All-on-4 Dental Implants: A Complete Guide to Treatment, Recovery and Costs
All-on-4 Dental Implant
All-on-4 Dental Implant
All-on-4 is a full-arch dental implant treatment that uses four implants to support a fixed set of replacement teeth.
If you’re considering the treatment, there is more to understand than how the implants are placed. Recovery, temporary and final teeth, maintenance, risks, costs and alternatives all deserve consideration before you decide.

All-on-4 and Bone Loss
Bone loss is common after teeth are lost, and it can affect where implants can be placed.
The angled implants used towards the back of an All-on-4 restoration can make good use of the bone that is available in some patients. That doesn’t mean bone grafting is never needed.
A CBCT scan can help your dentist look at:
- How much bone is available
- The position of the nerves
- The location of the sinuses
- Where implants can be safely placed
- Whether another procedure may be needed
If the available bone isn’t suitable, your dentist may discuss grafting, a different implant approach or another way of replacing the teeth.
The All-on-4 Treatment Journey
The exact process depends on your situation, but there are a few main stages to expect.
Consultation and assessment
Your dentist will look at your teeth, gums, bite and jawbone. Imaging such as a CBCT scan may also be used to plan the implants.
This is the time to discuss:
- Your treatment goals
- Any health conditions or medications
- Teeth that may be worth keeping
- Bone availability
- Alternative treatment options
- Expected costs and timeline
Implant placement
The four implants are placed according to the treatment plan. If some remaining teeth cannot be predictably maintained, they may be removed as part of the procedure.
Temporary teeth
Some patients receive temporary full-arch teeth while the implants heal.
They allow you to eat and speak during this period, but they are not necessarily made or designed in the same way as the final teeth.
Healing
The implants need time to integrate with the surrounding bone.
During this stage, your dentist will monitor your healing and may adjust the temporary teeth if needed. Your diet and cleaning routine may also need some changes.
Final teeth
Once healing has progressed sufficiently, the final prosthesis can be made and fitted.
Your dentist will check things such as:
- Fit and comfort
- Your bite
- Appearance
- Speech
- How easily the area can be cleaned
Temporary Teeth vs Final Teeth
The temporary teeth are there to get you through the healing period. They aren’t simply a cheaper version of your final teeth.
| Temporary teeth | Final teeth |
|---|---|
| Used while the implants heal | Designed for longer-term use |
| May be fitted soon after surgery | Fitted once healing is sufficiently advanced |
| Helps you eat and speak during recovery | Designed around your established bite and needs |
| May need adjustments along the way | Fine-tuned for fit, function and appearance |
| Made with the healing stage in mind | Material depends on the planned restoration |
Before treatment, ask what type of temporary teeth you’ll receive and what is planned for the final restoration. It makes the whole process much easier to understand.

What Can You Expect to Feel During Recovery?
What Can You Expect to Feel During Recovery?
The first few days are generally when swelling and discomfort are most noticeable.
You may also notice:
- Bruising around the face or gums
- Tenderness around the surgical areas
- A feeling of pressure from the temporary teeth
- Some difficulty opening your mouth comfortably
- Changes in how your teeth feel when you bite
- Speech feeling slightly different while you adjust
These symptoms should generally improve as healing progresses.
If pain, swelling or discomfort is getting worse rather than settling, or something about the restoration suddenly feels different, contact your dental team.
Eating With All-on-4
Eating With All-on-4
Eating will take a little getting used to, particularly in the early stages.
During early recovery
Choose foods that are soft and don’t require much chewing, such as:
- Smooth soups
- Yoghurt
- Scrambled eggs
- Soft pasta
- Mashed vegetables
- Smoothies, where appropriate
As healing progresses, you can gradually introduce firmer foods according to your dentist’s advice.
Even once you’re eating normally, very hard or sticky foods may need to be limited depending on your restoration and bite.
Getting Used to Your New Teeth
Getting Used to Your New Teeth
There can be an adjustment period after receiving All-on-4 teeth, particularly if you’ve been without teeth or have worn dentures for some time.
You may initially notice that:
- Your bite feels different
- Your tongue needs time to adjust
- Certain sounds feel unfamiliar
- Food feels different when you chew
- The prosthesis feels more noticeable than you expected
Most people become more accustomed to these changes with time. Your dentist can also make adjustments if the bite, fit or comfort isn’t quite right.
What Do All-on-4 Teeth Feel Like Once You’re Healed?
What Do All-on-4 Teeth Feel Like Once You’re Healed?
All-on-4 teeth are designed to function as a fixed replacement for a full arch, but they won’t feel exactly like natural teeth.
The implants themselves don’t have the same sensation as natural tooth roots because they don’t contain the same nerves. You may still feel pressure through the restoration when biting and chewing.
Food can also collect around and underneath a fixed prosthesis, which is why cleaning is such an important part of living with All-on-4.
If your teeth feel loose, your bite suddenly changes or the restoration becomes uncomfortable, that isn’t something to simply get used to. It should be checked.
All-on-4 Compared with Other Full-Arch Options
All-on-4 is one way to replace a full arch, but it isn’t the only one. The differences become clearer when you look at how each option is supported, maintained and used day to day.
| All-on-4 | All-on-6 | Implant-supported denture | Conventional denture | |
|---|---|---|---|---|
| Implants | Four | Six | Usually two or more | None |
| Teeth | Fixed | Fixed | Usually removable | Removable |
| Implant surgery | Yes | Yes | Yes | No |
| Stability | Implant-supported | Implant-supported | Greater retention than a conventional denture | Relies on gum and jaw support |
| Cleaning | Daily cleaning around prosthesis and implants | Daily cleaning around prosthesis and implants | Removed for cleaning | Removed for cleaning |
| Maintenance | Regular implant and prosthesis reviews | Regular implant and prosthesis reviews | Regular implant reviews and denture care | Regular denture reviews |
All-on-4 vs All-on-6
The main difference is the number of implants, but that doesn’t make All-on-6 automatically better.
Six implants may be recommended where the patient’s anatomy, bite or treatment plan makes additional implant support appropriate. In another case, four implants may provide suitable support.
The decision should be based on the individual assessment rather than simply choosing the option with more implants.
All-on-4 vs Implant-Supported Dentures
Both treatments use implants, but the prosthesis works differently.
An All-on-4 restoration is fixed to the implants. An implant-supported denture is generally removable, allowing the patient to take it out for cleaning.
An implant-supported denture may therefore be worth considering for someone who wants greater stability than a conventional denture but prefers a removable restoration.
All-on-4 vs Conventional Dentures
Conventional dentures don’t require surgery or dental implants, which can make them a simpler option for some patients.
They are removable, however, and their stability depends on the shape and condition of the gums and jaw.
All-on-4 involves more treatment, but provides a fixed implant-supported restoration.
There isn’t one option that is best for everyone. The right choice depends on your oral health, anatomy, preferences, treatment goals and what your dentist believes can be maintained predictably over time.
Potential Risks and Complications
Potential Risks and Complications
What Happens If an Implant Fails?
An implant can occasionally fail to integrate with the bone or develop problems after it has been functioning for some time.
This doesn’t necessarily mean the entire treatment has failed. The appropriate response depends on why the implant has failed, when the problem occurred and the condition of the surrounding tissues.
Your dentist may need to remove the affected implant, allow the area to heal and reassess the treatment before deciding on the next step.
This is one reason regular maintenance matters. Problems are generally easier to assess when they are identified early.
What Are All-on-4 Teeth Made From?
The material used for the final prosthesis can vary. The choice may affect the appearance, weight, durability, repairability and cost of the restoration.
Depending on the treatment plan, options may include:
- Acrylic or resin-based teeth
- Composite or hybrid restorations
- Zirconia-based restorations
- Other material combinations designed for full-arch implant prostheses
There isn’t one material that is automatically right for every patient.
Your dentist should explain what is being recommended, why it suits your situation and what its advantages and limitations are.
How Long Does All-on-4 Last?
The implants and the prosthesis have different considerations when it comes to longevity.
Implants can remain functional for many years when they are healthy and properly maintained. The prosthesis, however, is subject to normal wear and may eventually require repair, adjustment or replacement.
Long-term outcomes can be affected by:
- Oral hygiene
- Gum and implant health
- Smoking
- Bite forces and grinding
- General health
- The quality and design of the prosthesis
- Regular professional maintenance
There is no single lifespan that can be guaranteed for every patient.
Looking After Your All-on-4 Teeth
All-on-4 teeth are fixed, but they still need daily care. Keeping the gums and implants clean is important for protecting the tissues around them and helping the restoration stay in good condition.
What If the Prosthesis Needs to Be Removed?
What If the Prosthesis Needs to Be Removed?
“Fixed” doesn’t necessarily mean the prosthesis can never be removed.
Your dentist may need to remove it during professional maintenance, repair or if there is a problem that needs closer assessment.
This is different from a removable denture, which the patient can take out at home.
If your prosthesis is removed, your dentist will explain why and what needs to happen before it is replaced.

Frequently Asked Questions
Can All-on-4 be used if I still have some teeth?
It can be, depending on the condition of the remaining teeth. Your dentist will assess their long-term prognosis before deciding whether they should be retained or removed.
Are All-on-4 teeth fitted on the same day as the implants?
Some patients may receive temporary teeth shortly after implant placement. This depends on factors such as implant stability, bone quality and the treatment plan. The temporary restoration is not the same as the final prosthesis.
Can All-on-4 implants fail?
Yes. An implant may fail to integrate with the bone or develop problems later. If this happens, the cause needs to be assessed before deciding how to manage it.
Is All-on-4 better than All-on-6?
Not necessarily. The number of implants is only one consideration. Your bone, bite, anatomy and overall treatment plan will help determine which approach is appropriate.
How long does All-on-4 last?
There is no fixed lifespan that applies to every patient. The implants and prosthesis can have different lifespans, and factors such as oral hygiene, smoking, bite forces and regular maintenance can influence how long they remain functional.
Is All-on-4 permanent?
It is intended as a long-term treatment, but it is not maintenance-free. The prosthesis may eventually need adjustment, repair or replacement, even if the implants remain healthy.
Can smokers have All-on-4 implants?
Smoking can affect healing and increase the risk of implant complications. If you smoke, this should be discussed during your assessment so the risks can be considered as part of your treatment planning.
Is All-on-4 suitable for older patients?
Age alone does not determine suitability. General health, bone condition, oral health and the ability to maintain the implants and prosthesis are more important considerations.
