Knocked-Out Tooth: What to Do Right Now

A knocked-out (avulsed) permanent tooth is one of the few true dental emergencies where the clock genuinely matters. What you do in the first hour largely decides whether the tooth can be saved and reattached — or whether you’re looking at a gap and a future implant. This guide walks you through exactly what to do right now, how to store the tooth, what a dentist can do, and what it realistically costs in Central Florida.

A note on this guide: If a permanent tooth was just knocked out, act now — follow the first-aid steps below and get to a dentist immediately. This is informational content, not clinical advice. Costs are planning estimates, not quotes. For severe bleeding, facial trauma, or trouble breathing, treat it as a medical emergency.

First: is it a baby tooth or a permanent tooth?

This matters. A knocked-out baby (primary) tooth is generally not reimplanted — putting it back can damage the developing permanent tooth underneath. If a child loses a baby tooth to injury, control any bleeding, keep the child calm, and call a dentist to check for other damage, but don’t try to reinsert it.

A knocked-out permanent tooth is a save-it-now situation. The rest of this guide is about permanent teeth.

What to do right now — the 30–60 minute window

The single biggest factor in saving a knocked-out permanent tooth is how quickly it’s placed back in the socket. Reimplantation within about 30 minutes gives the best odds; after roughly 60 minutes, the cells on the root surface begin to die and success drops sharply. Move quickly but calmly:

Find the tooth and pick it up by the crown — the white chewing part — never the root. The root surface has delicate cells that must survive for the tooth to reattach. Touching or scrubbing them ruins the chance of success.
If it’s dirty, rinse gently for a few seconds with milk, saline, or the person’s own saliva. Do not scrub it, use soap, or wipe it dry, and do not remove any attached tissue fragments.
Try to place it back in the socket right away. Orient it the correct way (matching the neighboring teeth), push it in gently with your fingers, and have the person bite down softly on a clean piece of gauze or cloth to hold it in place.
If you can’t reinsert it, store it properly (see below) — the tooth must stay moist at all times. A dry tooth is much harder to save.
Get to a dentist immediately — ideally within 30 minutes. Call ahead so they’re ready for you.

Never let the tooth dry out, and never store it in plain tap water — water damages the root cells through osmosis.

How to store a knocked-out tooth

If reinsertion isn’t possible, the storage medium matters, in this order of preference:

A tooth-preservation kit (such as Save-A-Tooth), if you happen to have one — these contain a balanced salt solution designed for exactly this.
Cold milk — widely available and one of the best practical options. The proteins and sugars help keep the root cells alive.
Saliva — tuck the tooth inside the cheek (only for a conscious older child or adult who won’t swallow it), or spit into a cup and submerge the tooth.
Saline (contact lens saline or salt water) if nothing else is available.

Get to the dentist as fast as possible regardless of the medium — storage buys you time, it doesn’t stop the clock.

What the dentist does

At the office, the dentist will reposition and reimplant the tooth if it wasn’t already back in, then splint it to the neighboring teeth with a thin wire or bonded material to hold it steady while the ligament heals — usually for a couple of weeks. Because the nerve is often damaged by the trauma, most reimplanted permanent teeth eventually need a root canal to prevent infection and internal discoloration; this is sometimes started within the first week or two. You’ll also likely need a tetanus check if the injury was outdoors or dirty.

If the tooth was out too long, badly fractured, or dried out, reimplantation may not be viable — in which case the conversation shifts to replacing it.

If the tooth can’t be saved: replacement options

Not every knocked-out tooth survives. When it can’t be saved, the main replacement paths are:

Dental implant — the closest thing to a natural tooth, and the long-term standard. Because trauma often damages the surrounding bone, an implant here sometimes needs a bone graft first, and healing plays out over several months.
Dental bridge — a fixed option that uses the neighboring teeth for support, typically faster and less expensive up front than an implant.
Partial denture — the most economical option, often used as a temporary or when multiple teeth are involved.

What it costs in Central Florida

Costs depend entirely on whether the tooth is saved or replaced. These are planning ranges for the Central Florida market, not quotes:

Service	Central FL cost
Emergency exam	$100–$400
Reimplantation & splinting	Often bundled into the emergency/exam visit
Root canal (commonly needed after)	$700–$1,800
Crown (to protect the tooth)	$1,000–$1,800
Simple extraction (if not salvageable)	$150–$400
Surgical extraction	$300–$800
Bone graft (if replacing with an implant)	$350–$3,000
Dental implant (full replacement)	$3,000–$5,800

Saving the tooth — reimplantation, a root canal, and a crown — commonly totals in the low four figures, but keeps your natural tooth root and bone. Replacing the tooth with an implant is a larger investment spread over months. Either way, the emergency visit itself is the small part of the bill; the restoration is where the cost lives.

Preventing avulsion in the first place

Most knocked-out teeth in Central Florida come from sports, falls, bikes, and car accidents. A properly fitted mouthguard for contact sports is the single most effective prevention, and it’s inexpensive relative to a knocked-out tooth. If you or your kids play basketball, soccer, football, or do jiu-jitsu, wear one.

Frequently asked questions

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

The best window is about 30 minutes; reimplantation within an hour gives the strongest odds. After roughly 60 minutes, the root’s cells begin dying and success drops significantly. Keep the tooth moist and get to a dentist as fast as possible — speed matters more than anything else.

Should I put a knocked-out tooth back in the socket?

Yes, if it’s a permanent tooth and you can. Pick it up by the crown, rinse gently if dirty, orient it correctly, and press it back into the socket, then bite on gauze to hold it. If you can’t reinsert it, store it in milk or saliva and see a dentist immediately. Do not reinsert a baby tooth.

What’s the best way to store a knocked-out tooth?

A tooth-preservation kit is ideal; cold milk is the best widely available option; saliva or saline also work. Never use plain tap water — it damages the root cells. Whatever you use, keep the tooth submerged and moist and get to the dentist quickly.

Will a reimplanted tooth need a root canal?

Usually, yes. The trauma often damages the tooth’s nerve, so most reimplanted permanent teeth need a root canal — sometimes within the first week or two — to prevent infection and discoloration. Your dentist will monitor the tooth and advise on timing.

How much does it cost to fix a knocked-out tooth in Central Florida?

The emergency exam runs $100–$400, with reimplantation and splinting often bundled in. Saving the tooth typically adds a root canal ($700–$1,800) and crown ($1,000–$1,800). If it can’t be saved, replacement ranges from an extraction ($150–$400) plus a bridge or an implant ($3,000–$5,800, sometimes with a bone graft).

Can a knocked-out baby tooth be put back?

No. A knocked-out baby (primary) tooth is generally not reimplanted, because doing so can damage the permanent tooth developing beneath it. Control bleeding, keep the child calm, and call a dentist to check for other injuries — but don’t try to reinsert it.
