— What this is
Knocked-out tooth (avulsion): what you need to know
A completely knocked-out adult permanent tooth is one of the few true dental emergencies where every minute genuinely counts. The cells on the root surface that allow re-attachment to the jaw bone start dying within minutes of the tooth leaving the socket — by 60 minutes, success rates of re-implantation are dropping fast; by two hours, long-term success is rare. The window for action is short and the action itself is specific.
The single most important thing you can do is preserve the tooth correctly. Pick it up by the crown (the white part) — never the root. If it is dirty, rinse it briefly in milk or saliva. Do not use water — water is hypotonic relative to the cells on the root surface and damages them. Then either re-insert the tooth into the socket immediately (push gently — it should slot back in) or store it in cold milk or inside the patient's cheek pouch (saliva works as a transport medium). And get to a dentist within the hour.
Matched Harlow dentists prioritise avulsion calls absolutely — even where the schedule is full, an avulsion case is fitted in. The emergency visit involves cleaning, re-implantation, splinting to adjacent teeth for 1–2 weeks, and follow-up monitoring. Some re-implanted teeth survive for decades; some are lost despite perfect technique. The dentist will be honest about prognosis.
— Why specialist matching matters
What good emergency care looks like for knocked-out tooth (avulsion)
Absolute priority handling
Avulsion enquiries jump every queue. Matched dentists are explicitly briefed to fit avulsion cases the same hour — even displacing routine patients if needed.
Correct re-implantation technique
Re-implantation is straightforward in concept but easy to do badly. Splinting tension, occlusal adjustment, and the post-implantation antibiotic and tetanus protocol all matter. Experienced dentists get this right.
Honest prognosis
Not every re-implanted tooth survives. The matched dentist will give you a realistic prognosis based on time-out-of-socket, root maturity, and damage to the socket — not false reassurance.
Clear plan B if re-implantation fails
Even where re-implantation is impossible or unsuccessful, the dentist immediately discusses the replacement options (implant, bridge, or denture) with timing and costs. You leave with a path forward, not just a missing tooth.
— Common mistakes
Three things to avoid in the first hour after a knocked-out tooth
1. Rinsing the tooth in water
Water is hypotonic relative to the cells on the root surface — it draws water into the cells and damages them. This destroys the very thing that makes re-attachment possible. Rinse briefly in milk or saliva instead.
2. Holding the tooth by the root
Pick the tooth up by the white crown only. The root cells are extremely fragile and any contact damages them. If you have already touched the root, all is not lost — preserve correctly from now on and get to a dentist immediately.
3. Trying to re-implant a baby tooth
Adult permanent teeth re-implant; baby teeth do not. Re-inserting a baby tooth risks damaging the developing adult tooth bud underneath. Bring the tooth so the dentist can check it is whole, but leave the socket alone.
— Often connected to
Broken or chipped tooth
Avulsion injuries rarely happen in isolation — adjacent teeth are often fractured or loosened by the same impact. The dentist examines all teeth in the trauma zone, not just the one obviously missing.

Is matching for knocked-out tooth (avulsion) right for you?
Avulsion (knocked-out tooth) matching is the right route if:
- A permanent adult tooth has been completely knocked out within the last few hours
- The tooth itself is intact (not shattered into multiple pieces)
- The patient is alert and the avulsion is the primary concern (not part of major head trauma — call 999 for that)
- You are able to reach a Harlow dental practice within 1–2 hours of the injury
- You have preserved the tooth in milk, saliva, or re-inserted it in the socket
— The matching process
How knocked-out tooth (avulsion) matching works
Preserve the tooth correctly NOW
Pick it up by the crown only. Rinse briefly in milk if dirty (NOT water). Re-insert into socket immediately if you can; otherwise store in milk or inside the cheek. Time matters — every minute counts.
Submit the matching form marked "knocked-out tooth"
We treat avulsion as critical priority. The form takes under one minute — you can fill it in while heading to the practice.
We connect you immediately
Avulsion calls bypass routine queueing. We aim to confirm a Harlow practice within 15 minutes during opening hours.
Re-implantation, splinting, and follow-up
The dentist re-implants, splints the tooth to its neighbours, and books follow-up appointments to monitor healing. Antibiotics and a tetanus check complete the protocol.
This is a dental matching service, not a medical service
For genuine medical emergencies — uncontrolled bleeding, facial swelling spreading to your eye, throat or neck, difficulty breathing or swallowing, or feeling severely unwell — these are hospital problems and need IV antibiotics, not a dental appointment.
