What to Do When You Knock Out a Tooth: A Step-by-Step Guide
TL;DR — Quick Summary
If a permanent tooth is knocked out: 1) Pick it up by the crown only (never the root), 2) Rinse gently with milk or saline — never scrub it, 3) Try to place it back in the socket, 4) If you can’t, store it in milk or saliva, 5) Get to a dentist within 30 minutes. The faster you act, the higher the chance of saving the tooth. Call Smile Avenue immediately at (832) 648-1756 for same-day emergency care.
Time Is Everything
A knocked-out permanent tooth is one of the most time-sensitive dental emergencies. If you act within the first 30 minutes, there’s a strong chance the tooth can be reimplanted and saved. After 60 minutes outside the mouth, the survival rate drops significantly.
Step-by-Step: What to Do Right Now
Step 1: Find the Tooth and Pick It Up Correctly
Pick up the tooth by the crown (the white part you see when you smile) — never touch the root. The root surface has delicate cells called periodontal ligament cells that are essential for reattachment.
Step 2: Rinse Gently (If Dirty)
If the tooth is dirty, rinse it very gently with milk or saline solution. Do not:
- Scrub the tooth
- Use soap or chemicals
- Wrap it in tissue or let it dry out
- Use tap water for more than a few seconds (the chlorine damages root cells)
Step 3: Try to Reimplant It
If possible, gently place the tooth back into the socket. Bite down on a clean cloth to hold it in place. This is the single best thing you can do to save the tooth.
Step 4: If You Can’t Reimplant, Keep It Moist
Place the tooth in one of these (in order of preference):
- Milk — the best readily available storage medium
- Saliva — tuck it between your cheek and gum
- Saline solution — if available
- Never let the tooth dry out or store it in plain water
Step 5: Get to a Dentist IMMEDIATELY
Call Smile Avenue’s emergency line at (832) 648-1756. We offer same-day emergency appointments and will prioritize reimplantation cases.
What the Dentist Will Do
Your emergency dentist will:
- Clean the socket and assess for fractures
- Reimplant the tooth (if it hasn’t been reimplanted already)
- Splint the tooth to adjacent teeth for 1–2 weeks while it re-stabilizes
- Prescribe antibiotics and anti-inflammatory medication
- Schedule follow-up appointments to monitor healing
What If the Tooth Can’t Be Saved?
If too much time has passed or the tooth is damaged beyond reimplantation, the best long-term replacement is a dental implant. Implants look, feel, and function exactly like natural teeth and can last a lifetime.
Prevention Tips
- Wear a mouthguard during contact sports
- Wear a mouthguard during recreational activities (biking, skateboarding)
- Address loose teeth promptly — they’re more susceptible to being knocked out
- Schedule regular dental check-ups to maintain strong tooth structure
