Dental Trauma

Dental trauma management in London, Ontario

Dental trauma requires prompt assessment and appropriate clinical management. At 562 endodontics, our doctors accept same-day emergency referrals for dental injuries. 

Immediate management is important for diagnosis, stabilization, and follow-up planning. We welcome urgent referrals from dentists in London and Middlesex County.

Classification of traumatic dental injuries and endodontic relevance

Not all dental trauma requires immediate endodontic treatment. However, many injuries require close monitoring, as pulp necrosis and inflammatory root resorption may develop weeks or months after the initial injury.

We encourage dentists to follow the recommended guidelines established by the International Association of Dental Traumatology. 

The following classification summarizes common traumatic dental injuries and their endodontic implications.

Injury type
Endodontic relevance
Referral urgency
Concussion
Low risk of pulp necrosis (~3%). No displacement
Consider a referral to rule out a root fracture.
Subluxation
Possible periodontal ligament injury. Necrosis risk ~6%
Consider a referral to rule out a root fracture.
Extrusive luxation
Necrosis risk ~26% in mature teeth
Same-day referral recommended
Lateral luxation
Necrosis risk up to 58% in mature teeth
Same-day or within 24 hours
Intrusive luxation
Highest severity injury. Necrosis risk up to 96%
Immediate referral
Root fracture
The endodontic prognosis depends on the location of the fracture.
Refer within 24–48 hours
Alveolar fracture
Maxillary, mandibular fracture with multiple teeth involved
Same-day referral recommended to a hospital.

Early evaluation supports timely diagnosis and treatment planning.

Patient guide: Immediate Management of Dental Trauma

Dental injuries require prompt attention to maximize the chance of saving the tooth and preventing long-term problems.

Tooth Fractures web

Tooth Fractures

If a tooth chips or breaks, save any pieces and bring them with the patient.

Tooth Luxation Displacement web

Tooth Luxation (Displacement)

A tooth that is pushed out of place, loose, or knocked sideways should be examined immediately by a dentist.

Tooth Avulsion Knocked Out Tooth web

Tooth Avulsion (Knocked-Out Tooth)

A tooth that is completely knocked out is a serious injury. The faster it is treated, the better the chance of being saved.

Tooth Avulsion (Knocked-Out Tooth)

Recommended storage options (best to worst):

Important: Avoid water if possible — it can damage the cells that help the tooth reattach.

Doctors Guide:

Clinical Protocol and Co-Management
Instructions to relay to a parent or patient calling your office

Instruct the patient to handle the tooth by the crown only if possible. If contaminated, briefly rinse the tooth under cool running water without scrubbing the root surface.

If possible, gently reposition the tooth into the socket and stabilize it by biting on gauze. If this is not possible, place the tooth in cold milk and seek immediate dental care.

We can provide phone guidance for avulsion emergencies as the patient travels to the clinic

Luxation injuries and splinting protocol

We place and remove all splints at 562 endodontics. Splint type and duration depend on the type of injury. The table below outlines IADT 2020 durations and clinical notes for co-management.

Injury
Endodontic relevance
Subluxation
Up to 2 weeks if mobility is present
Extrusive luxation
4 weeks
Lateral luxation
4 weeks
Intrusive luxation
4–8 weeks, depending on severity
Root fracture
4 weeks
Cervical root fracture
Up to 4 months
Avulsion
2 weeks
Alveolar fracture
4 weeks

Horizontal root fractures and the role of CBCT imaging

Horizontal root fractures are often missed on conventional periapical radiographs if the X-ray beam is not aligned with the fracture plane. 

Early CBCT evaluation improves diagnostic accuracy and reduces the risk of missed cervical root fractures, which may otherwise require extraction.

Delayed trauma sequelae

After a dental injury, certain changes in the teeth or surrounding tissues can happen over time. These may need to be checked regularly by both the family dentist and our team at 562 endodontics to ensure everything stays healthy.

01 Pulp canal obliteration

Pulp canal obliteration

This condition presents as a narrowed pulp chamber and yellow discoloration of the crown. Most teeth remain asymptomatic.

02 Internal inflammatory resorption

Internal inflammatory resorption

This appears as a balloon-shaped enlargement of the pulp space on radiographs. 

03 External cervical resorption

External cervical resorption

Progressive loss of tooth structure at the cervical region, often presenting radiographically as a ‘moth-eaten’ radiolucency. Early detection and monitoring are critical to prevent extensive structural compromise.

04 External replacement resorption ankylosis

External replacement resorption (ankylosis)

This condition results in fusion between the tooth and the surrounding bone. The periodontal ligament space disappears on radiographs, and a metallic percussion sound may be detected clinically.

Frequently asked questions

How quickly can 562 endodontics see a trauma emergency?

Same-day appointments are available for acute trauma. Call (519) 601-3636. For avulsion cases, our team provides phone guidance to patients during transit to our office.

Yes. The consultation fee includes a CBCT scan, which is particularly valuable in trauma cases where 2D imaging may miss root fractures or underestimate the extent of injury.

Yes. Infection may develop months or even years after the initial injury. Referral is advised if symptoms or radiographic changes appear.

Yes. Treatment options include vital pulp therapy, regenerative endodontic procedures, and apexification for teeth with open apices.
