Tooth Luxation
Tooth luxation (tooth dislocation) happens when the tissues, ligaments and bones that support a tooth become damaged. Dental trauma and infection can cause it. Symptoms vary depending on the type of tooth luxation. In many cases, treatment can stabilize your tooth and reduce your risk for future issues.
Overview
What is tooth luxation?
Tooth luxation (tooth dislocation) happens when infection (like gum disease) or trauma (like a fall) disrupts the tissues, ligaments and bones that hold a tooth in place. It can also affect your tooth’s nerves and blood supply, leading to pulp damage.
Your teeth sit within the alveolar bone, the part of your jaw that contains your tooth sockets. Connective tissue fibers called periodontal ligaments attach the root of each tooth to your alveolar bone. Tooth luxation can affect all these structures.
No matter what causes it, tooth luxation can seriously impact your ability to eat and speak. It also leaves the door open for bacteria to invade the nooks and crannies around your tooth. There are treatment options that can help stabilize your tooth and keep your pulp healthy.
Types of tooth luxation
Tooth luxation can range from mild to serious. The five types of luxated teeth, in order of severity, are:
| Luxation type | Extent of damage | Tooth positioning | Telltale signs/symptoms |
|---|---|---|---|
| Concussion | Injury to periodontal tissues (the structures that support your tooth) | Tooth hasn’t moved | Feels tender to the touch |
| Subluxation | Injury to periodontal tissues | Tooth is loose but hasn’t moved from original location | Feels tender to the touch; bleeding |
| Extrusive luxation | Periodontal ligaments separate | Tooth has moved out of its socket, but the socket is still intact | Tooth is loose; looks longer than usual |
| Lateral luxation | Your alveolar bone (the bone that holds your teeth) fractures and periodontal ligaments separate | Tooth isn’t loose but looks angled either forward or backward from your gumline | Your provider hears a high-pitched metallic (ankylotic) sound when they tap your tooth |
| Intrusive luxation | Your alveolar bone fractures | Tooth moves up into its socket | Your provider hears an ankylotic sound when tapping your tooth |

How common is tooth luxation?
Anyone can have tooth luxation, but it’s most common in children and young adults. In the United States:
- Luxation of permanent (adult) teeth makes up 18% to 33% of all dental injuries.
- Luxation of primary (baby) teeth makes up 21% to 81% of all dental injuries.
Symptoms and Causes
What are the symptoms of a luxated tooth?
A luxated tooth might be loose, angled or move out of the socket. In some cases, you might have tenderness, but no visible signs.
Luxated tooth symptoms may include:
What causes tooth luxation?
Dental trauma is the most common cause of tooth luxation, including:
- Bicycle accidents
- Car accidents
- Sports injuries
- Violent assaults
Other causes of tooth luxation include:
- Tooth decay
- Gum disease
Complications of tooth luxation
Possible complications of tooth luxation include:
- Ankylosis. This is when your tooth fuses to the bone and starts sinking into your gum tissue.
- Apical periodontitis. This is inflammation that starts around your tooth’s root tip.
- Inflammatory root resorption.This is a breakdown of your tooth’s root structure, which can cause your tooth to loosen
- Pulp canal obliteration (PCO). This involves hard tissue deposits along the walls of the root canal. PCO is usually painless but can lead to pulp necrosis (tissue death).
- Pulp necrosis. This happens when your tooth pulp dies. If you have pulp necrosis, your dentist may need to extract the whole tooth.
Diagnosis and Tests
How is tooth luxation diagnosed?
To diagnose a luxated tooth, a dentist will ask about your symptoms and prior injuries. They’ll also do a physical examination.
During the exam, your dentist will:
- Check your tooth for any mobility (looseness).
- Do a pulp sensibility test to see whether there’s damage to the pulp.
- See whether your tooth is sensitive or tender to the touch.
- Take X-rays of your teeth.
- Tap your tooth to listen for high-pitched, metallic (ankylotic) sounds.
Management and Treatment
How is tooth luxation treated?
The goal of tooth luxation treatment is to stabilize your tooth and keep the pulp healthy. Depending on the type and severity of luxation, your dentist may:
- Apply calcium hydroxide to prevent inflammation inside your tooth
- Check the health of your tooth pulp during regular checkups
- Do a root canal and place a dental crown
- Reposition your tooth
- Splint teeth together for stability (this typically takes two to four weeks, depending on the type of luxation you have)
Outlook / Prognosis
What’s the outlook for tooth luxation?
Prompt treatment can save a luxated tooth in many cases, and it may serve you for many years. But providers can’t predict or guarantee how long your tooth might last.
If you have severe damage, your dentist may recommend removing your tooth and replacing it with a bridge or dental implant. Your dentist can help you weigh your treatment options.
Prevention
Can tooth luxation be prevented?
In many cases, tooth luxation results from accidental trauma — and you can’t always prevent that. But there are steps you can take to lower your risk:
- Wear a seatbelt when in a vehicle.
- Wear a helmet when skating or riding a bike.
- Wear a mouth guard if you play contact sports.
To reduce your risk of infection-related tooth luxation:
- Practice good oral hygiene.
- Visit your dentist for regular exams and cleanings.
Living With
How do I take care of myself?
To help protect your tooth after luxation repair, you should:
- Brush gently with a soft toothbrush after each meal
- Eat soft foods for one week
- Rinse with an antibacterial mouthwash two times a day for one week
- Take NSAIDs as needed for pain relief
- Visit your dentist for regular checkups
When should I see my dentist?
After tooth luxation treatment, tell your dentist if you develop any new or worsening symptoms like tooth discoloration or continued pain, bleeding or swelling.
Additional Common Questions
What’s the difference between luxation and avulsion?
Tooth luxation and avulsion are different types of dental damage. Tooth luxation happens when the tissues and ligaments that hold your tooth in its socket become damaged. Avulsion refers to a completely knocked-out tooth. In other words, your tooth is no longer in its socket.
A note from Wockr
Chances are, you don’t think much about your teeth until something happens to one of them. Maybe someone bumped you in the mouth during softball practice. Or maybe you fell off a ladder and hit your tooth on the way down.
Now, you can’t eat or speak without being aware of your new injury. Tooth luxation doesn’t always require treatment — but it does require immediate medical attention. The sooner you get a dental evaluation, the better your chances of saving your tooth.
