Yes, a dentist can usually remove an infected tooth. In fact, extracting a tooth that cannot be saved is one of the main ways of treating a dental infection because it removes the source of the problem and allows any associated pus to drain.
It is a common myth that an infected or abscessed tooth must always be treated with antibiotics before it can be extracted. In most otherwise well patients, a localised dental infection is not a reason to delay extraction. Depending on the tooth, another option may be root canal treatment, which removes the infection from inside the tooth while allowing the natural tooth to remain.
What Does an “Infected Tooth” Actually Mean?
A tooth infection usually begins when bacteria reach the dental pulp—the soft tissue containing nerves and blood vessels inside the tooth. This can happen because of deep tooth decay, a crack or fracture, previous dental treatment or trauma.
Once the pulp becomes infected or dies, infection can extend through the root canals and into the tissues around the tip of the root. A collection of pus may then develop, producing a dental abscess.
Possible symptoms include:
- Persistent or severe toothache
- Pain when biting or chewing
- Swelling of the gum, face or jaw
- A bad taste in the mouth or discharge of pus
- Difficulty opening the mouth
- Sensitivity to hot or cold
- Swollen lymph nodes
- Fever or feeling generally unwell in more significant infections
A dental abscess will not normally resolve permanently without dental treatment, so patients with suspected infection should arrange an urgent dental assessment.
Can a Dentist Pull an Abscessed Tooth?
Yes. If an infected tooth cannot reasonably be restored, extraction can remove the source of infection and allow drainage from the area.
Current dental guidance emphasises local treatment and source control. Depending on the situation, this may mean:
- Removing the infected tooth
- Draining an abscess
- Opening and treating the tooth through root canal treatment
Giving antibiotics while leaving the source untreated is generally not an effective long-term solution.
Do You Need Antibiotics Before an Infected Tooth Can Be Removed?
Usually not. Most localised dental abscesses in otherwise well patients do not require antibiotics simply because infection is present.
The priority is normally to drain the infection and treat its source. This is important because antibiotics have difficulty eliminating infection from dead tissue inside a tooth when the underlying dental problem remains.
Antibiotics may be appropriate when there are signs that infection is spreading or affecting the patient’s general health, such as:
- Spreading facial swelling or cellulitis
- Fever or significant malaise
- Swollen lymph nodes together with spreading infection
- Severe swelling where effective drainage cannot initially be achieved
- A particularly high risk of complications because of the patient’s medical condition
Even when antibiotics are required, they are normally an addition to definitive dental treatment rather than a replacement for it.
Why Do People Think You Cannot Extract an Infected Tooth?
One reason for this longstanding belief is that local anaesthetic can sometimes be more difficult to achieve in acutely inflamed tissue.
Local anaesthetic works less predictably when injected directly into highly acidic infected tissue. This does not mean the whole tooth is impossible to numb, however.
Dentists can often use alternative techniques, including placing anaesthetic away from the infected area or using a regional nerve block. Additional anaesthetic techniques can also be used where necessary.
Research comparing extraction of acutely infected teeth with non-infected teeth has not supported the idea that acute infection alone should routinely prevent extraction.
Can Removing an Infected Tooth Spread the Infection?
This is another common concern. For most localised dental infections, removing the source is part of controlling the infection rather than causing it to spread.
The dentist first assesses how extensive the infection is, whether the patient is systemically well and whether treatment can safely be provided in a dental practice.
If infection has spread into deeper facial or neck spaces, the situation becomes different. These infections may require urgent hospital or oral and maxillofacial treatment rather than a routine dental extraction.
When Might an Infected Tooth Not Be Removed Immediately?
There are situations where a routine extraction in general dental practice may not be the appropriate immediate treatment. Importantly, this is usually because of the severity or location of the infection, medical considerations or complexity of the extraction rather than simply because the tooth is infected.
Severe Spreading Infection
Significant facial or neck swelling, floor-of-mouth swelling, difficulty swallowing or breathing, severe restriction in mouth opening or signs of sepsis can indicate a serious spreading dental infection.
These patients may require urgent hospital assessment, airway management, surgical drainage and intravenous antibiotics. Removal of the dental source may still form part of treatment, but it may need to take place in a hospital or specialist setting.
Difficulty Accessing the Tooth
A severely restricted mouth opening, extensive swelling or a particularly difficult tooth position may make an immediate routine extraction impractical.
The dentist may arrange specialist management or other measures to achieve drainage and control the infection.
Complex Surgical Extraction
Some teeth require surgical rather than simple extraction—for example, a tooth that has fractured below the gumline or is difficult to access.
Read more about simple, surgical and wisdom tooth extractions.
Medical Factors
Your dentist will also review your medical history, medicines, allergies and other relevant risk factors before extraction.
Certain medical conditions or medicines may require additional planning, but they do not necessarily mean an infected tooth cannot be treated.
Is Root Canal Treatment Better Than Extracting an Infected Tooth?
Not every infected tooth needs to be removed. If enough healthy tooth structure remains and the tooth has a reasonable long-term prognosis, root canal treatment may allow it to be saved.
During root canal treatment, the infected or necrotic pulp is removed, the root canal system is cleaned and disinfected, and the canals are filled and sealed.
Extraction may be more appropriate when a tooth:
- Cannot be predictably restored
- Has a severe crack or fracture
- Has extensive decay extending too far below the gumline
- Has very poor periodontal support
- Has an unfavourable long-term prognosis despite further treatment
A dental examination and appropriate X-rays allow the dentist to compare the benefits and limitations of saving the tooth with removing it.
Can Antibiotics Cure a Tooth Abscess Without Dental Treatment?
No. Antibiotics alone do not normally cure the underlying cause of a dental abscess.
Symptoms may temporarily improve when antibiotics are required for spreading infection, but unless the source is treated, the infection can persist or return.
Repeated courses of antibiotics without appropriate dental treatment are therefore discouraged. They expose patients to medication side effects and contribute to antimicrobial resistance without reliably eliminating the dental source.
Should You Wait for Swelling to Go Down Before Extraction?
Not automatically. The old advice to always “wait for the infection to settle” is no longer considered appropriate for every case.
If the infection is localised, the tooth can be adequately anaesthetised and extraction is otherwise appropriate, removing the source promptly may be the best treatment.
If there is severe spreading swelling, significant trismus, systemic illness or another complication, the dentist may instead arrange urgent specialist or hospital management.
There is therefore no universal rule that you must finish a course of antibiotics before an infected tooth can be removed.
What Happens During Extraction of an Infected Tooth?
The dentist will first examine the tooth and usually take an X-ray where clinically indicated to assess its roots, surrounding bone and the extent of disease.
Local anaesthetic is then used to numb the area. You may feel pressure and movement during extraction, but you should not experience sharp pain.
If the tooth can be removed straightforwardly, it may be loosened and extracted through the socket. More complex teeth may require a surgical extraction, which can involve accessing the tooth through the gum or dividing it into sections.
Glow Dental’s private extraction fees currently start from £195 for a simple extraction and £300 for a surgical extraction. You can find more information in our guide to tooth extraction costs in the UK or view our current dental fees.
What Happens to the Infection After the Tooth Is Removed?
Removing the infected tooth eliminates the main dental source and the extraction socket can allow infected material to drain.
The body’s immune system can then resolve the remaining local inflammation as the socket begins healing.
Antibiotics are not automatically required after every extraction of an infected tooth. The dentist decides whether they are necessary based on signs of spreading or systemic infection and the patient’s individual risk.
Can an Abscess Come Back After Extraction?
Once the responsible tooth has been completely removed and the infection has adequately drained, recurrence from that tooth is unlikely.
However, continuing or increasing swelling, fever, worsening pain, persistent discharge or feeling increasingly unwell after treatment requires reassessment.
If symptoms are worsening rather than gradually improving, contact your dentist rather than simply starting leftover antibiotics yourself.
What Happens If an Infected Tooth Is Left Untreated?
A dental abscess does not normally disappear permanently without treatment. Symptoms can sometimes fluctuate or temporarily improve if pus drains, but the underlying source can remain.
Untreated infection can lead to:
- Repeated episodes of pain and swelling
- Loss of bone around the affected tooth
- Increasing difficulty restoring the tooth
- Spread into surrounding soft tissues
- Cellulitis
- In rare severe cases, deep neck-space infection or sepsis
Early emergency dental treatment can often prevent a local problem from becoming more complicated.
Can a Dental Abscess Burst on Its Own?
Sometimes an abscess can drain spontaneously into the mouth, which may produce a sudden bad taste and temporary reduction in pressure or pain.
This does not mean that the infection has been cured. The infected tooth or periodontal source can remain and the abscess may return.
Do not attempt to puncture or squeeze a dental abscess yourself. Arrange professional dental treatment instead.
When Is a Dental Infection an Emergency?
A suspected dental abscess needs urgent assessment by a dentist. Contact an emergency dentist if you have significant toothache, swelling or symptoms suggesting infection.
Call 999 or attend A&E immediately if you develop symptoms suggesting that swelling could be threatening deeper structures or the airway, including:
- Difficulty breathing
- Difficulty speaking or swallowing
- A large amount of swelling inside the mouth
- Severe difficulty opening the mouth
- Swelling or pain around the eye
- New problems with your vision associated with facial swelling
These symptoms can indicate a more serious infection requiring hospital assessment rather than routine dental care.
Can a Nervous Patient Have an Infected Tooth Removed?
Yes. Dental anxiety does not mean an infected tooth has to remain untreated.
Tell your dentist if you are particularly anxious about extraction. Treatment can be explained gradually, local anaesthetic can be carefully administered and additional anxiety-management options may be considered.
Glow Dental provides support and sedation options for appropriate nervous dental patients.
What Happens After an Infected Tooth Is Extracted?
The extraction socket normally heals gradually over the following weeks. Follow the post-operative instructions provided by your dentist and avoid disturbing the blood clot that forms in the socket.
Depending on which tooth has been removed, it may or may not need replacing.
If replacement is recommended, possible options can include a dental implant, a dental bridge or a partial denture.
Your dentist can discuss these options once the infection has been treated and the long-term needs of the area are clear.
Frequently Asked Questions About Extracting an Infected Tooth
Can a dentist pull an infected tooth on the same day?
Often, yes. If extraction is clinically appropriate, the infection is manageable in primary dental care and adequate local anaesthesia can be achieved, an infected tooth can often be extracted without first waiting several days for antibiotics.
Do I need antibiotics before extraction?
Not routinely. Antibiotics are primarily used when infection is spreading, causing systemic symptoms, cannot initially be adequately drained or presents a particularly high risk of complications.
How long after antibiotics can a tooth be removed?
There is no standard waiting period. If antibiotics are required, the timing of definitive treatment is determined by the clinical situation. Treatment of the dental source should not be unnecessarily postponed simply to finish an antibiotic course.
Will local anaesthetic work on an infected tooth?
Usually, although anaesthesia can sometimes be more difficult when significant inflammation is present. Dentists can use techniques such as regional nerve blocks and additional anaesthetic approaches rather than relying solely on an injection directly into infected tissue.
Is extraction or root canal better for an infected tooth?
If the tooth can be predictably saved, root canal treatment may preserve the natural tooth. If the tooth is severely damaged, fractured or has a poor prognosis, extraction may be more appropriate. The best option depends on the individual tooth rather than infection alone.
Can antibiotics stop tooth pain?
Antibiotics are not painkillers and are not routinely indicated for toothache without spreading or systemic infection. Dental pain usually requires diagnosis and treatment of its underlying cause.
Can I go to my GP for a dental abscess?
A dental abscess requires dental treatment, so you should normally contact a dentist or NHS 111 if urgent dental care is unavailable. A GP cannot perform the dental procedure needed to remove the source of infection.

Summary: Can a Dentist Remove an Infected Tooth?
Yes. In most cases, an infected or abscessed tooth can be removed safely, and active infection alone is not normally a reason to postpone extraction.
The priority in a dental infection is to control the source through extraction, root canal treatment or appropriate drainage. Antibiotics are generally reserved for spreading infection, systemic symptoms, severe swelling where drainage cannot initially be achieved or patients at increased risk of complications.
Severe facial or neck swelling, difficulty breathing or swallowing, significant restriction in opening the mouth, or swelling around the eye require urgent assessment because these can indicate a more serious spreading infection.
