Why do we extract a tooth?

Dentistry has gone through different phases throughout the ages.

In the beginning, when dentistry lacked the means to solve the different pathologies, the only existing treatment consisted of extracting the affected tooth.

Technological advances allowed us to keep teeth in the mouth for as long as possible before extracting them, moving into a non-extractionist era. But it was with the advent of the implant era that we went back to extracting teeth with a doubtful prognosis rather than trying to change the condition of the tooth and prolonging the time of extraction.

Nowadays, the attitude of dentists tends to be one of tooth preservation, only extracting those teeth that present an insurmountable prognosis or those that can be safely extracted before 3 years post-treatment.

Among the most frequent causes of removal are:

  • Fissure dividing the tooth into two fragments and extending beyond the bone line
  • Extensive caries and/or caries that go inside the gum or affect the separation of the roots of the teeth.
  • Endodontic teeth that have failed and retreatment is not possible
  • Teeth with a loss of attachment or attachment to the total bone, causing them to be excessively mobile.
  • Teeth affected by tumours that need to be extracted to ensure correct treatment of the tumour.


There is one exception, where we extract healthy teeth, and that is when the fact of extracting it interferes or improves the complete rehabilitation, damaging the final result and in the long term the fact of leaving it in the mouth.

This is why we must be as conservative as possible, as the best implant is the tooth itself, as long as it can be repaired.
