What to Do If You Knock Out a Tooth
The first hour is critical — here is exactly what to do and what to avoid
Knocked-out permanent teeth are one of the most time-critical dental emergencies. The window for successful reimplantation is approximately one hour from the moment the tooth comes out. What you do in those first 60 minutes determines whether the tooth can be saved. This post is a practical step-by-step guide. If this is happening to you right now, call (630) 549-7916 immediately and follow the steps below while you get to our office in St. Charles, IL. From Dr. Aqil Valika at Bliss Dental.
Step 1: Find the tooth. Pick it up by the crown only — the white chewing surface. Never touch the root (the yellow-ish part that was below the gumline). The root surface has thousands of cells essential for reattachment, and they are damaged by handling.
Step 2: If the tooth is dirty, rinse gently. Use saline or milk if you have them. Plain cool water as a last resort for 10 seconds maximum. Do not scrub. Do not use soap or any cleaning product. Do not dry it with a towel. The goal is to rinse off visible dirt without damaging the root cells.
Step 3: If you can, place it back in the socket. Push gently — do not force. If it goes in, bite gently on a clean cloth or gauze to hold it. If it does not go in easily, do not force it. Move to step 4.
Step 4: Store the tooth properly. Best storage: in a small container of milk. Acceptable: in saliva (place between cheek and gum if you can do so safely; otherwise spit into a small clean container). Never plain water — water destroys the root cells the tooth needs to reattach. The wrong storage is sometimes worse than the right storage at saving the tooth.
Step 5: Get to a dentist immediately. Call (630) 549-7916 and tell the front office it is a knocked-out tooth. They will route you to the next available slot — typically within 30 to 60 minutes. Total time from injury to dentist: ideally under 1 hour. The reimplantation success rate at 30 minutes is 70 to 90%; at 60 minutes about 50 to 70%; at 2 hours about 20 to 40%. Every minute counts.
One important exception: knocked-out baby teeth. Do not reimplant a knocked-out baby tooth — the procedure can damage the underlying permanent tooth bud. Save the tooth and bring it to the dentist for examination. The permanent tooth will erupt naturally on its normal schedule.
