Dry Socket (Alveolar Osteitis)

Dry socket, clinically called alveolar osteitis, is a painful complication of tooth extraction. It happens when the blood clot that should fill the empty socket fails to form, breaks down early or is dislodged, leaving the bone of the socket exposed. It typically appears a few days after the extraction, not on the day itself.

Why It Matters

The blood clot is the first stage of healing: it protects the bone and nerve endings and acts as a scaffold for new tissue. Without it, the socket heals more slowly and the exposed bone is very painful. Dry socket is not usually an infection and is not dangerous in itself, but the pain rarely settles with ordinary painkillers alone, so it needs to be seen by a dentist.

Clinical Details

• Timing: Pain usually starts around 2–5 days after the extraction, often after an initial period when recovery seemed normal.
• Symptoms: Severe, throbbing pain at the extraction site that may spread to the ear, eye or temple on the same side; an empty-looking socket with visible greyish-white bone instead of a dark clot; bad breath and an unpleasant taste.
• Higher-risk situations: Difficult or surgical extractions, especially of a lower wisdom tooth; smoking; a previous dry socket; and poor oral hygiene. Some studies also link the oral contraceptive pill to a higher risk.
• Diagnosis: Based on the timing of the pain and examination of the socket. An X-ray may be taken to rule out a retained root fragment or a bone problem.
• Treatment: The dentist gently rinses the socket to remove food debris and places a medicated dressing that soothes the exposed bone. The dressing may need to be changed over the following days. Pain relief is advised alongside this.
• Healing: Once the socket is covered, pain usually eases quickly, and the socket then continues to heal over the following one to two weeks.

FAQ

What does dry socket look like?

Instead of a dark red clot, the socket looks empty or dry, and you may see whitish or grey bone at the bottom. Food may also collect in it. A normal healing socket has a dark clot that gradually turns paler as new tissue forms.

How do I know if I have dry socket?

The key sign is pain that gets worse rather than better a few days after the extraction, especially if it spreads towards the ear and is not controlled by painkillers. Some aching and swelling in the first 1–2 days is normal.

Will dry socket heal on its own?

The socket will eventually heal, but this takes longer and the pain can be severe in the meantime. Contact your dentist so the socket can be cleaned and dressed.

How can I prevent dry socket?

Follow the aftercare advice you are given. In the first days after an extraction: do not smoke or vape, avoid rinsing vigorously or spitting forcefully, do not drink through a straw, avoid alcohol and very hot drinks, and stick to soft food chewed on the other side. Keep the rest of your mouth clean.

When should I contact the dentist?

If pain increases after the first two or three days, if you notice a bad taste or smell from the socket, or if you have swelling, a fever or bleeding that will not stop.
