What To Do If Your Child's Tooth Is Knocked Out

February 12, 2025

Accidents happen, especially with kids who love to run, jump, and play. 


A knocked-out tooth can be a scary experience for parents and children, but knowing how to react quickly and correctly can make all the difference. 


Whether it's a baby tooth or a permanent tooth, properly handling the situation can help minimize pain, reduce complications, and even save the tooth. 


Here's what every parent should know in case their child's tooth gets knocked out.


Stay Calm and Assess the Situation

Your first instinct might be to panic, but staying calm is crucial. A knocked-out tooth often results in bleeding, tears, and a scared child. 


Take a deep breath and reassure your child that everything will be okay. Once your child is calmer, assess the severity of the injury.


Check for other facial injuries, such as cuts, swelling, or a concussion. If your child is unconscious, dizzy, or vomiting, seek emergency medical help immediately.


If the injury is limited to the mouth, focus on handling the lost tooth appropriately.


Determine if It's a Baby or a Permanent Tooth

The next step is determining whether the knocked-out tooth is a baby (primary) or a permanent (adult) tooth.


  • Baby Tooth: If your child loses a primary tooth due to an accident, do not try to reinsert it. Baby teeth naturally fall out to make room for permanent teeth, and reinserting them could cause damage to the developing adult tooth underneath. However, you should still contact a dentist to ensure no further treatment is needed.
  • Permanent Tooth: If the tooth is an adult tooth, time is critical. The faster you act, the higher the chances of saving the tooth. You should reinsert it within 30 minutes to increase the likelihood of successful reattachment.


Handling A Permanent Tooth Knockout

Properly Handle the Tooth

Proper handling and quick action are essential if your child loses a permanent tooth. Again, remain calm and assess the entire situation.


  1. Pick up the tooth by the crown. Avoid touching the root (if possible), as this can damage the delicate tissue needed for reattachment.
  2. If dirty, gently rinse with water. Do not scrub, use soap, or remove any attached tissue fragments. Rinse it under lukewarm water for no more than 10 seconds.
  3. If possible, try to reinsert the tooth. If your child cooperates, gently place the tooth back into the socket and have them bite down on a clean cloth to keep it in place.
  4. If reinsertion isn't possible, keep the tooth moist. If you can't put the tooth back in for whatever reason, place it in a container with milk, saline solution, or your child's saliva. Avoid storing it in water, as this can damage the cells needed for reattachment.
  5. Transport the tooth carefully. If you are going to the dentist, keep the tooth in a sealed container with milk or a specialized tooth preservation solution. Proper transport increases the chances of successful re-implantation.

Control Bleeding and Pain

To help slow the bleeding, have your child gently bite down on a piece of gauze, a clean cloth, or a tea bag. Applying a cold compress to the outside of the mouth can help reduce swelling and numb the pain.


If your child is experiencing significant discomfort, you may give them an age-appropriate pain reliever like acetaminophen or ibuprofen. However, avoid giving aspirin to children, as it may increase bleeding.


Additionally, make sure your child avoids drinking through a straw, eating hard foods, or poking at the injured area with their tongue, as these actions could cause further irritation or disrupt clot formation.


Seek Emergency Dental Care

Time is of the essence when dealing with a knocked-out permanent tooth.


Contact a dentist immediately and let them know about the situation. If it's after hours, look for an emergency dental clinic. A dentist will assess whether the tooth can be successfully reattached or if additional treatment is needed.


If the dentist cannot save the tooth, they will discuss replacement options, such as a dental implant, bridge, or partial denture, to maintain proper oral function and appearance.


The earlier you seek professional care, the better the outcome.


Follow-Up Care and Prevention

After emergency treatment, follow the dentist's instructions carefully.


Your child may need to eat soft foods and avoid biting directly on the injured tooth while it heals. Regular checkups with their primary dentist will help monitor healing and detect complications.


To prevent future dental injuries, several precautions can be taken.


  • Encourage your child to wear a mouthguard during sports.
  • Childproof your home by cushioning sharp furniture edges.
  • Teach kids safe play habits and the importance of protecting their teeth.
  • Avoid giving young children hard candies, popcorn kernels, or ice cubes to chew on, as these can lead to chipped or broken teeth.


When to Follow Up with the Dentist

Even if the initial treatment goes well, follow-up visits are essential to ensure the reinserted tooth is healing correctly. Your dentist may recommend possible tests or additional procedures.


  • Regular x-rays to monitor the health of the re-implanted tooth.
  • A root canal (if there has been damage to the tooth's nerve).
  • A dental splint to stabilize the tooth in place for several weeks.


It's also a good idea to monitor your child's oral health for changes in color, swelling, or sensitivity in the affected area, as these may indicate complications that require further attention.

When it comes to dental care, your primary goal is always to preserve your natural teeth. However, there are instances where extraction becomes the best course of action to prevent further complications and alleviate pain. We recommend emergency tooth extractions when a tooth is severely damaged or infected and cannot be saved through other treatments such as root canals or crowns. Let's explore the common reasons for emergency extractions and what to expect during and after the process. Common Reasons for Emergency Extractions Severe Tooth Decay One of the most common reasons for emergency tooth extractions is severe tooth decay. When decay progresses extensively, it can compromise the tooth's structural integrity. Suppose the decay reaches the pulp or nerve of the tooth. In that case, it can cause excruciating pain and significantly increase the risk of infection. In such cases, an emergency extraction may be necessary to prevent the spread of infection and restore your oral health. Removing the decayed tooth can eliminate the source of pain and prevent further damage to surrounding teeth and tissues. Dental Trauma Accidents or injuries can result in severe dental trauma, such as a fractured or dislodged tooth. Extraction may be the best option when a tooth is beyond repair or poses a risk to your oral health. A strong dental care team should have extensive experience handling dental emergencies and providing immediate care for dental trauma. They will be equipped to assess the extent of the damage and determine whether an extraction is necessary to protect your oral health and alleviate pain.  Problem-Focused Examination Before proceeding with an extraction, our dentists will perform a problem-focused examination of your dental condition, usually including X-rays, to assess the extent of the problem and determine the necessity of extraction. This thorough evaluation helps your dental team make informed decisions about your treatment and ensures the best possible outcome for your oral health.

Maintaining good oral health is crucial for overall well-being. Yet, many people overlook the significant role that lifestyle choices play in the health of their teeth and gums. From smoking and excessive alcohol consumption to sugary drinks and poor dietary habits, various factors can have a profound impact on oral health. Let's explore how these lifestyle choices affect your oral health and what you can do to maintain a healthy smile. Smoking and Oral Health Smoking is not only detrimental to your lungs but also wreaks havoc on your oral health. The chemicals in tobacco smoke can irritate gum tissue, leading to inflammation and increasing the risk of gum disease. Moreover, smoking restricts blood flow to the gums, impairing their ability to fight off infection and heal properly. Over time, smokers are more likely to experience tooth loss and other serious oral health issues. Quitting smoking is essential for preserving the health of your teeth and gums, and seeking support from healthcare professionals can significantly improve your chances of success. Alcohol Consumption and Oral Health Excessive alcohol consumption is another lifestyle factor that can harm your oral health. Alcohol dries out the mouth, reducing saliva production and creating an environment conducive to bacterial growth; this increases the risk of cavities, gum disease, and even oral cancer. While moderate alcohol consumption may not pose significant risks, it's essential to be mindful of your intake and practice moderation. Drinking plenty of water can help keep your mouth hydrated and flush out harmful bacteria, promoting better oral health. Soda and Carbonated Drinks Sugary drinks like soda and carbonated beverages are a significant culprit behind tooth decay and erosion. These drinks contain excessive sugar, which bacteria in the mouth feed on, producing acids that attack tooth enamel. Additionally, the carbonation in these beverages increases their acidity, further eroding enamel and weakening teeth. Limiting your consumption of sugary drinks and opting for water or unsweetened beverages can significantly reduce your risk of dental problems.
