KEY TAKEAWAYS
A knocked-out permanent tooth has the highest chance of survival when it is handled correctly and professional care is obtained within 30 to 60 minutes.
You must handle a knocked-out tooth strictly by the crown (the visible chewing surface) to avoid damaging the fragile cells on the root.
Storing an avulsed tooth in cold milk or your own saliva keeps the root surface moist and viable during transport.
Patients in Downtown Denver experiencing dental trauma should contact Dr. Thurman immediately for priority emergency triage.
Knocked-out primary (baby) teeth are generally not reinserted due to the risk of damaging the developing permanent tooth beneath the gums.
What Are the Step-by-Step Actions for a Knocked-Out Tooth?
Time is the most critical factor when a permanent tooth is knocked out. The sooner the tooth is returned to the socket or properly preserved, the higher the chance the supporting tissues can successfully reattach.
Follow this immediate action checklist:
01
Locate the tooth
Pick it up only by the white crown portion. Do not touch the root surface.
02
Clean gently
If the tooth is dirty, rinse it with milk or sterile saline for a few seconds. Do not scrub it, wipe it, or use tap water or soap.
03
Attempt reinsertion
If possible, gently place the tooth back into its socket and hold it in place by biting down on clean gauze. Do not force it.
04
Keep it moist
If reinsertion is not feasible, place the tooth in a container of cold milk or hold it in the cheek pouch to bathe it in saliva. Do not wrap the tooth in a dry tissue.
05
Seek immediate care
Go to the dentist without delay.
What Should You Do for a Chipped or Broken Tooth?
A chipped tooth is usually less time-sensitive than a completely knocked-out tooth, but it requires prompt evaluation. Rinse your mouth with warm water to clean the area and collect any broken fragments you can find. Apply a cold compress to the outside of the cheek to limit swelling if trauma was involved.
If the broken edge of the tooth is sharp, you can temporarily cover it with dental wax or sugar-free gum to protect your tongue and cheek. Schedule an evaluation promptly, even if the tooth isn’t painful, since some cracks extend below the visible surface and can worsen with normal biting pressure over time.
