Tooth discolouration after trauma is quite an expected possibility. Discolouration of a tooth can occur in children from sudden fall or accidents, when the tooth receives a severe shock. The extent of discolouration of the tooth after trauma depends upon the severity of the shock or injury. Post trauma internal bleeding in the pulp chamber is mainly responsible for tooth discoloration. Blood gets into the dentinal nerves and gets trapped into the pulp, staining the dentin.



A tooth gets discoloured and turns black or grey within a few days post trauma, and the discolouration disappears automatically in case of a mild shock. On the contrary, a severely traumatised tooth may darken gradually with each passing day indicating poor functioning of the dentinal nerves. The tooth ultimately loses its vitality within a few months or a year and will require nerve treatment. Only the expert hands of an experienced orthodontist can cure the discolouration of a traumatised tooth.


Tooth Discolouration

Tooth Discolouration after Trauma:

 

  • Discolouration of tooth following a trauma is a common event, and extreme preciseness is required in treating the discoloured tooth.
  • Mild traumatic shock can revive the natural tooth colour within few weeks, while discolouration of a severely traumatised tooth can continue for months.
  • The main treatment of tooth discolouration involves the careful removal of the stained dentin and the pulp horns. Complete removal of the pulp horns is often very difficult due to inaccessibility and requires expert hands to carry out the treatment.
  • Bleaching is also an option for treating tooth discoloration after trauma.
  • Laser Doppler Flowmetry is often applied to assess the blood flow in the traumatised tooth. It helps in proper diagnosis.
  • Symptomatic and radiographic evaluations provide the best methods of diagnosis in treating tooth discoloration after trauma.
  • In case of children, colour change of the traumatised tooth from yellow to brownish yellow generally indicates calcification and obliteration of the dental pulp, and in most cases it regains its natural colour within few days, without any treatment.
  • If the colour of the traumatised tooth changes to black, indicates the death of the dental pulp or necrosis in most of the cases. It can be treated either with root canal therapy or by extracting that tooth.
  • Pink coloured tooth after trauma indicates the presence of blood pigments in the dental pulp and that requires regular monitoring by an experienced orthodontist.



Discolouration of tooth after trauma can occur both in adults and children; children being the worst sufferers from traumatised tooth due to accidents at home and in school. Traumatised tooth in adults mostly occurs from various sporting activities affecting the incisors. Discolouration of tooth after trauma requires sometimes requires advanced medical treatment in order to preserve the traumatised tooth.
