How many teeth do you get on All on 4 dental implants is one of the first questions people ask, and the answer surprises most people. You get a full arch of teeth: 10 to 14 teeth on the top or bottom jaw, supported by just 4 titanium implants. A complete set of upper and lower teeth uses only 8 implants total.
It’s a full mouth restoration, not just a few replacements. This guide covers exactly what you get, how it works, what it costs in Australia, and what real life looks like after the procedure.
What Exactly Do You Get With All on 4 Dental Implants?
You get a All on 4 dental implants. That’s a dental term for a complete set of replacement teeth attached permanently to your jaw. The prosthesis sits on 4 implants that fuse directly into your jawbone, just like natural tooth roots do.
Here’s what the full treatment includes:
- 4 titanium implants per jaw (placed into the bone)
- A custom-made arch of 10 to 14 artificial teeth
- A temporary set of teeth fitted on the same day as surgery
- A permanent prosthesis fitted after healing, usually 3 to 6 months later
The prosthesis looks and functions like natural teeth. You bite, chew, and speak with them just as you would with real teeth. They don’t come out at night. They don’t sit in a glass of water. They stay in your mouth.
Why Only 4 Implants for a Full Arch of Teeth?
Traditional implants need one post per tooth, so replacing 12 teeth meant 12 implants. All on 4 changed that by placing two implants straight into the jaw at the front and two at an angle of 30 to 45 degrees at the back. The angled back implants reach denser bone and spread the load across the full arch.
Research published in the International Journal of Oral and Maxillofacial Implants tracked All on 4 patients over 10 years and found implant survival rates above 94 percent [1]. That’s comparable to traditional full-arch implant methods that use far more implants and cost significantly more.
The angled placement also means most patients don’t need bone grafting, even if they’ve experienced some bone loss from missing teeth. That reduces both cost and recovery time.
How Long Does It Take to Get All on 4 Dental Implants?
The surgery itself takes roughly 2 to 4 hours per arch. You leave the clinic the same day with a full set of temporary teeth already attached. Most people call this the “teeth in a day” part of the process.
The full timeline looks like this:
- Consultation and scans, usually 1 to 2 appointments over 1 to 2 weeks
- Surgery day, implants placed and temporary teeth fitted, takes 2 to 4 hours
- Healing phase, 3 to 6 months for implants to fuse with bone (osseointegration)
- Permanent teeth fitted, your custom final prosthesis is attached once healing is confirmed
From your first consultation to your permanent teeth, expect around 4 to 8 months. The wait is for bone healing, not for the dental work itself. You have functional teeth throughout the entire process.
What Does All on 4 Cost in Australia?
All on 4 dental implants in Australia cost between $20,000 and $35,000 per arch depending on the clinic, location, materials used, and your specific jaw condition. A full mouth (top and bottom) runs from $40,000 to $65,000 AUD.
That sounds like a lot. But compare it to the alternative. Traditional implants replacing a full arch with individual posts can cost $50,000 to $80,000 per arch. Removable dentures cost far less upfront (around $1,500 to $4,000) but need replacing every 5 to 10 years and come with ongoing costs for adhesives, repairs, and relining.
Many clinics offer payment plans or financing options. Some private health funds cover a portion under major dental. It’s worth calling your fund directly to check your extras cover before you book a consultation.
Does Food Get Stuck Under All on 4 Dental Implants?
Yes, food can get under the bridge. This is one of the most common things patients ask about after treatment. The prosthesis sits slightly above the gum line, which creates a small gap. Food particles, particularly small seeds, rice, and fibrous foods, can collect there.
This is manageable with the right tools. A water flosser (oral irrigator) clears the gap quickly and effectively. Most dentists recommend using one daily as part of your All on 4 care routine. A soft-bristle toothbrush and floss threaders also help reach under the bridge.
You do need to be more deliberate about cleaning than you were with natural teeth. Patients who skip this step risk gum inflammation around the implants, a condition called peri-implantitis, which can threaten the implants over time.

What Is the Downside of All on 4 Dental Implants?
All on 4 works well for most people, but it has real drawbacks worth knowing before you commit.
- Cost. The upfront price is high. For many people it requires financing or planning ahead.
- Surgery and recovery. This is a surgical procedure. You’ll have swelling, soreness, and bruising for 1 to 2 weeks. Most people need a soft food diet for 6 to 12 weeks while the implants heal.
- Irreversible. Once implants fuse with the bone, removal is a significant surgical process. You’re committing to this restoration for life.
- Prosthesis can crack or chip. The bridge itself (especially acrylic versions) can fracture under heavy bite force. Zirconia prostheses are far more durable but cost more.
- Not suitable for everyone. Heavy smokers, people with uncontrolled diabetes, and those with severe bone loss in certain areas may not be good candidates without additional treatment first.
- Cleaning takes effort. Daily cleaning under the bridge is necessary. It takes a few minutes but needs to happen every day.
None of these downsides make All on 4 a bad choice. They make it an informed choice. Most patients who go through the process report it changed their quality of life significantly.
Is It Hard to Talk With All on 4 Dental Implants?
For the first 1 to 4 weeks, yes. Your mouth is adjusting to a new set of teeth and your tongue needs to relearn how to form sounds around them. This is normal and temporary.
Common speech changes in the early weeks include a slight lisp, muffled sounds, or the feeling that your words are different. These usually resolve on their own as your mouth adapts. Practicing by reading aloud, talking to friends, or singing along to music speeds up the adjustment.
By 4 to 8 weeks, most patients speak clearly and naturally. The teeth are fixed, so unlike removable dentures, there’s no slipping or clicking when you speak. Long term, All on 4 patients consistently report speech improvement compared to living with missing teeth or loose dentures.
All on 4 vs Removable Dentures, What Is Actually Different?
Dentures rest on the gum and rely on suction or adhesive to stay in place. All on 4 implants anchor directly into the jawbone. This changes everything about how the teeth feel and function.
- All on 4 bite force reaches up to 90 percent of natural teeth. Dentures sit at around 20 to 25 percent of natural bite force.
- All on 4 implants stimulate the jawbone the way natural roots do, which prevents bone loss. Dentures don’t stimulate bone and can accelerate jaw shrinkage over time.
- All on 4 doesn’t move, slip, or need adhesive. Dentures can shift, especially as the jaw changes shape over years.
- All on 4 has no impact on taste because nothing covers the palate. Full upper dentures cover the roof of the mouth, which reduces taste sensation.
Dentures are still a valid option for many people, particularly those who aren’t surgical candidates or who prefer a lower upfront cost. But they’re a different experience from fixed implants.
Who Is a Good Candidate for All on 4?
You’re likely a good candidate if: Some people with certain medical conditions may need additional evaluation before proceeding.
- You’re missing most or all of your teeth on one or both arches
- You have enough jawbone for at least 4 implants (your dentist checks this with a CT scan)
- You’re in reasonable general health
- You don’t smoke, or are willing to quit before and during healing
- You want a permanent, fixed solution rather than removable dentures
Your dentist will take a 3D cone beam CT scan of your jaw to measure bone density and map the safest implant positions. This scan is what makes the surgery precise and predictable.
How Do You Care for All on 4 Implants Long Term?
The implants themselves don’t decay, but the gum and bone around them can still develop problems if you skip cleaning. Here’s what good All on 4 care looks like:
- Brush twice daily with a soft toothbrush, cleaning along the gum line under the bridge
- Use a water flosser once a day to flush under the prosthesis
- See your dentist every 6 months for a professional clean and implant check
- Avoid biting hard items like ice, bones, or pen lids that can crack the prosthesis
- Tell your dentist immediately if you notice any looseness, soreness, or change in your bite
With proper care, the titanium implants can last a lifetime. The prosthesis on top may need replacement after 10 to 20 years depending on the material, your bite force, and how well you maintain it.
Frequently Asked Questions
How many teeth come with All on 4 implants?
You get 10 to 14 teeth per arch. Most people receive 12 teeth on the top and 12 on the bottom for a full set. The number depends on your jaw size and what your dentist designs for your specific bite.
Can All on 4 implants fail?
Yes, but failure rates are low. Long-term studies show implant survival rates above 94 percent at 10 years. The most common reasons for failure are smoking, uncontrolled diabetes, poor oral hygiene, and bone loss after surgery. Following your dentist’s care instructions reduces risk significantly.
Do All on 4 implants look natural?
Yes. The prosthesis is custom-made to match your face shape, skin tone, and the natural look you want. Modern zirconia and ceramic materials closely match real tooth colour and texture. Most people can’t tell the difference unless you tell them.
Can you eat normally with All on 4?
After the healing period, yes. You start on soft foods for 6 to 12 weeks after surgery. Once your permanent prosthesis is fitted, you can eat most foods including meat, bread, fruit, and crunchy vegetables. Very hard foods like raw carrots or crusty bread should be bitten carefully. Extremely hard foods like nuts, hard lollies, or ice are best avoided to protect the prosthesis.
How long do All on 4 implants last?
The titanium implant posts can last a lifetime. The prosthesis (the teeth part) typically lasts 10 to 20 years before needing replacement, depending on materials and care. Zirconia lasts longer than acrylic. Your dentist checks the prosthesis at every 6-month visit for wear and fit.
Is All on 4 covered by health insurance in Australia?
Private health extras cover varies widely. Some funds contribute to implants under major dental, typically up to a yearly limit of $1,000 to $3,000. This covers a portion of the cost, not the full amount. Call your fund before your consultation to find out exactly what you’re covered for.
