emergency.

Whether caused by sports injuries, accidents, or other traumatic events, the complete displacement of a tooth from its socket demands immediate action to save the tooth and minimize complications.

Can an avulsed tooth always be saved?

Ideally, if the tooth is repositioned back into its socket within 30 minutes to an hour of the avulsion, and if the tooth is handled and stored properly, there is a higher chance of successful re-implantation. However, success is not guaranteed in every case. Promptly seeking emergency dental care and following the dentist’s instructions are crucial steps to save the avulsed tooth.

How long does an avulsed tooth take to heal after replantation?

In general, initial healing of the tooth and surrounding tissues usually takes a few weeks. Complete healing and integration of the tooth back into the jawbone can take several months.
