    Dental injuries to deciduous(primary, baby) teeth


    Most common dental injuries in children are sustained by the upper and lower front teeth. Lets look at  the treatment  of deciduous (baby) teeth first.

    Deciduous teeth. Range of time for injury in the mouth from 8 months to 7years.

    Most 8 year olds have at least part of their adult incisors erupted

    Most common injuries are from falling over, walking, bikes, other children and toys. For all injuries please review their tetanus immunisation . we need a booster every 10 years. Any lacerations need to be looked at, major lacerations require antibiotic cover.

    If the tooth is knocked out (avulsed) DO NOT TRY AND PUT IT BACK IN. This is due to potential damage to adult tooth, infection, mobility and eventual ankylosis

    We do re-implant adult teeth but not deciduous teeth!! Keep the tooth and ring your dentist. An x-ray should be taken to assess the surrounding structures.

    Please note if the tooth is knocked out the adult tooth usually takes longer to erupt not sooner as some people expect.

    If the tooth is displaced out of its normal position

    If the tooth is pushed back behind line of other teeth. We should try and bring it back to its proper position. This can be done by a competent adult using a tissue or washcloth. We want the tooth back in its socket. Check to see if the child can close their teeth together

    If the tooth is pushed into the gum. Watch wait and see. 90% will eventually re-erupt without any treatment. It is a very good idea to have tooth looked at by your dentist and x-rayed . These teeth can injure the developing adult tooth.


    Deciduous teeth more commonly are moved bodily than fractured

    Small fractures maybe smoothed and watched

    Large fractures may require the nerve to be treated or extraction of the fractured tooth. Proper examination and x-rays are required to determine the best course of action.

    Possible scenarios in an injured tooth

    Watch for

    ·      colour changes yellow/gey/brown

    ·      gum boils, pimples on the gum

    ·      mobility

    ·      pain
