Tooth Knocked Loose But Not Out: What Luxated Teeth Mean and What to Do

A Tooth That Moves When It Shouldn't: Understanding Luxation Injuries

Most people know that a tooth completely knocked out of the mouth is a dental emergency. But what about a tooth that was hit hard, moved from its position, feels loose, looks tilted, or seems to have shifted — but is still in your mouth? This type of injury, called a luxation injury, is also a dental emergency and requires same-day evaluation and treatment.

Luxated teeth are surprisingly common in facial trauma — particularly from sports injuries, falls, car accidents, and physical altercations. The type and severity of the luxation determines the appropriate treatment, but all luxation injuries need to be professionally evaluated the same day they occur.

Types of Tooth Luxation Injuries

Concussion

The tooth received a blow but did not move from its position. It is sore to the touch and sensitive to biting but appears normal in position and mobility. The periodontal ligament has been bruised. Treatment: bite adjustment if needed, soft diet, and monitoring. The tooth usually recovers fully, though pulp vitality needs to be tracked over time.

Subluxation

The tooth has been loosened by the trauma — it moves more than it should when touched — but it remains in its normal position. There may be bleeding from the gumline around the tooth. Treatment: splinting may or may not be needed depending on mobility degree, soft diet, monitoring.

Lateral Luxation

The tooth has been displaced sideways — pushed to the side — out of its normal alignment. It may feel 'locked' in the wrong position because the root tip is now embedded in the bone at a different angle. This is one of the more serious luxation types. Treatment: repositioning the tooth (often requiring forceful manual or instrument manipulation) and splinting.

Extrusive Luxation

The tooth has been partially pulled out of the socket — it appears elongated, higher than surrounding teeth, and is loose. This is the classic 'tooth hanging by a thread' presentation. Treatment: prompt repositioning back into the socket and splinting. Pulp usually dies and requires root canal therapy within a few weeks.

Intrusive Luxation

The most serious luxation type. The tooth has been driven deeper into the socket and into the bone — it appears shorter than its neighbors, may seem to have partially 'disappeared' into the gum, and is tightly locked in the abnormal position. In children with developing permanent teeth, intrusion carries high risk of damage to the developing tooth bud. Treatment depends on tooth type, root development, and extent of intrusion — options include waiting for re-eruption (in young patients with open apices), orthodontic repositioning, or surgical repositioning.

⚠️ Warning: All luxation injuries — every type — require same-day dental evaluation. The classification of the injury can only be accurately determined by a dental professional with clinical examination and X-rays. Do not wait to see if the tooth 'settles' on its own.

What to Do Immediately After a Luxation Injury

1. Do not try to reposition the tooth yourself unless it is an extrusive luxation where the tooth is clearly hanging forward — in that case, gently guide it back toward its normal position with clean fingers and light pressure, then bite on gauze.
2. Control bleeding: Apply gentle pressure with clean gauze to any bleeding around the gum tissue.
3. Take ibuprofen for pain and inflammation.
4. Apply cold compress to outside of cheek.
5. Eat nothing until seen — biting on a luxated tooth can worsen the displacement.

What Happens at American Urgent Dental

When you arrive with a luxation injury, we take a focused trauma history (how the injury happened, when, any loss of consciousness), perform a careful clinical examination, and take periapical and possibly panoramic X-rays to assess the root position, alveolar bone involvement, and relationship to other anatomical structures.

Based on these findings, we determine the appropriate treatment — which may include repositioning the tooth under local anesthesia, splinting it to adjacent teeth for a period of stabilization, and planning for root canal therapy when appropriate. We'll also discuss what monitoring is required over the following weeks and months, since luxated teeth can develop delayed complications including pulp death, root resorption, and ankylosis (fusion of the tooth to the bone).

Long-Term Monitoring After Luxation

Luxation injuries require ongoing monitoring even after the initial emergency treatment, because delayed complications develop over weeks to months:

• Pulp death and periapical abscess: The trauma often damages the blood supply to the pulp, which dies weeks to months after the injury. Signs include tooth darkening and periapical changes on X-ray.
• External root resorption: The body's immune system can attack the root of a reimplanted or repositioned tooth, gradually dissolving the root structure.
• Ankylosis: The tooth fuses directly to the bone instead of being held by the periodontal ligament. Ankylosed teeth in growing children stop erupting while the rest of the dentition continues, creating a submerged tooth. Surgical intervention is needed.
• Alveolar bone loss: Chronic low-grade inflammation around a traumatized tooth can gradually destroy the supporting bone.

We schedule follow-up appointments at 2 weeks, 1 month, 3 months, 6 months, and 1 year after significant luxation injuries. Patients who follow through with this monitoring catch complications early — when they are still manageable — rather than being surprised by tooth loss months or years later.
