Factors Affecting the Success of Replanting an Avulsed Tooth


Factors Affecting the Success of Replanting an Avulsed Tooth

Three most important factors are responsible for the success of replantation: extra-oral time, storage medium and root development.

Extra-oral time:

The lesser the extraoral dry time of the avulsed tooth, the more the chances of success of replanting the tooth. Tooth replanted with the extra-oral time of within 30 min showed no resorption of roots.

Storage media:

The avulsed tooth should be stored in a storage medium to protect the viability of tooth.  The best storage medium is milk.  Teeth can also be stored in saline or HBSS (Hanks balanced salt solution), Viaspan, contact lens solution, cell culture medium, EMT tooth saver, propolis etc.

Management of the socket

For achieving better prognosis of a replanted tooth, the socket should be taken care of by using light irrigation and gentle aspiration to eliminate any blood clot present.

Management of the root surface

The avulsed tooth should not be brushed or scraped in order to preserve the viability of the root surface.  If the root surface is already clean, replant as it is or if the root surface is dirty, rinse and clean it with tap water.

Endodontic treatment

Root canal treatment should be performed within 7-14 days of replantation and when the avulsed tooth is in its own socket.


Leaving the splint in place for 7-10 days.

Instructions to the patient 

Soft diet, brush gently with a soft brush, use of chlorhexidine mouthwash for 7 days and a regular follow should be maintained.
