A fall — whether on a pavement, during sport, or at home — can happen in an instant, and the dental injuries that result can be both painful and alarming. One of the more distressing types of dental trauma occurs when a tooth is pushed into the gum, sometimes appearing to shorten or even disappear entirely into the socket.
The natural instinct in this situation is often to try to pull the tooth back into position. However, this is something that should never be attempted at home. A tooth that has been forced into the gum — known clinically as a dental intrusion injury — involves damage to the tooth, the surrounding bone, and the supporting tissues, and requires careful professional management.
This guide explains what happens during a tooth intrusion injury, why self-treatment carries significant risks, what you should do immediately after the injury, and how dental professionals approach assessment and treatment — so that if this situation arises, you are equipped to respond safely and calmly.
If a tooth is pushed into the gum (intrusion injury), do not attempt to pull it out yourself. This type of dental trauma requires professional assessment. Keeping the area clean and seeking urgent dental care is important to protect the tooth and surrounding structures.
Key Points:
A tooth intrusion injury occurs when a tooth is driven deeper into its socket by the force of an impact. Rather than being knocked out of the mouth — which is known as avulsion — the tooth is pushed inward, sometimes partially and sometimes to the point where it is barely visible above the gum line.
This type of injury differs from a knocked-out tooth in several important ways. When a tooth is avulsed, it separates entirely from its socket, and the focus is on reimplanting it as quickly as possible. With an intrusion injury, the tooth remains in the socket but has been forced into a position that damages the surrounding bone, the periodontal ligament that holds the tooth in place, and potentially the blood supply and nerve within the tooth itself.
Intrusion injuries are considered among the more complex forms of dental trauma because they involve damage to multiple structures simultaneously. The force required to push a tooth into the bone is substantial, and the resulting injury typically requires careful assessment to determine the extent of the damage and the most appropriate course of action.
When a tooth appears to have been pushed into the gum, the temptation to try to pull it back into its normal position is understandable. However, doing so carries serious risks:
Risk of damaging surrounding tissues: The tooth is held in place by the periodontal ligament and surrounded by bone. Attempting to pull or manipulate the tooth without proper instruments and technique can tear the ligament, fracture the surrounding bone, or cause further injury to the gum tissue.
Increased risk of infection: Handling the area with unclean hands or instruments introduces bacteria into what is already a vulnerable wound site. The tissues around an intruded tooth are damaged and susceptible to infection, and unhygienic intervention can significantly increase this risk.
Potential for further complications: Pulling on an intruded tooth can worsen the damage to the nerve and blood supply within the tooth, reduce the chances of the tooth recovering, and cause additional injury to adjacent teeth and structures. What might have been a manageable injury can become significantly more complex if the area is disturbed inappropriately.
Incorrect force and direction: Dental professionals use specific techniques, instruments, and sometimes orthodontic appliances to reposition intruded teeth in a controlled and gradual manner. The force, direction, and speed of repositioning all matter — and these cannot be replicated safely at home.
The most important thing you can do is leave the tooth undisturbed and seek professional care as soon as possible.
Tooth intrusion injuries can result from any impact that delivers sufficient force to the tooth in a downward or inward direction. The most common causes include:
Falls: Trips and falls are one of the leading causes of dental intrusion, particularly in young children who are still developing coordination and balance. Falls onto hard surfaces such as pavements, floors, or playground equipment can deliver enough force to push a tooth into the gum.
Sports injuries: Contact sports and activities with a risk of facial impact — such as football, rugby, hockey, basketball, and martial arts — account for a significant proportion of dental trauma cases. An elbow, ball, or collision with another player can cause intrusion injuries.
Accidents: Road traffic incidents, cycling accidents, and other accidental impacts to the face or mouth can result in intrusion injuries, sometimes alongside other facial or dental trauma.
In all cases, the severity of the intrusion depends on the force of the impact, the angle at which the tooth was struck, and the individual characteristics of the tooth and surrounding bone.
Recognising a tooth intrusion injury is important so that appropriate action can be taken. Common signs and symptoms include:
If you notice any of these signs following a fall or impact to the mouth, it is important to seek dental assessment promptly, even if the pain seems manageable.
The steps you take in the immediate aftermath of a tooth intrusion injury can help protect the tooth and surrounding structures while you arrange professional care:
Stay calm. While the injury may look alarming, remaining calm allows you to think clearly and take the right actions. Reassure the injured person — particularly if it is a child — and assess the situation.
Do not touch or attempt to move the tooth. This is the most critical piece of advice. Resist any urge to push, pull, or wiggle the tooth. Leave it exactly where it is.
Keep the area clean. Gently rinse the mouth with clean, lukewarm water to remove any blood or debris. Avoid vigorous rinsing, as this can disturb the injured area.
Control any bleeding. Apply gentle pressure with a clean, damp cloth or gauze to any bleeding areas. A cold compress applied to the outside of the face can help manage swelling.
Avoid eating or drinking on the affected side. Until you have been assessed by a dentist, try to avoid putting any pressure on the injured tooth.
Seek dental care urgently. Contact your dental practice as soon as possible and explain what has happened. If the injury occurs outside normal hours, seek emergency dental care.
The treatment approach for an intruded tooth depends on several factors, including the severity of the intrusion, the type of tooth affected (primary or permanent), and the stage of root development:
Assessment and imaging: The first step is a thorough clinical examination, usually accompanied by dental X-rays or other imaging. This allows the dentist to assess how far the tooth has been pushed into the socket, whether the root is intact, and whether there is damage to the surrounding bone.
Monitoring for spontaneous re-eruption: In some cases — particularly in children with developing teeth — the intruded tooth may gradually return to its normal position on its own over a period of weeks. The dentist will monitor the tooth's progress through regular follow-up appointments.
Orthodontic repositioning: If the tooth does not re-erupt on its own, or if the intrusion is more severe, the dentist may use orthodontic techniques to gradually guide the tooth back into its correct position. This controlled, slow repositioning helps minimise further damage to the surrounding structures.
Surgical repositioning: In cases of severe intrusion, it may be necessary to carefully reposition the tooth surgically. This is performed under local anaesthetic and involves gently moving the tooth back to its original position, followed by stabilisation with a splint.
Stabilisation: Once the tooth has been repositioned — whether spontaneously, orthodontically, or surgically — it may be splinted to the adjacent teeth to hold it in place while healing occurs.
Nerve treatment: Because intrusion injuries frequently damage the blood supply and nerve within the tooth, root canal treatment in London may be required at some stage during the recovery process. This involves removing the damaged pulp tissue, cleaning the canal system, and sealing the tooth to prevent infection.
While it is important not to create unnecessary alarm, understanding the potential consequences of leaving an intrusion injury untreated can help reinforce the importance of seeking professional care:
Damage to tooth structure: Without appropriate management, the intruded tooth may not return to its normal position, and the surrounding bone may heal around the tooth in its displaced position, making later treatment more complex.
Infection risk: Damaged tissues are vulnerable to bacterial infection. If the nerve within the tooth has been compromised, infection can develop within the tooth itself and potentially spread to the surrounding bone and tissues.
Long-term effects on oral health: Untreated intrusion injuries can lead to complications such as root resorption — where the body gradually breaks down the root of the tooth — ankylosis, where the tooth fuses to the bone, or loss of the tooth entirely. These outcomes are not inevitable, but they become more likely without timely professional intervention.
Early assessment and appropriate management give the tooth the best opportunity for a favourable outcome.
A tooth intrusion injury should be assessed by a dental professional as soon as possible. Seek urgent care in the following circumstances:
Arranging an emergency dentist appointment in London promptly after dental trauma helps ensure that the injury is assessed thoroughly and that the most appropriate management plan is put in place without unnecessary delay.
Recovery after a tooth intrusion injury is a gradual process that requires patience and ongoing professional monitoring:
Monitoring healing: Your dentist will arrange a series of follow-up appointments to monitor the tooth's response to treatment, check for signs of complications such as infection or root resorption, and assess whether the nerve within the tooth remains healthy.
Possible further treatment: Depending on how the tooth responds, additional treatment may be needed during the recovery period. This could include root canal treatment if the nerve is affected, adjustment of a splint, or further repositioning if the tooth has not moved into the desired position.
Importance of follow-up visits: Attending all scheduled follow-up appointments is essential, even if the tooth feels comfortable and appears to be healing well. Some complications develop gradually and may not produce symptoms in the early stages — regular professional monitoring helps identify any issues early so they can be addressed appropriately.
Recovery timelines vary depending on the severity of the injury and the treatment approach, and your dental team will provide guidance specific to your situation at each stage.
While not all dental injuries can be prevented, there are practical steps that can help reduce the risk:
Protective measures during activities: Wearing a properly fitted mouthguard during contact sports and high-risk physical activities provides significant protection for the teeth and surrounding structures. Custom mouthguards made by a dentist typically offer the best fit and protection.
Safe environments: Ensuring living spaces are free from trip hazards — particularly for young children and older adults who may be more susceptible to falls — can help reduce the risk of accidental dental injuries. Non-slip surfaces, adequate lighting, and secured rugs are simple but effective measures.
Awareness during sports: Understanding the risks associated with your sport and using appropriate protective equipment — including helmets, face guards, and mouthguards where relevant — can help minimise the impact of any accidental contact.
Maintaining oral health: Keeping teeth and gums healthy through regular dental check-ups, good oral hygiene, and professional cleaning can help ensure that teeth are as strong and resilient as possible. Dental hygienist services in London for oral health support your daily routine by professionally managing plaque and tartar, contributing to the overall strength and health of your teeth and gums.
When a tooth is pushed into the gum, it is called a dental intrusion injury. The tooth is forced deeper into its socket, which can damage the surrounding bone, the periodontal ligament, and the nerve and blood supply within the tooth. This type of injury requires professional assessment to determine the extent of the damage and the most appropriate treatment approach.
No. Attempting to pull or reposition a tooth that has been pushed into the gum can cause further damage to the tooth, the surrounding bone, and the gum tissue. It can also increase the risk of infection and reduce the chances of a successful outcome. Leave the tooth undisturbed and seek professional dental care as soon as possible.
A tooth intrusion injury is generally considered to require urgent dental care. While the situation may not always be life-threatening, prompt professional assessment is important to evaluate the extent of the injury and to begin appropriate management. Contacting your dental practice or seeking emergency dental care as soon as possible after the injury is advisable.
The outcome depends on several factors, including the severity of the intrusion, the type of tooth affected, whether the root is still developing, and how quickly professional care is received. In many cases, appropriate management can preserve the tooth, though long-term monitoring is usually required. Your dentist will provide an honest assessment based on the specific circumstances of the injury.
Stay calm, do not attempt to move or manipulate any displaced teeth, and keep the area clean by gently rinsing with lukewarm water. Control any bleeding with gentle pressure using a clean cloth, apply a cold compress to the outside of the face to manage swelling, and seek professional dental care as soon as possible.
