When a tooth is knocked out, time is the most critical factor. The first hour determines the chances of saving the tooth. Staying calm and acting quickly with the right steps can make all the difference. This guide provides clear, actionable instructions for handling this dental emergency.
A knocked-out tooth, clinically known as a dental avulsion, is a serious but often fixable dental emergency. The immediate goal is to protect the thousands of living cells on the tooth's root, which are essential for successful reattachment.
This guide outlines the critical first-aid steps, from locating the tooth to preserving it correctly for transport to the dentist.
Follow this clear sequence: find the tooth, handle it by the crown only, and place it in a proper storage solution immediately.
First, locate the tooth. When you find it, handle it with extreme care.
The most important rule is to only touch the crown—the whiter, chewing part of the tooth. Never touch the root, which is the yellowish part that sits below the gumline. Touching the root can crush the delicate cells needed for reimplantation.
If the tooth is dirty, rinse it gently with cold water or milk for no more than 10 seconds. Do not scrub, wipe, or use any soap. The goal is only to remove visible debris, not to sterilize it. Scrubbing will permanently damage the root surface and prevent the tooth from being saved.
Keeping the tooth viable is the next priority, and your first-aid actions directly impact its survival. The best course of action is to gently reinsert the tooth into its socket, ideally within 15 to 60 minutes. If possible, gently push it back into place and have the person bite down on a clean piece of gauze or cloth to hold it steady.
If reinsertion is not possible, do not force it. The next best action is to keep it moist.
Place the tooth in a small container of cold milk. This is the best and most accessible option at home. If milk is unavailable, placing the tooth inside the cheek (using saliva) is a viable alternative, but only if the person is old enough not to swallow it. Avoid storing it in plain tap water, as its incorrect pH balance can rapidly kill the root cells.
This is a true dental emergency, where your quick thinking is the first step toward a positive outcome. For more details, consult our guide on handling a dental emergency.
To make it even clearer, here’s a quick-reference guide for that critical first hour.
Following these guidelines dramatically increases the chances of successful reimplantation and can help you avoid more complex dental procedures.
After finding and carefully handling the tooth, the next few minutes are critical. The living cells on the tooth's root are extremely fragile, and how you store and transport the tooth directly determines if it can be saved.
A tooth that dries out is almost always a lost cause. Research shows that after 60 minutes of being dry, most of the crucial periodontal ligament cells on the root surface die. At that point, successful reimplantation becomes highly unlikely. Proper storage is the single most important factor for success.
The storage medium you choose is vital. While a specialized tooth preservation kit (like Hank's Balanced Salt Solution) is the ideal standard, it is rarely available.
Fortunately, the next best thing is likely in your refrigerator: cold cow's milk. Its chemical properties, including its pH level and protein content, are well-suited to keep root cells alive and hydrated without causing damage.
Why Not Water? Never store a knocked-out tooth in tap water or bottled water. Water is hypotonic, meaning it has a lower salt concentration than the cells on the root. This imbalance causes water to rush into the cells, making them swell and burst—a process called lysis that kills the cells needed for reattachment.
The location of the injury will dictate your available options. Knowing the best choice in the moment is key.
Regardless of the method, your primary goal is to get to an emergency dentist immediately. Here is a quick breakdown of your options.
The correct response to a knocked-out tooth depends on one crucial detail: is it a baby tooth or a permanent adult tooth? Mistaking one for the other can lead to serious, long-term dental problems.
This injury, known as dental avulsion, is a common emergency. In the United States, over five million teeth are knocked out annually, with the highest incidence in children between 7 and 11 years old.
If a child loses a baby tooth due to an accident, resist the instinct to put it back in. You should never attempt to reinsert a knocked-out baby tooth.
The primary concern is protecting the developing permanent tooth underneath. Forcing the baby tooth back into the socket can damage this fragile tooth, potentially causing discoloration, improper growth, or permanent structural damage.
Instead of reinsertion, follow these steps:
A knocked-out baby tooth is not a reimplantation emergency. The priority shifts from saving the lost tooth to protecting the permanent one that will eventually take its place. Your dentist may recommend a space maintainer to ensure other teeth don't shift into the gap.
For a permanent tooth, the approach is the opposite. Time is of the essence, and the primary goal is immediate reimplantation. Every minute the tooth is out of the mouth, the chance of saving it decreases.
If an adult tooth is knocked out, immediately try to gently place it back into its socket. Handle it only by the crown (the chewing surface), never the root. If it's dirty, give it a quick rinse with cold milk—not water—and carefully guide it back into place. Have the person bite down on a clean cloth to hold it steady.
If you cannot reinsert it, do not force it. Place the tooth in a small container of cold milk and get to an emergency dentist immediately. Swift action is the single most important factor in giving the tooth a fighting chance.

Arriving at the dental office with a knocked-out tooth is stressful. Understanding the step-by-step process can help reduce anxiety. Our priority is to work quickly and gently to give your tooth the best chance of survival.
Upon arrival, we will immediately bring you to an exam room. We will assess for other injuries to your lips, gums, or jaw and may take a digital X-ray to check for damage to the socket or surrounding bone.
While you are being examined, a dental assistant will carefully handle the tooth, gently rinsing it with a sterile saline solution to remove debris without damaging the root cells. This step is critical and requires great care.
Simultaneously, we will prepare the empty socket. The area will be numbed completely. We will then gently flush the socket with saline to clear out blood clots and debris. A clean socket is essential for successful reattachment.
This preparation sets the stage for a successful procedure.
Once the area is numb and both the tooth and socket are clean, the dentist will carefully guide the tooth back into its original position. This is a controlled and precise procedure; you should feel no more than slight pressure.
After the tooth is repositioned, it must be stabilized to heal, similar to setting a broken bone. To achieve this, we use a dental splint.
A splint is a supportive wire or composite material bonded to the reimplanted tooth and one or two healthy neighboring teeth. This temporary device acts as a brace, holding the tooth steady while the periodontal ligament fibers reattach to the jawbone.
The splint is crucial for successful healing over the next few weeks, protecting the tooth from the forces of talking and chewing. Dental injuries are common; an in-depth analysis of dental injuries found that over one billion people globally have experienced dental trauma, highlighting the importance of proper emergency care.
Finally, you will receive detailed aftercare instructions covering:
A follow-up appointment will be scheduled to monitor your progress and determine when the splint can be removed.
Reinserting the tooth is the first major step, but the following weeks are critical for healing and determine the long-term success of the procedure. Proper aftercare is as important as the initial emergency response.
Your dentist will have placed a splint—a thin wire bonded to the reimplanted tooth and its neighbors—to hold it still while the periodontal ligament fibers reattach to the jawbone. This healing process is essential for success.
The splint typically remains in place for two to four weeks, depending on the severity of the injury. During this time, your main responsibility is to protect the tooth from any unnecessary pressure.
Your daily habits directly impact the tooth's healing. Following your dentist's instructions is crucial for a successful outcome.
Focus on these key actions:
The goal is to create a calm, stable environment for the tooth to heal. Any excessive force from chewing hard foods or improper brushing can disrupt the fragile reattachment process and lead to failure.
While most reimplanted teeth heal well with proper care, complications can occur. Be vigilant and contact us immediately if you notice any warning signs.
Monitor for these potential issues:
A common long-term outcome for a reimplanted adult tooth is the need for root canal treatment. The trauma from the injury often damages the tooth's nerve and blood supply. A root canal, typically performed one to two weeks after the incident, removes this damaged tissue to prevent infection and preserve the tooth's structure.
Even with the best care, not every tooth can be saved. If reimplantation fails, modern dentistry offers excellent solutions to restore your smile. A dental implant can permanently replace a lost tooth and function just like a natural one.
Even with clear instructions, a dental emergency can be chaotic and raise many questions. Here are straightforward answers to some of the most common concerns we hear from patients.
This is a critical question. While the first 60 minutes is the "golden hour" for reimplantation success, you should not give up hope. The delicate cells on the tooth's root begin to die when exposed to air, and after an hour, the chances of long-term success decrease significantly.
However, you should always treat the tooth as if it can be saved. Place it in cold milk or another appropriate solution and get to a dentist immediately, even if more than an hour has passed. We will always do everything possible to save it. Sometimes, even if the tooth doesn't fully reintegrate for the long term, it can serve as a natural placeholder for a period.
Never assume a tooth is a lost cause. Your quick action gives us the best chance to intervene, regardless of the time elapsed. Let a dental professional make the final determination.
If the tooth cannot be found or is shattered, your focus should shift to managing the injury. Gently rinse your mouth with warm salt water and apply gentle pressure with clean gauze to control bleeding from the socket. A cold pack on the outside of your cheek will help manage pain and swelling.
If you find the tooth in pieces, collect any large fragments and bring them with you. In either situation, you still need an emergency dental visit promptly. We must check the socket for debris and ensure there is no damage to surrounding teeth or your jawbone.
It can be disheartening if a knocked-out tooth cannot be saved. However, leaving a gap can cause neighboring teeth to shift, leading to bite problems and other issues. Modern dentistry offers excellent, permanent solutions to restore your smile.
Losing a tooth does not have to permanently affect your health or confidence. We will discuss all available options to determine the best path forward for your specific situation.
