Avulsed deciduous tooth (lost baby tooth)

baby teeth falling out

Summary

Losing a baby tooth is a normal part of growing up and generally is absolutely nothing to worry about.

Children generally start losing their baby teeth at 6 years old but this can vary greatly. Girls often lose their teeth earlier than boys but there is a large normal variation between children.

Here is a schedule for deciduous tooth eruption (when it comes through) and exfoliation (when they are lost)

Lower Teeth

 EruptionExfoliation
Central incisor6 to 10 months6 to 7 years
Lateral incisor10 to 16 months7 to 8 years
Canine17 to 23 months9 to 12 years
First molar14 to 18 months9 to 11 years
Second molar23 to 31 months10 to 12 years

Upper Teeth

 EruptionExfoliation
Central incisor8 to 12 months6 to 7 years
Lateral incisor9 to 13 months7 to 8 years
Canine16 to 22 months10 to 12 years
First molar13 to 19 months9 to 11 years
Second molar25 to 33 months10 to 12 years

If the deciduous tooth was mobile before it was lost then generally this can be considered normal. If the tooth was not loose then it is considered early loss. This can delay the eruption of the adult successor tooth. It is also important to check all of the root has come out, if there is root left in place then it would be wise to get the area checked by a dentist.

Home care advice

Even if a deciduous tooth comes out before its time it is generally not an emergency. However it is important to check that the tooth has not been pushed up into the gum. If this is the case then an emergency appointment IS required so check whether the tooth could be damaging/or have damaged the underlying adult tooth.

  • Check all the tooth has come out - if not see intrusive luxation if you think the tooth has been pushed into the gums or complicated fracture if tooth is broken
  • Check tooth has not been swallowed - if concerned that the tooth has been inhaled into the lungs seek urgent medical assistance 
  • If area is bleeding then bite down on handkerchief for 15-20 minutes, if unable to stop bleeding then seek dental or medical advice
  • Keep area clean with salt water rinses
