Common Reasons for Tooth Extraction

Tooth extraction is a minor dental operation which involves removing a tooth or teeth from the mouth. Here are three of the commonest reasons why teeth extractions are performed.

Preparation for dental prosthetics

Teeth may be extracted to make space in the mouth for dentures, bridges, crowns or implants.

Removing non-restorable teeth

Tooth extraction is necessary when a tooth is damaged beyond repair. A tooth may reach this stage because of extreme dental decay, fracture, or trauma. A tooth may also become non-restorable if the pulp or nerve is so infected that neither antibiotics nor root canal therapy can restore the tooth to health. Alternatively, gum disease can destroy the tissues and the alveolar bone supporting the teeth causing the teeth to become loose.

To resolve abnormal tooth development.  

Sometimes, for whatever reason, teeth may develop in a defective way, creating potentially serious health risks. Malposed teeth (growing in a crooked or abnormal position) may damage the soft tissue of the cheek. Moreover, because plaque accumulates more profusely on malposed teeth, and because the irregular gaps created by these teeth invite food impaction, malposed teeth increase the risk of cavities and gum disease.

Another problem related to abnormal tooth development is a crowded mouth. If a person’s jawbones are too small or if there are extra teeth, then there will not be sufficient space for other teeth to erupt, leading to impacted or embedded teeth trapped beneath the gum and bone. Complications of impacted and embedded teeth include tooth decay, cyst formation, and gum disease. Impacted and embedded teeth can also push against surrounding teeth, throwing off teeth alignment.

For the above reasons, dental extraction is recommended to remove malposed, extra, impacted, and embedded teeth.
