An intruded tooth after a fall has been pushed upward into its socket and may look shorter than the neighbouring tooth—or seem to have disappeared. This is an urgent dental injury. Do not pull, wiggle or push the tooth back yourself. Arrange a same-day dental assessment because care differs greatly between a baby tooth and a permanent tooth.
What is tooth intrusion?
Tooth intrusion, also called intrusive luxation, occurs when an impact drives a tooth into the jawbone along its long axis. The tooth may be partly visible, unusually short, tilted or completely hidden below the gum. It is often firm rather than loose. Swelling, gum bleeding or tenderness may occur, but the absence of severe pain does not mean the injury is minor.
A tooth that appears missing after trauma may instead be intruded, knocked out or fractured. A dentist may need radiographs to locate it and check the surrounding bone and nearby teeth.
What should you do immediately after a tooth is pushed into the gum?
Keep the child calm and check first for a head or facial injury. If the child lost consciousness, is repeatedly vomiting, has a worsening headache, trouble breathing or swallowing, heavy uncontrolled bleeding, marked facial deformity or unusual drowsiness, seek emergency medical care.
- Do not reposition the tooth. Pulling or pushing it can damage the periodontal ligament, developing adult tooth or jawbone.
- Rinse gently. If the child can rinse safely, use clean water. Do not scrub the injured gum.
- Use a cold compress externally. Place a wrapped cold pack against the outside of the lip or cheek for short intervals to help swelling.
- Offer soft foods. Avoid biting with the injured area and avoid very hot, hard or sharp foods.
- Call a dentist promptly. Same-day assessment is sensible even if the child seems comfortable.
Why does it matter whether it is a baby tooth or permanent tooth?
The same-looking injury can require different management. A primary tooth sits close to the developing permanent successor, while a permanent tooth must be preserved whenever possible. The child’s age alone is not enough to identify the tooth; a dentist considers the eruption pattern, tooth shape and radiographs.
Intruded baby tooth
Never replant or attempt to pull a baby tooth into position at home. Current dental-trauma guidance often favours allowing an intruded primary tooth to re-erupt naturally, followed by careful review. Extraction may be recommended when there are specific clinical concerns, infection, severe displacement or another complication—not simply because every intruded baby tooth must be removed.
Parents should attend follow-up visits because injury to a baby tooth can occasionally affect the developing permanent tooth beneath it. Changes can include enamel marks, altered eruption or shape changes, although many children heal without a serious long-term problem.
Intruded permanent tooth
An intruded permanent tooth needs urgent professional care. The plan depends on how far the tooth moved, whether its root is still developing, the condition of the supporting bone and whether other teeth are injured. A dentist may monitor for spontaneous re-eruption, reposition the tooth orthodontically or reposition it surgically. Some teeth later require root-canal treatment, but this decision depends on pulp and root development rather than being automatic on the first day.
What will the dentist check?
The examination usually includes how and when the fall happened, symptoms of head injury, the child’s bite, gum wounds, tooth mobility and injuries to neighbouring teeth. Dental radiographs can help distinguish intrusion from a missing or fractured tooth and show root development and bone injury.
Tell the dentist about medical conditions, medicines, allergies and tetanus status if the injury involved a contaminated wound. Treatment and pain-relief advice should be age-appropriate and individualized.
How long does an intruded tooth take to come down?
There is no single timetable. Some mildly intruded teeth re-erupt over weeks or months, while others need active repositioning. Root maturity, intrusion depth and healing response all matter. Avoid comparing progress with photographs online; scheduled clinical and radiographic reviews are more reliable.
Why is follow-up important?
Complications can develop after the initial discomfort settles. The dentist may monitor tooth colour, sensation, mobility, gum health, root development and radiographic changes. Possible complications include pulp death, infection, inflammatory root resorption, replacement resorption or tooth ankylosis. Prompt review gives the dental team the best chance to identify these changes early.
Return sooner than planned if swelling increases, fever develops, pus appears, pain worsens, the bite changes or the child cannot eat comfortably.
Common questions parents ask
Will an intruded tooth come back down on its own?
It may. Spontaneous re-eruption is possible, especially in some primary teeth and immature permanent teeth, but it cannot be safely assumed without examination and follow-up.
How urgent is a tooth intrusion injury?
Contact a dentist immediately and arrange same-day assessment where possible. Emergency medical care takes priority when there are signs of serious head or facial injury, uncontrolled bleeding or breathing difficulty.
Can I pull the tooth back into place?
No. Do not pull, push or wiggle an intruded tooth. Professional management depends on whether the tooth is primary or permanent and on the severity of the injury.
What if the tooth seems to have disappeared?
It may be pushed into the socket, knocked out or fractured. Seek urgent assessment. If the child is coughing, choking or having difficulty breathing, call emergency services because inhalation of a tooth or fragment must be considered.
Can an intruded baby tooth damage the adult tooth?
It can sometimes affect the developing permanent successor, but the outcome varies. Appropriate monitoring helps identify enamel changes, altered eruption or other developmental effects.
Key takeaway
An intruded tooth after a fall should be assessed promptly. Protect the area, use a wrapped cold compress externally, give soft foods and do not attempt to reposition the tooth. Correct care begins by identifying whether the injured tooth is primary or permanent.
