The treatment choice should be based on the degree of displacement, mobility, root formation and the ability of the child to cope with the emergency situation.

For minor extrusion (< 3mm) in an immature developing tooth, either careful reposition the tooth or leave the tooth for spontaneous alignment.

Extraction is the treatment of choice for severe extrusion in a fully formed primary tooth.

Patient instructions

  • Soft food for 1 week.
  • Good healing following an injury to the teeth and oral tissues depends, in part, on good oral hygiene. Brush with a soft brush after every meal and apply chlorhexidine 0.1 % topically to the affected area with cotton swabs twice a day for one week. This is beneficial to prevent accumulation of plaque and debris along with recommending a soft diet.

    Parents should be further advised about possible complications that may occur, like swelling, dark discoloration of the crown, increased mobility or fistula. Children may not complain about pain; however, infection may be present and parents should watch for signs of swelling of the gums and bring the child in for treatment.


  • Clinical control after 1 weeks. Clinical and radiographic control at 6-8 weeks, 6 months, and 1 year.
