Tooth extractions are generally performed to remove a damaged or unhealthy tooth from its socket in the jaw bone. They are necessary primarily due to severe decay, advanced periodontal disease or irreparable damage caused by trauma. Decay, often resulting from poor oral hygiene, can weaken the tooth structure, making extraction the only viable option. Advanced gum disease (periodontal disease) can lead to infection and damage to the surrounding tissues, necessitating extraction to prevent further complications. Trauma, such as accidents or injuries, can cause irreparable damage to the tooth, mandating its removal to maintain oral health.

In some cases, overcrowding or impaction, commonly seen with wisdom teeth, may warrant extraction to alleviate pain or prevent future issues. 

In preparation for orthodontic procedures, some people may require the removal of certain teeth to achieve the desired results effectively.

Your dentist will discuss all of your treatment options and the ways they will impact you. If you do require an extraction, the dentist will discuss options to replace the extracted teeth, if necessary.
