A full mouth extraction – removing all teeth in one or both jaws – is a major step that understandably worries patients. Having all your teeth pulled is never a trivial decision. It must be medically justified, clearly explained, and followed by a reliable plan to replace the teeth (dentures or implants).
In this guide, we explain why a full mouth extraction may be necessary, the main medical reasons for removing all teeth, the risks and consequences (especially bone loss), and the modern treatment options: bone grafting, removable dentures, All-on-4 / All-on-6 bridges and basal implantology.
Can you really remove all your teeth?
Yes. From a surgical point of view, it is possible to remove all teeth from one or both arches, either in a single visit or over several appointments, under local or general anaesthesia depending on the case.
In everyday practice, a full mouth extraction should remain a last resort, used only when there is no reasonable way to keep the teeth. Clinical studies on tooth extraction in adults consistently show that the two main reasons for tooth loss are deep decay and advanced gum disease (periodontitis). These same causes are also the leading reasons why patients end up needing all their teeth removed.
Medical reasons that can lead to full mouth extraction
Advanced gum disease (generalised periodontitis)
Generalised periodontitis gradually destroys the bone and soft tissues that support the teeth. When teeth become very loose, painful and difficult to keep clean, it can be more realistic to carry out a full mouth extraction and then rebuild with dentures or implants, rather than trying to save a few remaining teeth with a very poor prognosis.

Multiple cavities and severely damaged teeth
Some patients present with multiple large cavities, cracked teeth and old failing restorations. This can make conservative dental treatment extremely complex or even impossible. When most teeth cannot be restored, removing all teeth and starting again on a clean, healthy base can be the safest option before fitting a full denture or implants.
General medical conditions, medications and diabetes
Certain general health problems (uncontrolled diabetes, severe immune disorders, previous head and neck radiotherapy, etc.) and some medications (bisphosphonates, cancer treatments, immunosuppressants) can weaken both teeth and jawbone. In extreme cases, keeping the teeth becomes too risky or too difficult. Multiple extractions – sometimes including full mouth extraction – may then be recommended to stabilise the situation and control infection.
Full mouth extraction before major surgery
In some situations, before major surgery with intubation or a long hospital stay, surgeons may ask the dentist to remove severely infected teeth (root remnants, chronic abscesses) to reduce the risk of serious infection during or after the operation.
This is not always a full mouth extraction, but if the mouth is badly broken down and many teeth are non-restorable, removing almost all or all teeth can be discussed.
Full mouth extraction and advanced periodontitis
In end-stage generalised periodontitis, several mechanisms act together:
- destruction of the alveolar bone and periodontal ligament
- teeth that move, drift and flare out
- everyday hygiene becoming very difficult, with plaque building up around loose teeth
As shown in the systematic review by Broers et al. (Journal of Dentistry, 2021), advanced periodontal disease, along with deep caries, is among the main causes of tooth extraction in adults, which explains why some cases of generalised periodontitis ultimately lead to full mouth extraction.
A vicious circle sets in: gum disease causes tooth mobility, and tooth mobility worsens gum disease. As shown in the work of Papapanou and colleagues (2018), advanced periodontitis is one of the main reasons for tooth loss and full mouth extraction in adults. When most teeth are affected, many clinicians prefer removing all teeth and planning a full implant-supported restoration, rather than trying to keep a few teeth with a very poor long-term outlook.
It is important to understand that pulling all your teeth does not magically “cure” gum disease. The bacteria and inflammatory tendency can persist in the gums and jawbone if no global periodontal treatment and follow-up are provided. Regular reviews and maintenance are still essential, even after full mouth extraction and dentures or implants.
What are the options after a full mouth extraction?
Once all teeth have been removed, several options are available to restore chewing function and a natural smile.
Complete removable dentures
A full removable denture is the simplest and often the least expensive solution. It can usually be fitted relatively soon after the initial healing period, or even immediately as an interim denture on the day of extraction.
Its main limitations are: sometimes poor stability, reduced chewing efficiency, less comfort, and more difficult adaptation in patients who have already lost a lot of bone.
Bone grafting and conventional dental implants
When the jawbone is very resorbed, bone grafting (using the patient’s own bone and/or bone substitutes) may be required to rebuild enough volume before placing standard implants. This method can provide excellent results, but it:
- requires several surgical procedures
- extends the overall treatment time
- carries additional risks (graft failure, infection, prolonged discomfort)
Full-arch bridges on implants: All-on-4 and All-on-6
All-on-4 and All-on-6 protocols use 4 or 6 implants per jaw to support a fixed full-arch bridge. This is a very popular solution that offers good stability and comfort when bone volume and quality are sufficient.
However, in cases of very advanced bone loss or significant risk factors (history of periodontitis, smoking, poor hygiene), these protocols become more challenging and may involve a higher risk of implant failure or complications. The treatment plan must always be tailored to the individual after clinical examination and 3D imaging.
Basal implantology: an immediate option after removing all teeth
In cases of severe bone resorption – for example after long-standing periodontitis or many years without teeth – basal implantology is often the most suitable option. Basal implants are anchored in the deep cortical bone, which is denser and much less affected by resorption than the superficial alveolar bone.
This approach often makes it possible to:
- avoid or greatly reduce bone grafting
- place the implants immediately after full mouth extraction
- plan a rapid loading protocol with a fixed bridge
The choice between removable dentures, All-on-4 / All-on-6, bone grafting or basal implantology is always made after a full evaluation: CT scan, clinical examination, medical history and, of course, the patient’s expectations.
Consequences of full mouth extraction: bone loss
After full mouth extraction, the alveolar bone gradually shrinks. Bone resorption is particularly marked in the first few months, then continues more slowly over the years. This bone loss leads to:
- a reduction in the height and thickness of the jaw ridge
- increasing difficulty stabilising removable dentures
- a more “collapsed” facial appearance over time if no treatment is undertaken

Gum and bone remodelling after full mouth extraction
After all teeth are removed, both the gum tissue and the underlying bone remodel. In general, the better a tooth was anchored (long roots, high and dense bone), the more marked the subsequent resorption can be. Very loose teeth with little supporting bone often lead to a less dramatic change, even though resorption still occurs.
As demonstrated in the scientific review by Tan et al. (International Journal of Dentistry, 2012), the alveolar ridge systematically undergoes significant resorption after tooth extraction.
This gum and bone remodelling is partly managed at the time of surgery by performing a gingival and bone reshaping procedure (gingivoplasty / alveoloplasty). The surgeon smooths and levels the ridges to create a regular contour, which improves comfort and provides a better base for dentures or implants. However, the exact amount and speed of resorption cannot be predicted precisely, as they depend on many individual factors (bone quality, gum thickness, age, smoking, general health, etc.).
Risks and complications after a full mouth extraction
Like any surgery, a full mouth extraction carries risks. The main ones are:
- pain and swelling in the first few days, usually controlled with prescribed painkillers
- moderate bleeding that should gradually decrease
- postoperative infections or dry sockets, more likely when many extraction sites are present or when risk factors such as smoking or uncontrolled diabetes are present
- delayed healing, especially in patients with general medical problems or heavy treatments
- Risk of gum (gingival) resorption, which can be managed with gingivoplasty
Clinical studies show that serious infectious complications are relatively rare but real, which is why a strict disinfection protocol and appropriate post-operative follow-up are essential.
Essential care after a full mouth extraction
Local hygiene and disinfection
- biting on gauze packs in the first hours to control bleeding
- using an antiseptic mouthwash (such as chlorhexidine), usually from the day after surgery, as prescribed by the surgeon
- avoiding smoking, alcohol and very hot or irritating foods during the first days
Antibiotics: not systematic
Antibiotics are not automatically prescribed after tooth extraction. They depend on the medical background (systemic disease, immune status, poorly controlled diabetes, risk of endocarditis, etc.) and on the complexity of the surgery.
For simple extractions in otherwise healthy patients, scientific data show that routine antibiotics do not always provide a clear benefit, while contributing to antibiotic resistance. The decision is therefore made by the surgeon on a case-by-case basis.
Follow-up and monitoring of extraction sites
Follow-up visits are scheduled to check healing, remove stitches if necessary, adjust temporary dentures and plan the definitive rehabilitation (full dentures, All-on-4 / All-on-6, basal implants, etc.).
Immediate dental implants after full mouth extraction
In many cases, it is possible to place dental implants immediately after a full mouth extraction, but only after a thorough assessment (CT scan, bone quality, gum disease, diabetes, smoking and other risk factors).
With conventional implants placed in the alveolar ridge, immediate full-arch implantation is mainly reserved for carefully selected cases with adequate bone volume and sometimes requires bone grafts or complex All-on-4 / All-on-6 protocols. These situations remain more sensitive to peri-implantitis, especially in patients with a history of periodontal disease.
Basal implants, by contrast, were specifically developed for patients with severe bone loss, often after generalised periodontitis. Basal implant systems anchor in the deeper, denser basal bone that is less affected by resorption. This often allows implants to be placed immediately after full mouth extraction and a fixed bridge to be fitted within a few days. Large clinical series on polished-surface basal implants report very few – and often no – documented cases of peri-implantitis when the protocol is correctly followed. This makes basal implantology one of the most consistent solutions for immediate full-arch rehabilitation in high-risk periodontal patients.
FAQ about full mouth extraction
It is a major procedure, but it can be safely done in a single visit in a well-selected patient, after a complete medical and dental assessment. The risks (bleeding, infection, fatigue) are higher than for a single extraction, which is why choosing the right type of anaesthesia and carefully following post-operative instructions is so important.
When almost all teeth are loose, painful and surrounded by infection, keeping them often means repeated treatment with poor long-term stability. A full mouth extraction removes the main infection sites and allows the dentist to rebuild on a stable base with dentures or implants.
Soft tissues (gums) usually heal visibly in 2–3 weeks, but bone remodelling continues for several months. Studies show significant dimensional changes in the jaw ridge during the first year. This is why some treatments (bone grafts, conventional implants) are delayed, while others, such as basal implantology, can be performed immediately or very soon after extraction.
Alternatives include fixed full-arch bridges on implants (All-on-4, All-on-6) and basal implant solutions. They can provide fixed teeth again but require a detailed work-up and a treatment plan tailored to your bone situation and general health.
In many cases, yes – even when bone is severely resorbed – because basal implants use deeper cortical bone. As with any treatment, a 3D scan and a specialist opinion are essential to confirm the indication.
Which warning signs after full mouth extraction should make me see the dentist urgently?
Increasing pain instead of improvement, fever, significant swelling, foul odour or taste, or pus discharge from the extraction sites should all prompt you to contact your surgeon or an emergency dental service quickly.
Does full mouth extraction completely get rid of gum disease?
When all teeth are removed, the diseased tissues around them are removed as well, so there is no longer “active periodontitis” around teeth in the strict sense. However, the same bacteria, general risk factors and inflammatory profile remain. A patient who lost teeth because of gum disease keeps:
a tendency towards inflammation of gums and oral mucosa
a higher risk of problems around conventional dental implants
the same need for strict oral hygiene and regular professional maintenance
In other words, full mouth extraction removes the damaged periodontal tissues around the teeth, but it does not erase periodontal susceptibility or the need for long-term monitoring.
In summary
Full mouth extraction is a major medical decision, usually reserved for situations where teeth can no longer reasonably be saved, such as advanced generalised periodontitis or multiple severe cavities. This complete tooth removal must always be combined with a carefully planned prosthetic or implant rehabilitation and close follow-up to minimise the risks of infection, bone loss and long-term discomfort – and to give the patient a stable, functional new smile.
