A knocked-out tooth (avulsed tooth) is a dental emergency requiring treatment within 30 minutes. The periodontal ligament cells on the root surface die rapidly once the tooth leaves the socket. Taree Dental Care provides same-day emergency appointments for dental avulsion. Call (02) 6550 0960 immediately and bring the tooth with you.
According to the International Association of Dental Traumatology guidelines updated in 2020, approximately 5 million teeth are avulsed annually in the United States alone, with comparable per-capita rates in Australia. Sports injuries, falls, and bicycle accidents account for 39% of all dental avulsions. Timely action determines whether the natural tooth survives or requires extraction and replacement.
Dr Daniel Kim (BDent, University of Sydney, 2009) and Dr Daniel Lim (BDS, University of Adelaide) lead the emergency dental team at Taree Dental Care. Six dentists with over 50 years of combined clinical experience treat dental trauma at 26 Albert Street, Taree. This page covers every step for handling a knocked-out tooth, from the first 30 minutes through to long-term replacement options.
What Should You Do in the First 30 Minutes After a Tooth Is Knocked Out?
The first 30 minutes after avulsion determine whether the tooth survives. Periodontal ligament cells on the root surface begin dying within 15 minutes of dry exposure. A tooth reimplanted within 30 minutes has a 90% survival rate. After 60 minutes, the survival rate drops to 75%. Every minute of delay reduces the chance of successful reimplantation.
Follow these 6 steps immediately after a tooth is knocked out:
- Find the tooth immediately. Search the area where the injury occurred. Time spent searching reduces cell viability on the root surface.
- Pick up the tooth by the crown only. The crown is the white, visible part of the tooth. Never touch the root. Touching the root damages the periodontal ligament cells needed for reattachment.
- Rinse the tooth gently for 5 seconds. Use milk, saline, or saliva. Do not scrub, scrape, or brush the root surface. Do not use antiseptic, alcohol, or soap. Rinsing removes dirt without destroying root cells.
- Try to reinsert the tooth into the socket. Push it gently into the correct position, matching the original angle and orientation. Bite down firmly on a clean handkerchief, gauze, or tissue to hold the tooth in place.
- Store the tooth if reinsertion is not possible. Place the tooth in milk, saline, or saliva (inside the cheek for adults only). Do not store the tooth in water. Water causes osmotic shock and kills root cells within minutes.
- Call (02) 6550 0960 and get to Taree Dental Care immediately. Inform the receptionist of the dental avulsion. Same-day emergency appointments are available. Bring the stored tooth with you.
The 30-minute window is not a guideline. Cells on an avulsed tooth root undergo irreversible necrosis after 60 minutes of dry time. Patients who act within the first 30 minutes give dentists the best possible chance of saving the natural tooth without long-term complications. Our emergency dental care page details every urgent dental condition treated at Taree Dental Care.
How Do You Handle and Store a Knocked-Out Tooth?
Handle a knocked-out tooth by the crown only and store it in cold, full-fat milk to maximise cell survival. The periodontal ligament cells covering the root are fragile. Physical contact, drying, and incorrect storage media destroy these cells, making reimplantation impossible.
Handling Rules
Pick up the tooth by the chewing surface (the crown). Do not touch, hold, or grip the root. Do not remove tissue fragments attached to the root. Do not scrub, scrape, or wipe the root surface. These tissue fragments contain viable cells essential for reattachment to the jawbone.
Storage Media Ranked by Effectiveness
Different storage liquids preserve root cells with varying success rates. The table below ranks storage media by their ability to maintain periodontal ligament cell viability over time.
| Rank | Storage Medium | Cell Viability Duration | Availability |
|---|---|---|---|
| 1 | HBSS (Hanks Balanced Salt Solution) | 24+ hours | Dental practices, pharmacies (rarely available publicly) |
| 2 | Milk (cold, full-fat) | Up to 6 hours | Supermarkets, service stations, home |
| 3 | Saline (0.9% sodium chloride) | Up to 2 hours | Pharmacies, first aid kits |
| 4 | Saliva (inside cheek or container) | Up to 2 hours | Always available for adults |
| 5 | Cling film (plastic wrap) | Up to 1 hour (prevents drying only) | Most kitchens, shops |
| 6 | Water | Cell death within 10 minutes | Avoid entirely |
Milk is the best practical storage option for most patients. Cold full-fat milk maintains cell viability for up to 6 hours because its pH and osmolarity closely match human body fluid. The calcium and phosphate ions in milk also nourish root cells during transport.
Why Water Damages Root Cells
Water causes osmotic shock. Root cells have a specific internal salt concentration. Plain water has zero salt concentration. Water rushes into root cells by osmosis, causing them to swell and rupture within 10 minutes. A tooth stored in water for 20 minutes has the same prognosis as a tooth left dry on the ground.
When No Storage Medium Is Available
Wrap the tooth in cling film (plastic wrap). Cling film prevents the root from drying out while you source milk or saline. A dry tooth loses all cell viability within 15 minutes. Cling film extends this window to approximately 1 hour. Avoid paper towels, tissues, and cotton wool. These materials draw moisture out of the root surface through capillary action.
Storage for Children
Children under 12 years should not store a tooth inside their cheek. Young children risk swallowing or aspirating the tooth. Place the tooth in a small container of milk or saliva collected in a clean cup. Learn more about protecting young smiles on our children’s dental care page.
When Is It Too Late to Save a Knocked-Out Tooth?
A knocked-out tooth becomes increasingly difficult to save after 2 hours outside the socket. Reimplantation success depends on two factors: total time outside the mouth and dry time (time the root was exposed to air without any storage medium).
Survival Rates by Time
| Time Outside Socket | Reimplantation Success Rate | Recommended Action |
|---|---|---|
| Under 30 minutes | 90% | Reimplant immediately |
| 30 to 60 minutes | 75% | Reimplant with splinting |
| 1 to 2 hours | 50% | Reimplant with root canal |
| Over 2 hours | Under 20% | Reimplantation unlikely |
Dry Time: The Critical Factor
Dry time matters more than total time outside the mouth. The root dries out in 15 minutes when left exposed to air. Cells undergo irreversible necrosis after 60 minutes of dry exposure. A tooth stored in milk for 3 hours has a better prognosis than a tooth left dry for 30 minutes.
Other Factors That Reduce Success
Several conditions beyond time affect whether reimplantation succeeds:
- Primary (baby) teeth are never reimplanted. Reimplanting a primary tooth risks damaging the developing permanent tooth underneath. The Australian Dental Association and the International Association of Dental Traumatology advise against reimplantation of deciduous teeth in all cases.
- Extensive pre-existing decay weakens the tooth structure, making it unable to withstand the forces of reimplantation and splinting.
- Root fracture (a crack in the root itself) prevents stable reattachment. Fractured roots require extraction.
- Severe jawbone injury at the socket site may not provide adequate bone for the periodontal ligament to reattach.
- Patient age over 40 correlates with lower success rates due to reduced cell regenerative capacity.
Even if 2 hours have passed, call Taree Dental Care on (02) 6550 0960. The tooth may still be reimplantable. If reimplantation is not possible, the dentist will discuss replacement options immediately. Delaying the call further reduces every available option.
What Happens During Reimplantation at Taree Dental Care?
Reimplantation involves cleaning the socket, reinserting the tooth, bonding a splint, and scheduling root canal therapy 7 to 10 days later. Dr Daniel Lim (BDS, University of Adelaide), who holds a special interest in oral surgery, performs these procedures at Taree Dental Care.
Step-by-Step Reimplantation Process
Step 1: Socket cleaning and assessment. The dentist examines the socket for bone fragments, blood clots, and debris. The socket is gently irrigated with sterile saline. Damaged tissue is removed. X-rays confirm the socket walls are intact and no root fragments remain.
Step 2: Tooth preparation. The avulsed tooth is rinsed with saline for 10 seconds. Dead tissue on the root surface is carefully removed with a damp gauze pad. The root surface is never scraped or curetted. The tooth is assessed for cracks, fractures, and existing restorations.
Step 3: Reinsertion. The dentist gently slides the tooth back into the socket at the correct angle and orientation. The tooth seats fully into its original position. The patient bites down on a gauze pad to confirm correct positioning.
Step 4: Splinting. A flexible splint (composite resin bonded to wire or fibre) is attached to the reimplanted tooth and the 1 to 2 neighbouring teeth on each side. The splint holds the tooth stable while the periodontal ligament heals. Splints remain in place for 2 to 4 weeks depending on the severity of the injury.
Step 5: Root canal therapy (7 to 10 days later). The dental pulp (nerve and blood supply) inside an avulsed tooth always dies after avulsion. The blood supply is severed when the tooth leaves the socket. Without treatment, the dead pulp becomes infected and causes an abscess. Root canal therapy removes the dead pulp, disinfects the root canals, and seals them to prevent infection.
Step 6: Follow-up reviews. The dentist takes X-rays at 4 weeks and 8 weeks to confirm the tooth is reattaching to the jawbone. The splint is removed at the 4-week appointment if healing is progressing well. Long-term follow-up continues at 6 months, 12 months, and annually thereafter.
What to Expect After Reimplantation
The reimplanted tooth may feel slightly different in the bite for the first few weeks. Mild discomfort and slight mobility are normal during healing. The tooth colour may darken over time as the nerve has died. A crown may be recommended 6 to 12 months after reimplantation to restore the tooth’s appearance and structural integrity. Taree Dental Care offers same-day CEREC crowns for efficient restoration.
What Are Your Options If the Tooth Cannot Be Saved?
Three replacement options exist when a knocked-out tooth cannot be reimplanted: dental implants, dental bridges, and removable partial dentures. Each option has different costs, durability, and maintenance requirements.
Option 1: Dental Implant (Gold Standard)
A dental implant is a titanium screw placed in the jawbone that supports a natural-looking crown. Implants are the gold standard for tooth replacement because they prevent bone loss, function like a natural tooth, and last 25 years or more with proper care. The implant integrates with the jawbone through a process called osseointegration, which takes 3 to 6 months. Dr Daniel Lim has a special interest in implantology and places implants at Taree Dental Care. Learn more about dental implants and the types of dental implants available.
Option 2: Dental Bridge
A dental bridge uses the 2 teeth adjacent to the gap as supports (abutments) for a false tooth (pontic) suspended between them. Bridges are fixed in place and do not require removal for cleaning. Preparing the adjacent teeth for a bridge involves removing healthy tooth structure. Bridges typically last 10 to 15 years. See our dental crowns and bridges page for details.
Option 3: Removable Partial Denture
A removable partial denture is a plastic and metal appliance with one or more false teeth attached. Dentures are the most affordable option and serve as a temporary solution while awaiting implant treatment. They require daily removal for cleaning and may feel bulky or uncomfortable. Dentures do not prevent jawbone loss because they rest on the gum surface without stimulating the bone.
Comparison of Replacement Options
| Feature | Dental Implant | Dental Bridge | Partial Denture |
|---|---|---|---|
| Lifespan | 25+ years | 10 to 15 years | 5 to 8 years |
| Bone preservation | Yes | No | No |
| Adjacent teeth affected | No | Yes (reduced) | No |
| Removable | No | No | Yes |
| Cost range | $3,500 to $5,000 | $2,500 to $4,000 | $800 to $1,500 |
How Much Does Knocked-Out Tooth Treatment Cost?
Knocked-out tooth treatment costs range from $300 for reimplantation and splinting to $5,000 for dental implant replacement. The final cost depends on whether the tooth can be saved, whether root canal therapy is required, and what restoration is needed.
Cost Breakdown
| Procedure | Cost Range | Purpose |
|---|---|---|
| Reimplantation and splinting | $300 to $600 | Save the natural tooth |
| Root canal therapy | $900 to $1,500 | Remove dead pulp after avulsion |
| Dental crown (post-reimplantation) | $1,500 to $2,000 | Restore tooth structure |
| Dental implant (single tooth) | $3,500 to $5,000 | Replace unsalvageable tooth |
| Dental bridge (3-unit) | $2,500 to $4,000 | Replace unsalvageable tooth |
| Removable partial denture | $800 to $1,500 | Temporary replacement |
Health Fund Coverage and Payment Options
Taree Dental Care offers several payment and claim options:
- HICAPS on-the-spot claims allow immediate health fund processing. Accepted funds include Bupa, HCF, Medibank, and nib. Patients pay only the gap amount on the day of treatment.
- Child Dental Benefits Schedule (CDBS) provides $1,095 over 2 years for eligible children aged 2 to 17 years. Reimplantation, examination, and X-ray costs may be covered under this scheme for qualifying families.
- Payment plans are available to spread the cost of treatment over time. Speak to our reception team about current options.
Reimplantation is significantly cheaper than implant replacement. A saved natural tooth costs $1,200 to $2,100 (reimplantation plus root canal therapy). A dental implant costs $3,500 to $5,000. Acting quickly saves both the tooth and up to $3,800 in treatment costs.
How Can You Prevent Knocked-Out Teeth?
Wearing a custom-fitted sports mouthguard during contact sport reduces the risk of dental injury by 60%. The Australian Dental Association recommends custom-fitted mouthguards over boil-and-bite chemist alternatives for all contact sports including rugby, AFL, soccer, hockey, basketball, and martial arts.
Preventive Measures
- Wear a custom-fitted mouthguard during all contact sport and training sessions. A custom mouthguard from Taree Dental Care is moulded to your exact tooth alignment, providing superior protection. Book a custom sports mouthguard fitting appointment.
- Wear a seatbelt in all vehicles. Motor vehicle accidents account for a significant percentage of dental avulsions. Seatbelts prevent face-first impacts against dashboards and steering wheels.
- Address trip hazards at home. Loose rugs, uneven flooring, and cluttered walkways cause falls that result in dental trauma, particularly in young children and elderly adults.
- Do not use teeth as tools. Opening bottles, tearing packaging, and cracking nuts with teeth causes fractures, avulsions, and chipping.
- Childproof sharp-edged furniture. Apply corner guards to coffee tables, fireplaces, and entertainment units. Toddlers fall frequently and face-height furniture edges cause dental injuries.
- Wear a helmet when cycling, skateboarding, or riding a scooter. Helmets reduce the severity of facial impact during accidents.
A custom mouthguard from Taree Dental Care costs $150 to $300. Treating a single knocked-out tooth costs $300 to $5,000. The mouthguard pays for itself by preventing one dental injury. Children aged 8 to 12 years have the highest rate of dental avulsion from sport and playground accidents. Regular comprehensive dental check-ups for children include mouthguard assessments and preventive advice.

Frequently Asked Questions
Can a knocked-out tooth be put back in?
Yes, a knocked-out adult tooth can be reinserted into its socket. Reimplantation succeeds in 90% of cases when performed within 30 minutes of avulsion. Pick up the tooth by the crown, rinse it in milk for 5 seconds, and try to reinsert it gently into the socket. Call Taree Dental Care on (02) 6550 0960 for immediate treatment. Learn more about our emergency dental care services.
How long do you have to save a knocked-out tooth?
You have 30 minutes for the highest success rate, though teeth can survive up to 2 hours with proper storage in milk. The 30-minute window preserves the highest number of viable periodontal ligament cells on the root surface. After 2 hours, reimplantation success drops below 20%. Store the tooth in cold, full-fat milk during transport to extend the survival window. See our tooth extractions page for related procedures.
What is the best liquid to store a knocked-out tooth in?
Cold, full-fat milk is the best practical storage liquid for a knocked-out tooth. Milk maintains root cell viability for up to 6 hours because its pH and osmolarity closely match human body fluid. Hanks Balanced Salt Solution (HBSS) is marginally better but rarely available outside dental practices. Never use water. Water causes osmotic shock and kills root cells within 10 minutes. Visit our contact us page for directions to the practice.
Can children have teeth reimplanted?
No, primary (baby) teeth are never reimplanted. Reimplanting a primary tooth risks damaging the permanent tooth developing underneath the gum. The International Association of Dental Traumatology advises against reimplantation of deciduous teeth in all cases. Permanent teeth in children over 12 years can and should be reimplanted following the same steps as adult teeth. Our children’s dental care team provides expert assessment of dental injuries in children of all ages.
Will a reimplanted tooth last forever?
A reimplanted tooth does not last forever but can function for 10 to 20 years with proper care. The dental pulp dies after avulsion, requiring root canal therapy within 7 to 10 days. The tooth may develop root resorption (where the body gradually breaks down the root) over months or years. Regular follow-up X-rays monitor for resorption. A crown is often placed 6 to 12 months after reimplantation to protect the tooth structure. See our information on root canal therapy and dental crowns and bridges for post-reimplantation care.
What happens if you swallow a knocked-out tooth?
A swallowed tooth passes through the digestive system without causing harm in most cases. The tooth cannot be recovered or reimplanted after swallowing. Seek medical attention at the nearest hospital emergency department if you experience difficulty breathing, persistent coughing, or chest pain. These symptoms indicate the tooth may have entered the airway (aspiration) rather than the digestive tract. An X-ray confirms the tooth’s location. Call Taree Dental Care on (02) 6550 0960 to discuss replacement options including tooth-coloured fillings and dental implants.
