Dry Socket Information and Infographic

Dry socket (medical term: Alveolar osteitis) is a common post-extraction complication, particularly after wisdom tooth removal. It occurs when the blood clot that normally forms in the tooth socket either dissolves prematurely or becomes dislodged, exposing the underlying bone and nerves.

Pathophysiology

After an extraction, a stable blood clot is essential for proper healing. In dry socket:
- The clot is lost or fails to form
- Fibrinolysis increases (often due to bacterial activity)
- Bone becomes exposed → intense nociceptive response

Clinical Symptoms

Typically appear 2–4 days post-extraction:
- Severe, radiating pain (can extend to ear, temple, neck)
- Empty-looking socket (often with visible bone)
- Foul odor or bad taste (halitosis)
- Delayed healing
- Minimal swelling (unlike infection)

Risk Factors

- Traumatic or difficult extraction (especially impacted molars)
- Smoking (nicotine reduces blood flow and disrupts clot stability)
- Poor oral hygiene
- Oral contraceptives (estrogen increases fibrinolytic activity)
- Previous history of dry socket
- Excessive rinsing/spitting immediately after extraction

Management

Dry socket is not an infection, so treatment is symptomatic and local:
- Gentle irrigation with saline or chlorhexidine
- Placement of medicated dressings (e.g., eugenol-based)
- Analgesics (NSAIDs or stronger if needed)
- Re-evaluation every 24–48 hours until symptoms resolve

Antibiotics are not routinely indicated unless secondary infection is suspected.

Prevention

- Atraumatic extraction technique
- Pre/post-op chlorhexidine rinses
- Avoid smoking for at least 72 hours
- Do not rinse vigorously or use straws post-extraction
- Patient compliance with post-op instructions
