Knocked-out tooth emergency: taking these steps improves the chances that your Princeton dentist can successfully replant and preserve your natural tooth.
Having a tooth knocked-out because of a contact sport, sudden fall, an assault, or vehicle accident is one of the most time-sensitive dental emergencies you can experience.
Your actions in the first 30 to 60 minutes before reaching an emergency dentist heavily dictates whether your knocked-out tooth—medically known as an avulsed tooth—can be saved or lost permanently.
In this blog post, Dr. Nesrine Bestandji, a family and emergency dentist in Princeton, New Jersey, shares a first aid sequence to follow immediately after your tooth has been knocked-out. Taking these swift steps increases the chances that your Princeton dentist can successfully replant and preserve your natural tooth.
Note: These instructions apply only if the injured individual is breathing normally and fully conscious. If not, bypass dental first aid and promptly call 911.
Knocked-Out Tooth Care: 4 Immediate First Aid Steps to Take
- Find and Handle the Tooth with Extreme Care
Every tooth has two main parts: the crown (the visible white surface used for biting and chewing food) and the root (the unseen structure hidden below the gumline).
The root has living connective tissues that secure your tooth to the jaw, called the periodontal ligament (PDL) cells.
If your tooth lands on the ground, pick it up right away strictly by the crown. Never touch the root under any circumstances, as handling the lower section could irreversibly damage the hyper-sensitive PDL cells that are critical for saving your tooth.
Once those tissues are destroyed, natural reattachment of your knocked-out tooth becomes nearly impossible—and even a tooth that initially seems to have been successfully re-implanted will likely fail over time.
- Gently Rinse (Only If Dirty)
If you see debris, hold the tooth under cold running water for a maximum of 10 seconds.
Don’t use soap or disinfectants, avoid scrubbing, and skip pat drying to keep fragile root fibres intact, so your tooth has the best chance at reattaching.
- Reinsert the Tooth Into Its Socket
NOTE: skip this instruction if you’re a parent whose child’s baby tooth has been knocked out. Dentists advise against pushing a milk tooth back because it can scar or crush the growing permanent adult tooth underneath the gum, potentially causing serious enamel defects, tooth impaction, or root malformation years later.
Front teeth—your lower and upper incisors—are the most common victims of an avulsion. Often, if you take the tooth by the crown and apply soft, steady pressure, it will slide right back into its space in the gum.
Before attempting to put the knocked-out tooth back in, check that it’s facing the correct direction.
Once seated, bite down gently on a clean napkin, handkerchief, or gauze. The constant biting pressure keeps the tooth in place and moist while you make your way to an emergency dentist.
Aim to reinsert the tooth as soon as possible. Research shows reimplanting the tooth at the scene within 5 minutes yields the highest long-term success rate, whereas 60 minutes marks the practical window for tooth survival before extra medical steps are needed.
Please don’t try to force the knocked tooth into the gum socket; this will only damage the surrounding bone and tissue. If it fails to go back effortlessly, simply move to the next first aid step.
- Maintain Tooth Moisture
Within minutes of being dislodged, your tooth’s periodontal ligament cells start to die from dryness. If you can’t safely put the tooth back, submerge it in a small milk container.
Milk contains the ideal balance of proteins, salts, and pH levels that keep the PDL cells alive until a dentist re-anchors your tooth.
When milk isn’t available, tuck the knocked-out tooth inside the mouth between the cheek and gums. Saliva will keep it wet—just ensure the injured person is mature enough not to swallow it. Sterile saline solution is another safe substitute.
Don’t use tap water, as through osmotic pressure changes it causes the root cells to swell and burst, and avoid wrapping the tooth in dry tissue or paper towels, which dehydrates the cells—both make reimplantation far more difficult.
After the tooth is safely stored, rush to the dentist. You can call the practice en route to brief the dental team with key details, including when and how the tooth came off, whether it’s an adult or baby tooth, how you’ve stored the tooth, and if there are secondary symptoms like severe bleeding, swelling, or dizziness.

What to Expect at the Princeton, NJ Emergency Dental Clinic
Your dentist will first clean the empty gum socket, guide the tooth back into its proper position (assuming you didn’t do it yourself), and secure it to adjacent teeth with a flexible splint made from composite material or thin wire.
This splint typically remains for 1 to 2 weeks for a tooth replaced promptly, or roughly 4 weeks if it stayed out of your mouth for longer than an hour. This gives the injured area sufficient time to heal while allowing subtle, healthy tooth movement.
Subsequent visits are necessary to remove the splint and assess how well the tooth is stabilizing. Additionally, if the knocked-out tooth triggers an infection within the inner nerve tissue, your dentist will likely initiate root canal therapy between 7 and 14 days following re-implantation.
When reinsertion isn’t viable—whether due to extensive root fracture, prolonged time out of the socket, or underlying gum disease—your dentist will walk you through alternative restorative treatments.
Standard replacement choices include dental implants, fixed bridges, and partial dentures. These solutions fill the tooth gap, restoring comfortable chewing, clear speech, and a complete, natural-looking smile.
