Avulsion - First aid for avulsed teeth


Dentists should always be prepared to give appropriate advice to the public about first aid for avulsed teeth. An avulsed permanent tooth is one of the few real emergency situations in dentistry. In addition to increasing the public awareness by mass media campaigns, healthcare professional, parents and teachers should receive information on how to proceed following these severe unexpected injuries. Also, instructions may be given by telephone to parents at the emergency site.

If a tooth is avulsed, make sure it is a permanent tooth (primary teeth should not be replanted).

  • Keep the patient calm.
  • Find the tooth and pick it up by the crown (the white part). Avoid touching the root.
  • If the tooth is dirty, wash it briefly (10 seconds) under cold running water and reposition it. Try to encourage the patient / parent to replant the tooth. Bite on a handkerchief to hold it in position.
  • If this is not possible, place the tooth in a suitable storage medium, e.g. a glass of milk or a special storage media for avulsed teeth if available. The tooth can also be transported in the mouth, keeping it between the molars and the inside of the cheek. Avoid storage in water.
  • Seek emergency dental treatment immediately.

The poster "Save a Tooth" is written for the public and is available in several languages: Spanish, English, Portuguese,French, Icelandic, Italian, and can be obtained at the IADT website: http://www.iadt-dentaltrauma.org.

Closed Apex:
Tooth replanted prior to the patient's arrival at the dental office or clinic

Treatment

  • Leave the tooth in place.
  • Clean the area with water spray, saline, or chlorhexidine.
  • Suture gingival lacerations if present.
  • Verify normal position of the replanted tooth both clinically and radiographically.
  • Apply a flexible splint for up to 2 weeks.
  • Administer systemic antibiotics. Tetracycline is the first choice (Doxycycline 2x per day for 7 days at appropriate dose for patient age and weight). The risk of discoloration of permanent teeth must be considered before systemic administration of tetracycline in young patients (In many countries tetracycline is not recommended for patients under 12 years of age). In young patients Phenoxymethyl Penicillin (Pen V), at an appropriate dose for age and weight, is an alternative to tetracycline.
  • If the avulsed tooth has been in contact with soil, and if tetanus coverage is uncertain, refer to physician for a tetanus booster.
  • Initiate root canal treatment 7-10 days after replantation and before splint removal.

Patient instructions

  • Soft food for up to 2 weeks.
  • Brush teeth with a soft toothbrush after each meal.
  • Use a chlorhexidine (0.1 %) mouth rinse twice a day for 1 week.

Follow-up

  • Clinical control once a week during the first month.
  • Root canal treatment 7-10 days after replantation. Place calcium hydroxide as an intra-canal medicament for up to 1 month followed by root canal filling with an acceptable material.
  • Splint removal and clinical and radiographic control after 2 weeks.
  • Clinical and radiographic control after 4 weeks, 3 months, 6 months, 1 year and then yearly thereafter.

Closed apex:
Extraoral dry time less than 60 min. The tooth has been kept in physiologic storage media (Hank's Balanced Salt Solution), milk, saline or saliva.

Treatment

  • Clean the tooth with saline.
  • Irrigate the socket with saline.
  • Examine the alveolar socket. If there is a fracture of the socket wall, reposition it with a suitable instrument.
  • Replant the tooth with gentle pressure.
  • Suture gingival lacerations if present.
  • Verify normal position of the replanted tooth both, clinically and radiographically.
  • Apply a flexible splint for up to 2 weeks.
  • Administer systemic antibiotics. Tetracycline is the first choice (Doxycycline 2x per day for 7 days at appropriate dose for patient age and weight). The risk of discoloration of permanent teeth must be considered before systemic administration of tetracycline in young patients (In many countries tetracycline is not recommended for patients under 12 years of age). In young patients Phenoxymethyl Penicillin (Pen V), at appropriate dose for age and weight, is an alternative to tetracycline.
  • If the avulsed tooth has been in contact with soil, and if tetanus coverage is uncertain, refer to physician for a tetanus booster.
  • Initiate root canal treatment 7-10 days after replantation and before splint removal.

Patient instructions

  • Soft food for up tp 2 weeks.
  • Brush teeth with a soft toothbrush after each meal.
  • Use a chlorhexidine (0.1 %) mouth rinse twice a day for 1 week.

Follow-up

  • Clinical control once a week during the first month.
  • Root canal treatment 7-10 days after replantation. Place calcium hydroxide as an intra-canal medicament for up to 1 month followed by root canal filling with an acceptable material.
  • Splint removal and clinical and radiographic control after 2 weeks.
  • Clinical and radiographic control after 4 weeks, 3 months, 6 months, 1 year and then yearly thereafter.

Closed apex:
Extraoral dry time exceeding 60 min or longer storage in non-physiologic media

Treatment

Delayed replantation has a poor long-term prognosis. The periodontal ligament will be necrotic and can not be expected to heal. The goal in doing delayed replantation is to promote alveolar bone growth to encapsulate the replanted tooth. The expected eventual outcome is ankylosis and resorption of the root. In children below the age of 15, when ankylosis occurs, and when the infraposition of the tooth crown is more than 1 mm, it is recommended to perform decoronation to preserve the contour of the alveolar ridge.


  • Remove attached necrotic soft tissue with gauze.
  • Root canal treatment can be performed prior to replantation, or it can be done 7-10 days later.
  • Immerse the tooth in a 2% sodium fluoride solution for 20 min.
  • Irrigate the socket with saline.
  • Examine the alveolar socket. If there is a fracture of the socket wall, reposition it with a suitable instrument.
  • Replant the tooth with gentle pressure.
  • Suture gingival lacerations if present.
  • Verify normal position of the replanted tooth clinically and radiographically.
  • Stabilize the tooth for 4 weeks using a flexible splint.
  • Administer systemic antibiotics. Tetracycline is the first choice (Doxycycline 2x per day for 7 days at appropriate dose for patient age and weight). The risk of discoloration of permanent teeth must be considered before systemic administration of tetracycline in young patients (In many countries tetracycline is not recommended for patients under 12 years of age). In young patients Phenoxymethyl Penicillin (Pen V), at an appropriate dose for age and weight, is an alternative to tetracycline.
  • If the avulsed tooth has been in contact with soil, and if tetanus coverage is uncertain, refer to physician for a tetanus booster.

Patient instructions

  • Soft food for up to 2 weeks.
  • Brush teeth with a soft toothbrush after each meal.
  • Use a chlorhexidine (0.1%) mouth rinse twice a day for 1 week.

Follow-up

  • Clinical control once a week during the first month.
  • If root canal treatment was not performed at the initial treatment session then root canal treatment should be performed 7-10 days after replantation.
  • Splint removal and radiographic control after 4 weeks.
  • Clinical and radiographic control after 4 weeks, 3 months, 6 months, 1 year and yearly thereafter.

Open apex:

Treatment

Delayed replantation has a poor long-term prognosis. The periodontal ligament will be necrotic and not expected to heal. The goal in doing delayed replantation of immature teeth in children is to maintain alveolar ridge contour. The eventual outcome is expected to be ankylosis and resorption of the root. It is important to recognize that if delayed replantation is done in a child, future treatment planning must be done to take into account the occurrence of tooth ankylosis and the effect of ankylosis on the alveolar ridge development. When ankylosis occurs, and when the infraposition of the tooth crown is more than 1 mm, it is recommended to perform decoronation to preserve the contour of the alveolar ridge.


  • Remove attached necrotic soft tissue with gauze.
  • Root canal treatment can be performed prior to replantation through the open apex.
  • Immerse the tooth in a 2% sodium fluoride solution for 20 min.
  • Irrigate the socket with saline.
  • Examine the alveolar socket. if there is a fracture of the socket wall, reposition it with a suitable instrument.
  • Replant the tooth with gentle pressure.
  • Suture gingival lacerations if present.
  • Verify normal position of the replanted tooth clinically and radiographically.
  • Stabilize the tooth for 4 weeks using a flexible splint.
  • Administer systemic antibiotics. For children 12 years and younger: Penicillin V at an appropriate dose for patient age and weight.
  • If the avulsed tooth has been in contact with soil or if tetanus coverage is uncertain, refer to physician for evaluation of the need for a tetanus booster.

Patient instructions

  • Soft food for up to 2 weeks.
  • Brush teeth with a soft toothbrush after each meal.
  • Use a chlorhexidine (0.1%) mouth rinse twice a day for 1 week.

Follow-up

  • If root canal treatment was not performed at the initial treatment session then root canal treatment should be performed 7-10 days after replantation.
