If you've had a tooth out and the pain suddenly gets worse a few days later, dry socket is often the reason. It's one of the more common issues that can happen after wisdom teeth removal, particularly with the lower ones. It's treatable, though, and your dentist can usually settle the pain quickly. This article explains what dry socket is, how to spot it, what brings it on, and how to lower your chances of getting it. At ArtSmiles, we want you to know what's normal and what's worth a phone call.
What is dry socket?
Dry socket is a fairly common complication that can happen after a tooth is removed. The medical name is alveolar osteitis, but most people just call it dry socket.
Here's what's going on underneath. When a tooth comes out, a blood clot forms in the empty socket. That clot is doing an important job: it protects the bone and the nerve endings while the area heals. Dry socket happens when that clot dislodges or dissolves too early. The bone and nerves underneath are left exposed, and that's what causes the pain.
It tends to affect lower wisdom teeth more than other extractions. If you'd like to understand the procedure itself, our guide to wisdom teeth removal walks through what to expect.
Dry socket symptoms
The main sign is pain. Usually it's a sudden increase in pain a few days after the surgery, often just when you'd expect to be feeling better. The pain can be severe and throbbing.
Other things you might notice:
Pain that spreads to your ear, eye, temple or neck on the same side
An empty-looking socket where the clot has gone, sometimes with visible bone
A bad taste in your mouth or bad breath
An area that looks dry rather than covered by a clot
One thing worth knowing: dry socket doesn't usually come with a high fever or pus. Those point more towards an infection, which is a different problem. If you're not sure which one you have, that's a fair reason to ring your dentist and let them take a look.
When does dry socket happen?
Timing is one of the clearest clues. Dry socket typically shows up about 2 to 4 days after the extraction.
This is often the frustrating part. By day two or three, the first ache from the surgery is usually starting to ease, so you're expecting to feel better, not worse. When the pain climbs again instead of settling, that change is the signal to pay attention to.
What causes dry socket?
A few things make dry socket more likely, and some of them are within your control.
Smoking or vaping is a big one. The suction action of drawing on a cigarette or vape can pull the clot loose, and the chemicals don't help the area heal. Sucking through a straw works the same way, as does spitting or rinsing vigorously in the first day or two.
Other risk factors include poor oral hygiene around the site and a more difficult or surgical extraction, which is part of why lower wisdom teeth are more prone to it. There's also some evidence that the oral contraceptive pill raises the risk slightly. Knowing these causes makes the prevention steps below easier to follow.
How to prevent dry socket
You can't remove the risk entirely, but a few simple habits make a real difference. The single most useful thing is to follow the instructions your dentist gives you. Our post-operative instructions for wisdom tooth removal cover this in detail.
The main points:
Avoid smoking and vaping for several days, since the suction can dislodge the clot
Skip straws for the same reason
Don't rinse hard or spit for the first 24 hours
From day two, do gentle warm salt-water rinses if your dentist advises it
Keep the area clean, but gently
Stick to soft foods while things settle
None of this is complicated. It's mostly about being a bit gentler with your mouth than usual for the first few days.
Dry socket treatment
Dry socket needs a dentist to treat it properly, and the good part is that the treatment usually settles the symptoms quickly. It isn't something you can fix at home, but it isn't something to lose sleep over either.
At the appointment, your dentist gently cleans (irrigates) the socket to clear out any debris. They then usually place a medicated dressing, a soothing paste or pack that calms the exposed nerves and relieves the pain, often within a short time. Sometimes the dressing is replaced over a couple of visits while the area heals.
In the meantime, over-the-counter pain relief such as paracetamol or ibuprofen can help. Use it as directed on the packet, and check with your pharmacist that it suits you, especially if you take other medicines or have health conditions. Dry socket isn't strictly an infection, but it does need professional care. Once it's treated, it generally settles within days and doesn't tend to cause any long-term problems.
When to see your dentist
The classic sign is worsening pain 2 to 4 days after an extraction. If that's happening, it's worth getting in touch.
You should also see your dentist for severe pain, a bad taste that won't shift, or anything else that's worrying you. There's no need to wait it out and hope. If you think you have dry socket, our team can help through emergency dental care, and the sooner you're seen, the sooner the pain can be eased.

Frequently asked questions
What does dry socket feel like?
It usually feels like a sudden, sharp increase in pain a few days after your tooth comes out, often throbbing and stronger than the original soreness. The pain can spread to your ear, eye, temple or neck on the same side, even though the socket itself is the source. You might also notice a bad taste or bad breath, and the socket can look empty or dry rather than covered by a clot. A high fever or pus is less typical and points more towards an infection.
How long does dry socket last?
Left alone, dry socket can stay painful for several days to a week or so, which is uncomfortable and not something you need to put up with. Once your dentist treats it, things improve much faster. The cleaning and medicated dressing often ease the pain quickly, sometimes within a short time of the appointment. The dressing may be replaced over a couple of visits, but most people find the area settles within days of getting treatment.
How is dry socket treated?
Your dentist treats dry socket by gently cleaning (irrigating) the socket to clear any debris, then placing a medicated dressing. That dressing is a soothing paste or pack that calms the exposed nerves and relieves the pain, often fairly quickly. They may replace it over a few visits while the area heals. In the meantime, paracetamol or ibuprofen used as directed can take the edge off. It isn't strictly an infection, but it does need a dentist rather than a home remedy.
How can I prevent dry socket?
The biggest steps are avoiding smoking, vaping and straws for several days, since the suction can pull the protective clot loose. For the first 24 hours, don't rinse hard or spit. From day two, gentle warm salt-water rinses can help if your dentist recommends them. Keep the area clean but be gentle, stick to soft foods, and follow the post-op instructions you're given. None of it is difficult, it's mostly about treating your mouth a little more carefully than usual while it heals.
