After an Extraction

Dry socket: pain that gets worse a few days after an extraction

Why pain that should be easing sometimes goes the other way

After an extraction, pain is expected to be at its worst in the first day or two and then gradually ease. For some people the opposite happens: on the second or third day the pain gets worse again, spreads to the ear and temple, and leaves a bad taste in the mouth. This is called dry socket (alveolar osteitis), and it is not an infection. On this page we explain how it is recognised, how it differs from an abscess, what your dentist will do and why you should not poke at the socket at home.

Short answer

Dry socket happens when the blood clot covering the extraction socket comes away too early or does not form properly; the bone and nerve endings underneath are exposed, and this causes severe pain, often without any infection. The sign is pain that, contrary to what you would expect, gets worse two or three days after the extraction and spreads to the ear and temple, with a bad taste in the mouth. A high temperature and swelling are usually absent; if present, they suggest a different picture, such as an abscess. Do not poke at the socket at home; call your dentist. Treatment is a simple procedure at the dentist that takes a few minutes.

When it usually starts: 2–3 days after the extraction
Where it is most common: Lower molar and wisdom tooth extractions
High temperature, swelling, pus: Usually none; if present, an abscess is suspected
Treatment: A few minutes of cleaning and a dressing at the dentist

What happens in your mouth with dry socket

As we explain on our page about what to do after a tooth extraction, a blood clot fills the socket after an extraction; this clot both stops the bleeding and covers the bone and nerve endings underneath. Dry socket starts when this clot comes away earlier than expected or does not form properly. As the NHS describes it, dry socket is a painful condition in which the blood clot in the extraction socket does not form properly or comes out before the gum has healed.

When the clot comes away, what is left behind is not an empty socket but exposed bone and nerve endings. Air in the mouth, hot or cold drinks and food debris come into direct contact with this surface, and this creates a throbbing pain that does not go away with rest. As Cochrane points out, dry socket is not caused by bacteria; in other words, it is not an infection but a wound created by the loss of the clot itself.

Timing is one of the most reliable ways to recognise dry socket. According to the Oral Health Foundation, discomfort after an extraction is usually short-lived and goes away with ordinary painkillers; but in some people, if the clot in the socket has not formed properly, the pain comes back three or four days after the extraction. This is a different pattern from the normal course of the first few days: pain that should be easing gets worse instead.

It is easy to confuse dry socket with an abscess (infection), because both cause pain a few days after an extraction. The difference is this: dry socket does not cause a high temperature, and it does not produce noticeable swelling or pus around the socket. Even if the pain spreads to your ear and temple, if you have swelling in your cheek, difficulty swallowing, or a high temperature with shivering, this suggests a different picture, such as an abscess; we cover this separately on our page about gum swelling and abscesses.

We have clear information about who gets dry socket more often, but it is not possible to say in advance who will definitely get it. The Cochrane review shows that dry socket is more common in people with poor oral hygiene and after lower wisdom tooth extractions, and that smoking also increases the risk. We list these factors one by one in the next section.

There is no sure way to prevent dry socket completely, but there is one method that may help reduce the risk: the Cochrane review shows that using a chlorhexidine mouthwash before the extraction or starting 24 hours after it, or the dentist placing chlorhexidine gel in the socket, can reduce how often dry socket occurs. This is something your dentist recommends and prescribes; do not buy chlorhexidine at the pharmacy and start using it on your own.

Although dry socket is unpleasant and painful, it is not dangerous and does not cause lasting damage. When your dentist cleans the socket and places a soothing dressing, the pain usually eases noticeably within hours. The real risk is putting off going to the dentist and trying to get by with home remedies.

Who gets it more often, and who gets it less often

Dry socket does not happen after every extraction, and it is not possible to say for certain in advance who will get it. The lists below are based on the factors noted by the NHS and Cochrane; seeing yourself in the second list does not mean you will get dry socket, only that the chances are a little higher and you need to follow the rules for the first few days more strictly.

The tooth can be saved

If it is a simple extraction of a single-rooted toothAfter a tooth with a straight root that comes out without an incision, the clot forms more steadily and stays in place.
If you do not smokeThe NHS states that smoking has a negative effect on healing and on the risk of infection; the suction of drawing on smoke also puts strain on the clot.
If you keep up good oral careAccording to the Cochrane review, dry socket is less common in people with good oral hygiene. Regular brushing and flossing reduce the load of bacteria and food debris around the socket.
If the extraction is in the upper jaw or at the frontAccording to the NHS, dry socket is most common after lower wisdom tooth extractions; it is rarer after extractions in the upper jaw and at the front of the mouth.

Saving it is unlikely to hold

If it is a lower molar or wisdom tooth extractionThe NHS states that dry socket is most common after these extractions; the bone is denser and the surface the clot has to hold on to is narrower.
If you smoke cigarettes or shishaThe suction of drawing on smoke can dislodge the clot, and nicotine reduces blood flow to the area.
If you have had dry socket beforeSomeone who has had it once is a little more likely to get it again; tell your dentist before the extraction.
If the extraction was difficult or took a long timeIn extractions where bone is removed or the tooth is taken out in sections, the socket is bigger and it is harder for the clot to hold on. If your dentist expects a difficult extraction, they will ask you to pay particular attention to the aftercare instructions.

What happens at the dentist

Dry socket is treated at the dentist, not at home, and a single appointment usually reduces the pain noticeably. The steps below are what to expect at that appointment.

1
Examination and ruling out an abscess
Your dentist looks at the socket, checks whether there is a high temperature or swelling, and tells the condition apart from an abscess. Dry socket is usually diagnosed just by looking; additional imaging is generally not needed.
2
Rinsing out the socket
Food debris and loose tissue in the socket are cleaned away by gently rinsing it with warm saline or salt water. This both reduces the pain and helps the dressing that follows to work.
3
A soothing dressing
According to the Cochrane review, a soothing, medicated dressing placed in the socket noticeably reduces pain. If needed, the dressing can be changed a few times over a few days.
4
Pain control
Your dentist recommends a suitable painkiller for you or reviews what you are currently taking. After the dressing, the pain usually eases noticeably within hours.
5
Antibiotics, only if needed
Because dry socket is not caused by bacteria, antibiotics are usually not needed. If there is a high temperature, spreading swelling or a condition that affects the immune system, your dentist will assess this separately.

Dry socket or abscess? The signs that tell them apart

The two get confused because both can cause pain a few days after an extraction. The two pictures below help you see which one your situation looks more like; your dentist makes the definite diagnosis.

Signs that suggest dry socket

The pain spreads to the ear and temple, the socket looks empty or greyish, and there is a bad taste in the mouth, but a high temperature, noticeable swelling or pus are usually absent. According to the NHS and Cochrane, dry socket is not caused by bacteria. The pain usually gets worse with hot or cold, and sometimes even when air passes over the gap.

Signs that suggest an abscess (infection)

There is noticeable swelling in the cheek or gum, pain that gets worse when touched, a high temperature, shivering, or pus that leaves a taste in the mouth. We cover this in detail on our page about gum swelling and abscesses; if you have difficulty swallowing or shortness of breath, go to A&E. A temperature that is high, or keeps rising, is another sign that points towards infection.

Mistakes made at home that make it worse

Dry socket is painful, but it does not get better with home remedies; the following are common mistakes that delay recovery rather than helping it.

Poking at the socket with your tongue or finger

Touching the exposed bone increases the pain and can carry bacteria to the area. Even if your tongue keeps drifting there without you meaning it to, make a conscious effort to stop it.

Trying to clean it with a toothpick or toothbrush

Cleaning inside the socket yourself irritates the tissue even more. Cleaning it is your dentist's job; you just brush your other teeth as normal.

Carrying on smoking

Continuing to smoke after the pain has started delays healing and can make the existing pain worse.

Trying to get by on painkillers for days

Painkillers give temporary relief but do not remove the cause. If the pain is getting worse after the second or third day, call your dentist instead of taking more medicine.

Applying heat to the outside of your cheek

Heat increases blood flow to the area and can make the pain, and any swelling, worse. A cold compress on the outside is a safer option.

What to expect after treatment

The sequence below describes what happens after your dentist has cleaned the socket and put in a dressing.

The same day
After the dressing, the pain usually eases noticeably within a few hours. Keep taking the painkiller your dentist recommends.
The first few days
If needed, the dressing is changed a few times. Stop smoking, do not poke at the socket, and brush your other teeth as normal.
Within a week
The pain largely subsides and the socket starts to get smaller. If the pain gets worse again during this time, let your dentist know.
Within a few weeks
The socket becomes covered with soft tissue. The question of what will replace the extracted tooth may come up during this period; we explain what can be done while you wait on our page about temporary options for a missing tooth.

Message us right away if

Pain continues even after the dressing. A dressing usually brings noticeable relief within hours. If that relief does not last, go back to your dentist.
You have a high temperature, shivering or pus. These are signs of infection rather than dry socket; you need to be seen the same day.
Swelling is growing, or swallowing or breathing is getting harder. This is an emergency; do not wait for an appointment, go to A&E or call 112.
Bleeding has started again. Dry socket itself does not cause bleeding; new bleeding may point to a different problem. We cover this separately on our page about bleeding after a tooth extraction.

What makes it last longer

This page is not selling a treatment; it explains dry socket. Even so, it helps to know the factors that decide how long the process will take:

How soon you see a dentist: Early cleaning and a dressing reduce the pain more quickly; if you put off seeking help, the discomfort lasts longer.
How difficult the extraction was, and where: In lower jaw extractions done through an incision, the socket is bigger, so healing may take a little longer.
Whether you stop smoking: Continuing to smoke during treatment can reduce the effect of the dressing and drag the process out.
What will replace the extracted tooth: Discussing how the gap will be filled once the dry socket has healed, while the changes in the bone are still at an early stage, leaves you with a wider range of options.

Frequently asked questions

How many days does dry socket last?

After your dentist cleans the socket and puts in a dressing, the pain usually eases noticeably within a few hours, and if needed the dressing is repeated a few times over a few days. If it is left untreated, the discomfort can last up to a week; that is why seeking help early shortens the time it lasts.

Does dry socket go away on its own?

It does go away in time, but waiting is not necessary and only means you are in pain for no reason. A simple cleaning and dressing by your dentist reduces the pain noticeably within hours; that is why it is best to book an appointment rather than wait.

Does dry socket give you a high temperature?

Usually not. As Cochrane points out, dry socket is not caused by bacteria; if there is a high temperature, shivering or spreading swelling, this suggests an infection such as an abscess, and you need to be assessed separately.

Why does dry socket pain spread to the ear and temple?

The exposed nerve endings in the extraction socket are part of the network of nerves in the jaw area; the pain can spread through this network to the ear and temple. This is one of the most typical signs of dry socket.

How can I tell at home if I have dry socket?

Pain that should be easing two or three days after the extraction getting worse again, spreading to the ear or temple, and leaving a bad taste in the mouth suggests dry socket. Rather than trying to look at the socket with a mirror or your phone torch, call your dentist; they will make the definite diagnosis.

Is dry socket an infection?

No. The NHS and Cochrane describe dry socket as a condition separate from infection; dry socket is a wound created by the loss of the clot itself. If you have a high temperature, noticeable swelling or pus, this suggests a different picture: an abscess.

Can I treat dry socket at home?

No. Painkillers can give temporary relief, but cleaning the socket and covering it with a soothing dressing is done at the dentist. Things people try at home, such as poking at it or cleaning it with a toothpick, do not make it better and can make it worse.

What should replace the tooth once the dry socket has healed?

Once the dry socket has healed, you can discuss filling the gap with an implant, bridge or denture with your dentist. We explain temporary options for the waiting period on our page about temporary options for a missing tooth, and how long to wait for an implant on our page about how long to wait for an implant after an extraction.

Is it possible to prevent dry socket?

There is no sure way to prevent it, but some habits reduce the risk: stopping smoking, looking after your oral hygiene and following the aftercare instructions your dentist gives you are the main ones. According to the Cochrane review, using a chlorhexidine mouthwash recommended by your dentist before and after the extraction can also reduce the risk. We cover the rules for these first few days in detail on our page about what to do after a tooth extraction.

Should I go to A&E or to a dentist for dry socket?

Dry socket itself is a dental problem, not a hospital emergency; call your own dentist where you are, or an out-of-hours dental clinic. If it comes with symptoms such as a high temperature, swelling that is growing quickly, difficulty swallowing or shortness of breath, go to a hospital A&E department; these symptoms suggest a spreading infection rather than dry socket.
