Tooth extractions are important for several reasons:

1. Severe Decay or Damage: When a tooth is extensively decayed or damaged beyond repair, extraction may be necessary to prevent further oral health complications and pain.

2. Wisdom Teeth Removal: Wisdom teeth often lack sufficient space to properly erupt, leading to impaction, crowding, or infection. Extraction of impacted wisdom teeth can prevent discomfort and potential oral health issues.

3. Orthodontic Treatment: Sometimes, tooth extractions are necessary as part of orthodontic treatment to create space and facilitate proper alignment of the remaining teeth.

4. Infection or Abscess: If a tooth infection or abscess cannot be effectively treated with root canal therapy or antibiotics, extraction may be required to eliminate the infection and prevent its spread.

5. Periodontal Disease: In advanced stages of periodontal (gum) disease, tooth extraction may be necessary if the supporting structures around the tooth are significantly damaged and cannot be restored.
