Identify 7 local causes of delayed healing after tooth extraction?

1. Infection: If bacteria enter the extraction site, it can lead to an infection that delays the healing process.
2. Poor oral hygiene: Failure to maintain proper oral hygiene after tooth extraction can increase the risk of infection and delay healing.
3. Smoking: Smoking can impair blood flow and reduce oxygen supply to the extraction site, slowing down the healing process.
4. Diabetes: Uncontrolled diabetes can affect the body's ability to heal, including after tooth extraction.
5. Medications: Certain medications, such as corticosteroids or immunosuppressants, can interfere with the healing process.
6. Poor nutrition: A diet lacking in essential nutrients, such as vitamins C and D, can hinder the body's ability to heal properly.
7. Trauma or excessive force: Applying excessive force during the extraction procedure or trauma to the extraction site afterwards can delay healing.
