A Chipped, Cracked or Knocked-Out Front Tooth in an Adult: What to Do in the First Hour

Practice clinician: Gerald M. Marlin, DMD, MSD, prosthodontist, Elite Prosthetic Dentistry, Friendship Heights, Washington, DC. Last updated October 30, 2026.

An adult front tooth injury is frightening out of proportion to its danger, because it is visible and because a missing front tooth feels like a missing face. Most of these injuries are repairable, and the one that is truly time-sensitive, a tooth knocked out whole, can often be saved if the first hour is handled correctly. This page sets out what to do for each kind of injury, when the emergency room comes first, what can be done the same day, and how the final result is planned.

In the Next Hour

If the tooth was knocked out whole:

1. Find it and pick it up by the crown, the white part. Do not touch the root.
2. If it is dirty, rinse it briefly in milk or saline. Do not scrub it, do not dry it, do not wrap it in tissue.
3. If you can, place it back in the socket the right way round and hold it with gentle pressure by biting on a clean cloth. If you cannot, keep it in a cup of milk or hold it in your mouth between cheek and gum. Not in water.
4. Call the office immediately and say the tooth is out. If the practice cannot see you within the hour, go to whichever dental office can. Time out of the mouth is what decides whether the tooth survives.

If the tooth chipped:

1. Find the fragment if you can and keep it in a little milk or saliva. It can sometimes be bonded back.
2. Rinse your mouth gently. Cover a sharp edge with orthodontic wax or sugar-free gum.
3. Avoid biting with that tooth. Keep cold away if it is sensitive.
4. Call the office. A chip that exposes the yellow inner layer, or that is sensitive, should be seen the same day if possible.

If the tooth is cracked but intact:

1. Do not chew on it at all. A crack extends with load.
2. Note whether it hurts on biting or on release, and whether it is sensitive to cold; the clinician will ask.
3. Call the office for an evaluation.

If the tooth was pushed out of position but is still in the socket: do not try to move it back yourself. Bite gently on a cloth to stabilize it and call immediately.

For all of these: over-the-counter pain relief as directed on the label and as approved by your physician, and a cold compress on the lip for swelling.

When to Go to the Emergency Room Instead

Go to the emergency room, or call 911, before anything else for: loss of consciousness, confusion, vomiting or severe headache after the injury; a suspected jaw fracture (the teeth no longer meet as they did, or the jaw will not open or close normally); a deep cut to the lip, tongue or face that will not stop bleeding; difficulty breathing or swallowing; or any injury where a tooth or fragment may have been inhaled. Take the knocked-out tooth with you in milk; tell the staff it needs attention. Call the dental office afterward.

What Can Wait Until Office Hours

A small chip with no pain or sensitivity can wait until the next office day with the edge covered. A cracked tooth that is not painful can usually wait until the next office day as long as it is not chewed on. A knocked-out tooth cannot wait, and a tooth pushed out of position should be seen the same day.

What the Visit Involves

The tooth, its neighbors, the lip and the bite are examined and X-rayed. The findings decide the same-day treatment:

• A chip. The fragment is bonded back where possible, or the tooth is rebuilt with tooth-colored bonding matched to the neighbors, often in the same visit. A larger loss is planned for a veneer or crown, with a bonded provisional meanwhile.
• A crack. The extent is assessed. A crack confined to the crown of the tooth is protected with a crown; a crack that reaches the root may make the tooth unsavable, and the alternatives are discussed. Our guide on saving the tooth or replacing it with an implant explains that decision.
• A knocked-out tooth. If it can be replanted, it is repositioned, splinted to the neighbors for a period, and monitored; root canal treatment is usually needed afterward. If it cannot, the socket is managed and a provisional tooth is fitted so there is no gap, and the replacement is planned.
• A displaced tooth. It is repositioned and splinted, and monitored for nerve health.

A front tooth that cannot be repaired that day leaves with a provisional, made in the practice’s on-site laboratory, so the patient is never without a tooth in the front of the mouth.

Why It Happened

Falls, sports, cycling, a hard object in food, and an elbow in a crowd account for most adult front-tooth injuries. Some chips and cracks have a second cause: a bite that has been loading the front teeth too heavily, often because the back teeth have worn down or been lost, so the front teeth have been doing work they were not built for. When a front tooth chips on something ordinary, the bite is checked, because a repaired tooth in the same bite will chip again. Our guide on why crowns keep breaking describes the forces.

What an Emergency Often Reveals

A front tooth that breaks without much provocation is often a sign of wear elsewhere: edges thinned by grinding, back teeth that have lost height, a bite that has shifted forward. The emergency visit repairs the tooth; the follow-up examines why it broke and whether the other front teeth are at the same risk. Patients whose front teeth matter to their work will find more in our guide on front teeth for people who speak for a living.

How Elite Prosthetic Dentistry Handles a Front Tooth Injury

Call the office; a knocked-out tooth is treated as urgent, and all injuries are triaged by urgency with same-day visits arranged when the schedule allows. The same-day visit stabilizes, repairs or provisionalizes the tooth. Dr. Gerald M. Marlin plans the final restoration with the neighbors, the lip line and the bite in view, and where a tooth cannot be saved, the practice plans and carries out the implant or bridge that replaces it. The on-site laboratory, operating since 1985, makes the provisional and the final restoration without an outside laboratory in the chain, which matters when the tooth in question is the one everyone sees.

When Another Setting Fits Better

The emergency room comes first for the signs listed above. A knocked-out tooth should go to whichever dental office can see the patient within the hour, which may not be this one. Children’s tooth injuries are managed differently and belong with a pediatric dentist or a general dentist who treats children. A tooth needing root canal treatment may be referred to an endodontist for that step and restored in the practice afterward.
