Emergency Medical Minute Podcast 810: Tooth Replantation
Contributor: Jarod Scott, MD
Educational Pearls:
- There is a 1-hour window for tooth replantation in ED
- Cold milk is often best transport media unless there is access to specialized solutions (Hank's Balanced Solution)
- Goal is to preserve periodontal ligament
- Soaking in tap water should be avoided as it will lyse cells of periodontal ligament
- If oral surgeon is rapidly available, have them perform replantation
- Do not delay replantation to wait for an oral surgeon to become available
- Steps in tooth reimplantation
- Disturb the socket as little as possible
- Handle tooth only by crown, don't touch root
- Rinse tooth gently with tap water or saline, do not scrub it
- Tooth should click back in place and remain stable
- Don't manipulate after reimplantation
- It may take weeks to determine if the tooth will survive
- Studies have shown that replantation performed within one hour has a significantly better prognosis than those taking place after a greater amount of time has passed
