Dental Avulsion

Q: What is the very first thing I should do if my tooth is knocked out?

Permanent (adult) tooth: Hold the tooth by the white crown, not the root. Do not scrape, rub or scrub it. If it is dirty, rinse it gently in milk or contact lens saline. If the person is conscious and cooperative, gently place the permanent tooth back in the socket and have them bite on a clean cloth to hold it in place. If you cannot reinsert it, keep it moist in a container of milk or contact lens saline. Seek immediate dental treatment because time is critical.Baby (primary) tooth: Do not put a baby tooth back in the socket. Reimplanting a baby tooth can damage the developing permanent tooth. Seek prompt dental treatment and take the tooth with you.If you are unsure whether it is a baby or permanent tooth: Do not try to reinsert it. Keep it moist in milk or contact lens saline, take it with you and seek urgent dental advice.Reference: Queensland Government, Emergency dental - knocked-out tooth guidance.

Dental Avulsion: Emergency Care You Can Trust in Brisbane

A knocked-out tooth is one of the most urgent dental emergencies. The first few minutes after an injury can decide whether your natural tooth can be saved or needs to be replaced.

At Dental Nook in Brisbane, our emergency dentist is experienced in managing dental avulsion and other dental trauma. We provide prompt, compassionate care for patients from Brisbane.

What Is Dental Avulsion?

Dental avulsion is the complete displacement of a tooth from its socket. It commonly occurs after:

Because the tooth has been pushed out of the socket, the blood supply and supporting tissues are disrupted. Fast and correct first aid gives the tooth the best chance to survive.

Can a Knocked-Out Tooth Be Saved?

In many cases, an avulsed permanent tooth can be replanted successfully. Keeping your own tooth is usually better than replacing it with an artificial alternative, provided the tooth and surrounding tissues are suitable.

Your chances improve when:

You reach a dentist within about sixty minutes
The tooth is handled gently and kept moist
The root surface is not scrubbed or allowed to dry out

Even if more time has passed, it is still worth bringing the tooth to our clinic. Our team will always attempt the most appropriate treatment for your situation.

First Aid for a Knocked-Out Tooth

What To Do Before You Reach Dental Nook

1

Pick up the tooth correctly

Hold the tooth by the crown, which is the white part you normally see in the mouth. Avoid touching the root.

2

Rinse very gently if needed

If the tooth is dirty, give it a quick rinse with milk or with your own saliva. Do not use tap water, disinfectants or soaps and do not scrub the root.

3

Reinsert a permanent (adult) tooth only

Permanent (adult) tooth: Hold the tooth by the white crown, not the root. Do not scrape, rub or scrub it. If it is dirty, rinse it gently in milk or contact lens saline. If the person is conscious and cooperative, gently place the permanent tooth back in the socket and have them bite on a clean cloth to hold it in place. If you cannot reinsert it, keep it moist in a container of milk or contact lens saline. Seek immediate dental treatment because time is critical.

Baby (primary) tooth: Do not put a baby tooth back in the socket. Reimplanting a baby tooth can damage the developing permanent tooth. Seek prompt dental treatment and take the tooth with you.

If you are unsure whether it is a baby or permanent tooth: Do not try to reinsert it. Keep it moist in milk or contact lens saline, take it with you and seek urgent dental advice.

Keep the tooth moist if reinsertion is not possible

If you cannot reposition the tooth:

Place it in a small container of milk, or
Ask the patient to hold it in the side of the mouth between the cheek and gum if it is safe to do so

Never store the tooth dry and do not wrap it in tissue or cloth.

How Dental Nook Treats Dental Avulsion?

When you arrive at Dental Nook Brisbane, our emergency dentist will act quickly to care for both you and your tooth.

You can expect:

1. Immediate assessment

We examine the injured area, check for other damage and confirm whether the tooth is suitable for replanting.

2. Cleaning and preparing the socket

The socket and surrounding tissues are gently cleaned to remove blood clots or debris

3. Reimplantation of the tooth

The tooth is carefully repositioned in the socket. Once the correct position is confirmed, we stabilise it using a small splint that links the injured tooth to the neighbouring teeth.

4. X-rays and imaging

Radiographs are taken to check the position of the tooth and to look for any fractures of the root or jawbone.

5. Pain relief and medication

Local anaesthetic is used when needed. Antibiotics and a tetanus review may be recommended depending on the nature of the injury.

6. Follow-up planning

In most cases, a root canal treatment is required within one to two weeks to protect the tooth from infection and to improve long-term success. Further reviews are scheduled to monitor healing and splint stability.

If the tooth cannot be saved, we will discuss suitable replacement options such as a bridge, partial denture or dental implant once healing is complete.

Aftercare for an Avulsed Tooth

Good aftercare is essential for healing and the long-term survival of the replanted tooth.

We usually recommend:

Avoiding contact sports or rough activities until the dentist confirms healing
Eating a soft diet and chewing on the opposite side for the first few weeks
Keeping the area clean with gentle tooth brushing and rinsing after meals
Using any prescribed chlorhexidine mouthwash as directed to reduce infection risk
Taking pain relief and antibiotics exactly as advised
Attending all review and root canal appointments

Please contact us straight away if you notice increasing pain, swelling, mobility of the splinted tooth or any signs of infection.

Dental Avulsion in Children

Dental injuries are very common in children. Management is slightly different depending on whether the knocked-out tooth is a baby tooth or a permanent tooth.Dental avulsion is the complete displacement of a tooth from its socket. It commonly occurs after:

Baby teeth are usually not replanted because doing so may harm the developing adult tooth underneath. However, prompt assessment is still important to check for other injuries and to plan future space management if required.
Permanent teeth often can and should be replanted as quickly as possible.

If your child has had a tooth knocked out, call Dental Nook immediately. Our team will advise you on first aid and arrange an urgent appointment.

When to See an Emergency Dentist?

You should seek emergency care at Dental Nook if:

A tooth has been completely knocked out
A tooth feels very loose after trauma
Part of the tooth has broken, off and the pulp is visible or very sensitive
There is significant bleeding, swelling or difficulty closing the mouth
You suspect the jaw may be fractured

Even if pain is mild, avulsion and other traumatic dental injuries always require urgent professional assessment.

Frequently Asked Questions about Dental Hygiene

What is the very first thing I should do if my tooth is knocked out?

Baby (primary) tooth: Do not put a baby tooth back in the socket. Reimplanting a baby tooth can damage the developing permanent tooth. Seek prompt dental treatment and take the tooth with you.

If you are unsure whether it is a baby or permanent tooth: Do not try to reinsert it. Keep it moist in milk or contact lens saline, take it with you and seek urgent dental advice.

Reference: Queensland Government, Emergency dental – knocked-out tooth guidance.

How long do I have to save a knocked-out tooth?

The best chance of success is when you see a dentist within about sixty minutes of the injury. The earlier you arrive, the better the outlook for the tooth.

Can children’s knocked-out teeth be replanted?

Permanent teeth in children and teenagers can often be reimplanted. Baby teeth are usually not placed back into the socket because this may harm the developing adult tooth. Our dentist will assess your child and explain the safest approach.

Do I really need an emergency dentist if the tooth is not painful?

Yes. A tooth that has been completely knocked out is always an emergency, even if there is little or no pain. Rapid treatment is needed to reimplant the tooth and to protect the bone, gums and neighbouring teeth.

What if the tooth was stored dry or in tissue?

You should still bring the tooth and any fragments to your appointment. Although the success rate is lower when the tooth has dried out, our dentist will always assess the situation and provide the best possible care.

Will I need a root canal after the tooth is replanted?

In most cases, a root canal treatment is recommended within one to two weeks after reimplantation to help the tooth survive long term and to reduce the risk of infection. Your dentist will discuss this with you during your follow-up visit.

What if I cannot find the knocked-out tooth?

You should still attend urgently. We will check for other injuries, treat any pain or bleeding and discuss replacement options. In some cases, the tooth may be pushed into the gum or lips rather than fully lost, so an examination and X-ray are important.
