Knocked-Out Tooth — Emergency Dental Care in Sandgate
A knocked-out adult tooth is one of the few situations in dentistry where what you do in the first 30 minutes really matters. At Sandgate Family Dental we keep urgent appointments available each day so we can see you quickly and give the tooth the best possible chance.
If a permanent tooth has just been knocked out, follow the first-aid steps below and call the practice on your way in, or book an urgent appointment online. We see patients from Sandgate, Brighton, Shorncliffe, Bracken Ridge, and the surrounding northern Brisbane suburbs.

First-aid steps in the first 30 minutes
Time is the single most important factor with an avulsed (knocked-out) adult tooth. The sooner the tooth is back in the socket — or stored correctly — the better the outlook.
If you are not sure whether your situation needs urgent care, our guide on how to tell if it is a dental emergency may help.

Why time matters so much
When a tooth is knocked out, the cells on the root surface begin to lose viability within minutes of being outside the mouth. Keeping those cells alive — by replanting the tooth or storing it in milk — gives a replanted tooth a better chance of healing back into the bone.
Replantation is not always possible, and even when a tooth is successfully replanted, follow-up treatment is usually needed. The aim of urgent care is to give your dentist the best chance of saving the tooth and to manage any other injuries to the mouth at the same time.

Common causes of knocked-out teeth
Most avulsed teeth in our patients come from one of the following:
Where sport is involved, a properly fitted custom sports mouthguard can reduce the risk of dental injury. Our team also has information on sports-related dental injuries and what to do at the side of the field.

What happens when you arrive at the practice
Our priority when you arrive is to settle you in, ease any pain or anxiety, and assess what has happened.
1. A gentle assessment
We will ask how the injury happened, how long the tooth has been out of the mouth, and how it has been stored. We will check for other injuries to the lips, gums, and jaw.
2. Imaging
Small digital X-rays help us see whether the socket and surrounding bone are intact, and whether any nearby teeth have been affected.
3. Replanting and splinting
If the tooth is suitable for replantation, your dentist will carefully position it back into the socket and stabilise it with a small splint bonded to the neighbouring teeth. The splint usually stays in place for one to two weeks.
4. Care for the surrounding tissues
Any cuts to the gum, lip, or tongue will be cleaned and managed. We will also discuss whether antibiotics or a tetanus check are appropriate, depending on the circumstances. If you have other oral injuries, our information on soft tissue injuries may be relevant.
5. A clear follow-up plan
Most replanted teeth need a root canal treatment in the weeks following replantation, and ongoing reviews to monitor healing. We will explain the plan and costs in plain terms before any treatment goes ahead.

If the tooth cannot be saved
Sometimes a knocked-out tooth cannot be replanted — for example, if too much time has passed, if it has been stored dry, or if the socket has been damaged. In those situations our focus shifts to managing the area comfortably and discussing tooth replacement options.
Common options to replace a missing tooth include:
- Dental implants — a long-term replacement that does not rely on the neighbouring teeth
- Dental bridges — a fixed restoration supported by the teeth on either side
- A removable partial denture for shorter-term or budget-conscious situations
You do not need to decide on a replacement at the urgent visit. Our role on day one is to settle the immediate problem; replacement options are discussed once the area has healed.

If it happens outside of business hours
If a tooth is knocked out in the evening or on a weekend, follow the first-aid steps above and head to your nearest dental or hospital emergency service straight away. Our information on after-hours dental care explains what to do until you can be seen, and we will see you for follow-up at our practice as soon as possible.
Payment
Health funds and payment
We are a HICAPS provider, so where you have eligible dental cover we can process your health fund claim at the practice and you only need to pay any gap.
The exact rebate you receive depends on your individual policy, your level of cover, and your annual limits — your fund can confirm what is covered before treatment. We can provide an itemised treatment plan with item numbers so you can check your entitlements in advance, and we are happy to discuss payment plan options for any larger follow-up treatment.
FAQs
Knocked-out tooth FAQs
How long do I have to save a knocked-out tooth?
The first 30 to 60 minutes are the most important. Replantation can sometimes still be attempted after that, but the chance of long-term success drops as time passes — and as the root surface dries out.
Should I put the tooth back in myself?
If it is an adult (permanent) tooth and you feel able to, yes — gently place it back into the socket the right way around and bite softly on a clean cloth to hold it in place. If you are unsure, store the tooth in cold milk and head straight to the dentist. Do not attempt to replant a baby tooth.
What if the tooth is dirty?
Rinse it briefly in cold milk or saline, holding it by the crown only. Do not scrub it, do not use soap or disinfectant, and do not let it dry out.
Can a knocked-out tooth always be saved?
No. Outcomes depend on how the tooth was stored, how long it was out of the mouth, the age of the patient, and the condition of the socket. Your dentist will give you a realistic picture once they have assessed the tooth.
What if my child’s adult tooth is knocked out at school or sport?
Ask whoever is with them to keep the tooth in cold milk and contact a parent or carer. If safe to replant, that can happen at the side of the field — otherwise come straight to a dentist.
Will I need a root canal afterwards?
Most replanted adult teeth need root canal treatment within the first few weeks because the nerve does not usually survive the injury. Your dentist will explain when this is needed.
