- Dry socket happens when the blood clot in the hole left by a removed tooth does not form properly or comes away, leaving the bone exposed. It is painful but treatable.
- The main sign is pain that gets worse a few days after an extraction instead of better, often with bad breath or a bad taste. Sources give different timings, from the first day or two to about 10 days.
- Smoking, a difficult extraction, a lower back tooth or wisdom tooth, a previous dry socket and the contraceptive pill all make it more likely.
- Contact your dentist if you think you have it. They can clean the socket and place a soothing dressing, and the pain usually improves quickly after treatment.
- Trouble breathing or swallowing, spreading swelling, a high temperature or bleeding that will not stop need urgent help.
After a tooth is taken out, a blood clot normally forms in the socket (the hole in the jawbone where the tooth was). healthdirect Australia explains that this clot protects the bone and nerves underneath. Dry socket, also called alveolar osteitis, is what happens when the clot is lost or does not form well. The bone and nerve are left exposed, which healthdirect says causes extreme pain and can lead to infection. For general aftercare, see having a tooth out.
How common is it?
healthdirect says dry socket is common and happens in about 1 in 20 tooth extractions. A Cochrane review (a large summary of the research) gives a wider range: from 1% to 5% of routine extractions to upwards of 30% of wisdom teeth removed surgically. Both healthdirect and Cochrane say it is more likely after a lower wisdom tooth is removed.
When does it happen?
Some pain after an extraction is normal. What marks out dry socket is pain that becomes more severe instead of settling. The Oral Health Foundation (UK) describes "increasing pain a few days after the extraction".
Sources give different timings, so do not rule it out because of timing alone:
- healthdirect: within 1 to 3 days of the extraction
- the Cochrane review: 2 to 3 days after
- the Oral Health Foundation: sometimes 3 to 4 days after
- East Sussex Healthcare NHS Trust: usually 3 to 5 days after
- Hull University Teaching Hospitals NHS Trust: pain can return 3 to 10 days after surgery
- Bedfordshire Hospitals NHS Trust: symptoms usually start in the first 24 to 48 hours
For comparison, Bedfordshire Hospitals says ordinary pain after an extraction usually peaks on the second or third day and then improves.
What are the symptoms?
healthdirect lists:
- severe, ongoing throbbing pain, which may spread to the ear or eye on the same side of the face
- bad breath and an unpleasant taste in your mouth
- a slight fever
- swelling around the socket
healthdirect adds that you may see exposed bone in the socket instead of a dark blood clot, sometimes with greyish tissue over it.
What causes it, and who is at risk?
healthdirect says the breakdown of the clot may be caused by an underlying infection in the mouth, trauma from the extraction, or problems with the jawbone. It says you are more likely to get dry socket if you:
- smoke
- have had dry socket before
- had a difficult extraction
- take the oral contraceptive pill
- do not have good dental hygiene
- had a tooth taken from the lower jaw, especially a molar or wisdom tooth
Bedfordshire Hospitals adds vaping and long or complex extractions, and the Better Health Channel (Victoria) mentions people who have difficulty healing. MedlinePlus (the US National Library of Medicine) says drinking through a straw can disturb the clot and cause dry socket.
Is it an infection? The sources describe it differently. The Cochrane review says dry socket "is not bacterial in origin". Hull University Teaching Hospitals calls it "a kind of local infection" caused by food collecting in a socket where the clot has not formed properly, and the Oral Health Foundation says the bone becomes infected.
What will a dentist do?
healthdirect says a dentist can usually diagnose dry socket by examining you, though tests may be needed to rule out osteomyelitis (a bone infection).
Treatment described by healthdirect, the American Dental Association (ADA) and Bedfordshire Hospitals includes:
- Cleaning the socket, flushing out food and debris.
- A medicated or soothing dressing placed in the socket. The ADA says the dressing may be changed daily until the pain eases and the socket starts to heal.
- Rinses at home. healthdirect says your dentist will ask you to rinse with mouthwash or salt water.
- Pain relief, which your dentist may prescribe.
Antibiotics: the sources differ. The Oral Health Foundation says your dentist may dress the socket and/or give antibiotics. Hull University Teaching Hospitals says antibiotics are not usually necessary.
healthdirect says the condition should improve quickly after treatment, and to return to your dentist or doctor if you still have pain after 3 weeks. The Cochrane review found the evidence on which dressing works best is very uncertain.
Looking after yourself until you are seen
- Contact your dental practice (healthdirect, Oral Health Foundation).
- Painkillers. Bedfordshire Hospitals suggests paracetamol and/or ibuprofen if you have no allergies to them. Check the leaflet or ask a pharmacist whether they suit you; our toothache guide lists the main cautions.
- About aspirin, sources differ. The ADA says a dentist may prescribe an anti-inflammatory painkiller such as aspirin or ibuprofen for dry socket. The Oral Health Foundation and Kent Community Health NHS Foundation Trust advise avoiding aspirin after an extraction because it can increase bleeding. Ask your dentist or pharmacist. If you take aspirin prescribed for a heart condition, Kent Community Health says to carry on with it and tell your dentist.
- Do not smoke. The ADA says smoking and other tobacco use can delay healing. See smoking, vaping and oral health.
- Keep the area clean and leave it alone. Keep your tongue and fingers away from the socket (Kent Community Health), eat soft food and chew on the other side (healthdirect).
Can dry socket be prevented?
healthdirect's tips are to rinse and spit gently, avoid smoking, and follow your dentist's instructions. Having a tooth out covers aftercare in more detail.
- Protect the clot. healthdirect says not to rinse for the first 24 hours, then rinse gently with warm salt water after meals and before bed. MedlinePlus (US) says to wait about 3 days before rinsing and spitting.
- Avoid straws for at least 24 hours (MedlinePlus). The Better Health Channel also advises against excessive rinsing or spitting.
- Do not smoke. Advice on how long varies: healthdirect says the first 24 hours, Kent Community Health 24 to 48 hours, the Better Health Channel 48 hours after wisdom tooth surgery, Bedfordshire Hospitals at least 72 hours (smoking or vaping), and Hull University Teaching Hospitals ideally at least 5 days.
What your dentist may do. healthdirect says your dentist may give you a medicated mouth rinse before and after the extraction, or put a special gel in the socket. The Cochrane review found moderate-certainty evidence that chlorhexidine (an antiseptic) probably reduces dry socket, either as a mouthwash used before the extraction and again from 24 hours afterwards, or as a gel placed in the socket. The rinses caused some minor side effects, including taste changes, tooth staining and mouth inflammation. Use them only as your dentist advises.
- Your pain is getting worse a few days after an extraction instead of better, or you think you have dry socket (healthdirect, Oral Health Foundation).
- You have pain with a bad taste in your mouth, a high temperature or feel unwell. After wisdom tooth removal, the NHS says to ask for an urgent dentist appointment or contact NHS 111.
- You have facial swelling (healthdirect), severe swelling or pus from the socket, or fever or chills (MedlinePlus).
- You still have pain 3 weeks after treatment for dry socket (healthdirect).
- The Oral Health Foundation says to get advice quickly for swelling that is getting worse, difficulty swallowing or breathing, a high temperature, or severe bleeding that will not stop.
- UK: the NHS says go to A&E for toothache with swelling around your eye or neck, or swelling in your mouth or neck that makes it hard to breathe, swallow or speak. Kent Community Health says heavy or prolonged bleeding out of hours needs A&E.
- Elsewhere: call your local emergency number for trouble breathing or swallowing. See dental emergencies.
Frequently asked questions
How do I know if it is dry socket or normal healing?
Hull University Teaching Hospitals says normal pain should gradually improve day by day. healthdirect says to contact your dentist if you have ongoing intense pain a few days after the extraction, or think you may have dry socket. Bad breath and a bad taste are other clues.
Will dry socket go away on its own?
healthdirect says it can heal by itself after a few weeks, but the pain in that time can be intense and treatment usually brings relief quickly.
Is dry socket dangerous?
healthdirect says the main complication is that the wound takes longer to heal. Bedfordshire Hospitals lists swelling, discharge, fever and feeling generally unwell among the signs of infection after an extraction, so contact your dentist if you have them.
