Tooth extraction

When no other option is available to save a tooth, its removal is necessary. Patients often are frightened about dental extractions, even more than other surgical procedures. Nowadays, modern techniques and the use of local anesthesia makes extractions a routinary procedure without discomfort to the patient.


Tooth extraction is a dental procedure performed in clinical conditions where there isn’t any other treatment.The most common cause for a tooth extraction is the destruction by caries, followed by periodontal disease. However, there are other situations where it is neccessary the extraction of a tooth:

- Teeth affected by fractures: when trauma occurs in the face, it may happen that the fracture line of bone affects a tooth and its removal is necessary. Likewise during trauma, a fracture of tooth can occur. When this breakdown occurs at the level of the root under the gum, it is not possible to restore the tooth, so it has to be extracted.

- Extraction of teeth for orthodontic treatment: When teeth malposition is present and a orthodontics treatment is planned, sometimes there is not enough space to correct the position of the teeth. In these cases the only way to get enough space for proper placement is the extraction of a tooth even if it is healthy (usually the first premolars).

- Extraction of teeth to facilitate the construction of a prosthesis: sometimes a tooth is located in a bad position, making difficult the placement of a dental prosthesis where a large amount of teeth are going to be involved.

- Retained baby teeth: When teeth do not fall in due time, they can cause an alteration in the final tooth position, so these teeth should be extracted.

- The teeth as source of infection: there are situations where chronic tooth infection may be related to the overall patient´s health. In these cases, if other treatment is not possible, the tooth is removed and the area is cleaned.

- Tooth impaction: These are teeth that have not erupt in their normal eruption cicle and are retained in an incorrect position. The most common impacted teeth are the wisdom teeth and canines, being most common the superior ones.
