Most extractions hurt least on the day of the extraction and a little less every day after that. Dry socket is the exception, and the shape of it is what gives it away: you feel better, then somewhere between the second and the fourth day the pain comes back worse than it was at the start, and painkillers that worked on Monday do nothing by Wednesday.
It is not an infection, and in most cases it is not something you did wrong. It is a healing step that has gone missing. It is also one of the few dental problems where the visit takes ten minutes and the relief is close to immediate, which is the main reason this page exists: people put up with it for days believing there is nothing to be done.
What dry socket actually is
When a tooth comes out, the socket fills with a blood clot. That clot is not a scab getting in the way of healing, it is the healing: it covers the bone and the nerve endings underneath, and new tissue grows in over it.
Dry socket, which a dentist may call alveolar osteitis, is what happens when that clot breaks down or is lost too early. Bone and nerve are left exposed to air, food and cold water. That is why the pain is out of all proportion to a small hole in the gum, and why it often spreads up the jaw towards the ear or the temple on the same side.
It is most common after lower back teeth, and most common of all after a difficult lower wisdom tooth. If your extraction was straightforward and near the front, dry socket is unlikely.
How to tell it apart from ordinary healing
Ordinary healing after an extraction is sore, and the soreness fades. Dry socket reverses that direction, and the timing is the clearest signal you have.
- Day one and two are the worst, then steadily better: that is normal healing
- Better, then sharply worse on day two to four: that pattern is dry socket
- Pain that spreads to the ear, eye or temple on the same side
- A bad taste or smell that mouthwash does not touch
- A socket that looks empty, sometimes with pale bone visible, rather than filled with a dark red clot
- Painkillers that helped at first and now barely register
Fever, swelling and the difference that matters
Dry socket hurts, but it does not usually make you ill. An infection does. That is the line worth knowing, because it changes how quickly you need to be seen and by whom.
A swelling that is growing, a fever, pus, or difficulty swallowing or opening your mouth point to infection rather than a lost clot, and they need same day attention. Swelling that reaches towards your eye or under your jaw, or any trouble breathing or swallowing, is an emergency room matter tonight rather than a dental appointment tomorrow. Our guide to the signs of a tooth abscess covers those in more detail, and there is a wider one on what counts as a dental emergency.
Plain dry socket, by contrast, is severe pain with a normal temperature and no spreading swelling. Unpleasant, not dangerous.
What a dentist does about it
Ring the practice that took the tooth out first. This is their aftercare, they will usually fit you in the same day, and there is often no charge for it.
The visit is short. They irrigate the socket to flush out debris, then place a medicated dressing, usually a small strip of paste on a carrier, directly into it. Most people feel the difference within minutes, because the dressing covers the exposed bone and carries something for the pain.
The dressing may be changed once or twice over the following days, and the socket then heals the ordinary way. Antibiotics are not usually part of it, because there is no infection to treat, and a dentist who declines to prescribe them here is not fobbing you off.
If the practice that did the extraction cannot see you, any dentist can place a dressing. You can find one near you in the directory, and it is worth saying on the phone that you had an extraction three days ago and think it is dry socket. Practices keep slots for exactly this.
What helps until you are seen, and what makes it worse
Nothing at home fixes dry socket, because the fix is a dressing in the socket. These make the wait more bearable without setting the healing back.
- Take the painkiller you would normally take for pain, at the dose on the packet
- Rinse gently with warm salt water after meals, letting it fall out of your mouth rather than spitting
- Eat on the other side, and keep to soft food that does not need much chewing
- Sleep with your head a little higher than usual
- Do not smoke or vape, which is the single most useful thing on this list
- Do not use a straw, and do not swill, spit or rinse forcefully
- Do not poke the socket with a tongue, a finger or an interdental brush
- Do not pack it with clove oil on cotton wool yourself: too much clove oil burns the gum, and it is easy to leave the cotton behind
What makes it more likely next time
Dry socket follows somewhere around two to five in every hundred routine extractions, and more after difficult lower wisdom teeth. Some of what raises the odds is out of your hands, and some is not.
Smoking is the biggest thing you control, both the suction and the chemistry, and stopping for the first few days after an extraction genuinely lowers the risk. The contraceptive pill raises it slightly. So does having had dry socket before, a difficult or surgical extraction, and disturbing the site on the first day.
If you are having another tooth out and you have had dry socket before, say so when you book. It changes the aftercare advice you are given, and some dentists place a dressing at the time for people with a history of it. Our guide on what to expect from wisdom teeth removal covers the rest of that recovery.
The short version
- The tell is the timing: better, then sharply worse two to four days after the extraction.
- It is exposed bone rather than an infection, which is why the pain is severe but you are not ill.
- Fever, growing swelling or pus mean infection instead, and that needs same day attention.
- A dentist irrigates the socket and places a dressing, and it usually helps within minutes.
- Ring the practice that took the tooth out first: this is aftercare, and often free.
- Not smoking, not using a straw and not swilling are the three things that protect the clot.

Frequently asked
How long does dry socket last if I do nothing?
Usually seven to ten days, with the worst of it in the first few. There is no reason to wait it out. A dressing takes a few minutes to place, and most people feel the difference before they leave the chair.
Can dry socket heal on its own?
Yes, eventually. The socket fills in with new tissue whether or not it is dressed, and the pain fades as it does. Treatment does not speed the healing much. It treats the pain, which is the part that is hard to live with.
Is dry socket an emergency?
It is urgent rather than an emergency. Get seen the same day or the next day if you can. A fever, a swelling that is growing, or trouble swallowing or opening your mouth is different, and needs attention tonight.
What does dry socket look like?
The socket looks empty rather than filled with a dark red clot, and you may see pale bone at the bottom of it. It is easier to recognise by the pain and the timing than by looking, so do not rely on a mirror.
Can I get dry socket a week after the extraction?
It is unusual. Dry socket almost always starts on the second to fourth day. Pain that begins a week or more later is more likely to be an infection, or a small piece of bone working its way out, and both are worth a phone call.
