Knocked-out tooth

Under 30 minutes — call us now

A knocked-out adult tooth is one of the few situations in dentistry that's truly time-critical. The faster you act, the better the odds of saving it.

First — call 540-315-3725


Don't wait. Don't book online. Call 540-315-3725 and tell us a tooth is out. During office hours we'll be ready when you arrive. After hours, leave a message — and head to the closest emergency room (Lynchburg General or Centra) if there's significant bleeding or any concern about other injuries. For the tooth itself, the actions you take in the first five minutes matter more than almost anything we'll do later.

What to do in the first five minutes


  1. 1. Find the tooth. Look for it carefully. If it landed in dirt or grass, recover the whole tooth including the root.
  2. 2. Pick it up by the crown, never the root. The crown is the part you chew with. The root has cells on its surface that need to stay alive for reimplantation — don't touch them and don't scrub them.
  3. 3. Rinse gently if dirty. Use cold milk or saline if available. Tap water is a last resort — it kills the root cells faster than other liquids.
  4. 4. Try to reinsert. If you're comfortable, position the tooth the right way around (look at the curve and compare to neighbors) and push it firmly back into the socket. Bite down gently on gauze to hold it. This is the single best transport option.
  5. 5. If reinserting isn't possible — store it in milk. A cup of cold milk preserves the root cells for several hours. Saline is the next best option. Saliva (in your cheek pouch, adults only) is third best. Water is the worst.
  6. 6. Head straight to the office. Call us on the way so we're prepared.

The 30-minute window


Research is consistent on this: a tooth reimplanted within 30 minutes has the best chance of long-term survival. After an hour, the periodontal ligament cells on the root surface begin to die — and once they die, the tooth is rejected by the body even if it physically goes back in. Storing the tooth in milk extends that window somewhat (a few hours), but faster is always better.

What we'll do when you arrive


  1. 1. Inspect the socket and the tooth. Make sure no fragments are missing and the socket is clean.
  2. 2. Numb the area. Local anesthetic before any positioning.
  3. 3. Reposition the tooth. If it's already in, we'll confirm it's in the correct position. If not, we'll seat it gently into the socket.
  4. 4. Splint to neighboring teeth. A thin wire and bonding material hold the tooth in place for one to two weeks while it re-attaches.
  5. 5. X-ray to confirm position. Verify the root is fully seated and check for any other damage.
  6. 6. Antibiotics, pain management, instructions. A short course of antibiotics, ibuprofen for the first few days, soft foods for a week, no chewing on that side until the splint comes off.
  7. 7. Follow-up in two to three weeks. Splint removal, evaluation of the nerve. Most reimplanted teeth eventually need a root canal because the nerve dies — we schedule that when the time is right.

A note on baby teeth


For a child who's knocked out a baby tooth — do not try to reinsert it. The permanent tooth developing in the gum underneath can be damaged by forcing the baby tooth back into the socket. Save the tooth in milk and bring it in. We'll X-ray the area to make sure the permanent tooth is intact, clean the socket, and talk through what to expect as the permanent tooth eventually comes in.

Long-term outlook


A reimplanted tooth that survives the first month can last decades — often the rest of your life. Some are eventually lost to root resorption (the body slowly absorbing the root) years later; if that happens, a dental implant is the standard replacement. Either way, getting the tooth back in fast gives you the best shot at keeping your own — and even if it doesn't last forever, you've bought yourself years before any other replacement is needed.

Common questions

Frequently asked


How long do I have to save the tooth?
The first 30 minutes are critical. After an hour, the chance of successful reimplantation drops sharply. Call us immediately at 540-315-3725 and head to the office — don't wait for an appointment confirmation. We'll meet you when you arrive.
Can I put the tooth back in the socket myself?
Yes, if you're comfortable doing it. Hold the tooth by the crown (the part you chew with), not by the root. Rinse it gently with milk or saline if it's dirty — don't scrub it. Position it the right way around and push it firmly back into the socket. Bite gently on gauze to hold it in place while you head to the office.
What if I can't put it back in?
Transport it in milk. Cold milk is best — whole or 2%, doesn't matter. Milk's pH and the proteins it contains keep the root cells alive longer than water or saliva. If milk isn't available, hold the tooth between your cheek and gum (adults only — choking risk in kids), or use saline solution. Avoid tap water, which kills the root cells quickly.
What if the tooth is a baby tooth?
Don't try to reimplant a baby tooth. Reimplanting a baby tooth can damage the permanent tooth developing underneath. Save the baby tooth and bring it in — we'll evaluate the area and make sure the permanent tooth underneath is intact.
Will the reimplanted tooth survive long-term?
Many do, especially when reimplanted within 30 minutes and stabilized properly. Even reimplanted teeth may need a root canal a few weeks later (the nerve often dies even after successful reimplantation), and some get reabsorbed by the body over years. Long-term, an implant is often the most durable replacement — but starting with reimplantation gives you the best chance of keeping your natural tooth as long as possible.
What happens at the appointment?
We clean and inspect the socket, reposition the tooth (or confirm yours is in correctly), and splint it to the neighboring teeth with a thin wire and bonding material. The splint stays in for one to two weeks while the tooth re-attaches. We schedule a root canal in two to three weeks if the nerve hasn't survived.
What if the tooth can't be saved?
We'll talk through replacement options the same visit if you want — typically a temporary flipper to fill the space cosmetically while you heal, followed by a dental implant or a bridge once the area is fully healed (3 to 6 months).
What about pain and infection?
Ibuprofen for the first few days. Soft foods for a week. Avoid chewing on that side until the splint comes off. Antibiotics are usually prescribed to prevent infection. Salt-water rinses keep the area clean while it heals.
