If you’ve lost most or all of your teeth or you’re facing the prospect of full-mouth tooth loss, you’ve probably heard about All-on-4 dental implants. It’s the single biggest advancement in full-arch dentistry in the past two decades, and at Oxford Smiles in Marlborough, MA, we’ve watched it transform how our patients eat, smile, and feel about themselves.
All-on-4 is a full-arch dental restoration where four strategically placed titanium implants support a complete fixed bridge of teeth, replacing an entire upper or lower jaw of teeth in a single procedure, often the same day. No removable dentures. No adhesives. No sliding when you eat.
This guide answers every question new patients ask: candidacy, the procedure step-by-step, recovery, longevity, cost, and how All-on-4 compares to traditional dentures and other implant options.
📞 Curious if you’re a candidate? Call Oxford Smiles at (508) 290-8714 for an All-on-4 consultation, including 3D imaging, with Dr. Aditya Mehta.
What Are All-on-4 Dental Implants?
The “4” refers to the four titanium implants that anchor a permanent, fixed prosthetic arch of 10–14 teeth. Two implants are placed at the front of the jaw, where bone is naturally densest. The other two are placed at the back at a tilted angle, typically 30–45 degrees, to maximize the use of available bone without needing a sinus lift or extensive bone grafting.
That tilted-implant approach is what makes All-on-4 revolutionary. It allows patients with bone loss who would have been turned away from traditional implants 20 years ago to walk in with no teeth and walk out with a full set of fixed teeth in a single day.
How Is All-on-4 Different from Traditional Dentures?
| Feature | Traditional Dentures | All-on-4 Implants |
| How do they stay in place | Suction, adhesive, and partially the gums | Anchored permanently to your jawbone |
| Bone preservation | No bone shrinks over time | Yes, implants stimulate bone like natural roots |
| Eating ability | ~25% of natural bite force | ~90% of natural bite force |
| Speech | Can affect pronunciation | Speak naturally |
| Removal | Yes, daily | No fixed in place |
| Lifespan | 5–8 years before replacement | 20–30+ years with care |
| Daily care | Soak overnight, adhesives | Brush and floss like natural teeth |
Are You a Candidate for All-on-4?
You may be a strong candidate if any of these describe you:
- You’ve lost most of your upper or lower teeth
- You wear dentures and are tired of slipping, sore spots, or food restrictions
- Your remaining teeth are failing due to advanced gum disease or decay
- You’ve been told you don’t have enough bone for traditional implants
- You want a permanent, fixed solution, not something you take out
You May Need Additional Planning If:
- You have uncontrolled diabetes or other systemic conditions (we’ll coordinate with your physician)
- You’re a heavy smoker (we’ll discuss success rates honestly)
- You have severe bone loss (a custom approach with extra implants may be safer)
The only way to know for sure is a consultation with 3D imaging. Many patients who were told “no” by other dentists turn out to be excellent All-on-4 candidates once we see their bone in three dimensions.
The All-on-4 Procedure: Step by Step
Here’s exactly what to expect from your first consultation to your final permanent teeth.
Step 1: Initial Consultation and 3D Imaging (Day 1)
You’ll meet with Dr. Mehta for a comprehensive exam. We take a panoramic X-ray and a 3D CBCT scan, which lets us see your jawbone in three dimensions. This is where we determine whether All-on-4 is right for you, identify the ideal implant positions, and design your future smile digitally.
Step 2: Treatment Planning and Custom Smile Design (Days 1–14)
Using the 3D data, we plan exactly where each implant will go for maximum stability. We also work with our lab to design your temporary teeth to the shape, size, and shade you want.
Step 3: Surgery Day (Hours 1–4)
On surgery day, you arrive without permanent teeth and leave with a full set. Here’s the sequence:
- Sedation and anesthesia. Most patients choose oral or IV sedation for comfort.
- Tooth removal. If any failing teeth remain, they’re extracted at the start of the appointment.
- Bone preparation. We smooth and prepare the jawbone for implant placement.
- Implant placement. The four implants are placed using computer-guided precision. The angled placement at the back avoids critical anatomy like the sinus or nerve.
- Temporary teeth. A high-quality temporary bridge is attached to the implants the same day.
You leave with a beautiful, functional set of teeth, which we call “teeth in a day.”
Step 4: Healing Period (3–6 Months)
During this time, the implants fuse with your jawbone, a process called osseointegration. You’ll eat softer foods for the first few weeks, then gradually return to most normal foods. Follow-up visits ensure healing is on track.
Step 5: Final Permanent Bridge (Month 4–6)
Once healing is complete, we replace the temporary with your final, custom-crafted permanent bridge, typically zirconia or hybrid acrylic, designed to last decades.
What Is All-on-4 Recovery Really Like?
Most patients are surprised at how manageable recovery is. Here’s a realistic timeline:
- Day 1 (surgery day): You’ll feel numb and tired from sedation. Plan to rest. Soft food only.
- Days 2–3: Some swelling and bruising peak at 48 hours, then improve daily. Manage with prescribed medication and ice.
- Days 4–7: Most patients return to work this week. Stick with soft foods (pasta, eggs, smoothies, fish).
- Weeks 2–4: Swelling resolved. You can chew most foods comfortably.
- Months 1–6: Healing continues underneath. Bite force builds gradually as bone integrates.
- After the final bridge: Eat almost anything you’d eat with natural teeth, apples, steak, and corn on the cob.
Pain is typically less than patients expect. Most describe day 2–3 discomfort as “moderate, not severe,” and well-controlled with medication.
How Much Does All-on-4 Cost in Marlborough?
In 2026, All-on-4 in the Marlborough area typically costs $20,000–$30,000 per arch. Full-mouth (upper + lower) restoration runs $40,000–$60,000.

Insurance and Financing for All-on-4
Most dental insurance plans contribute meaningfully to All-on-4, even if they label “implants” as elective. Common covered components:
- Extractions (often fully covered)
- The crown/bridge component (typically 40–50% covered after deductible)
- Diagnostic imaging and exams
- Treatment of gum disease before implant placement
We verify your benefits in advance and submit any necessary pre-authorizations on your behalf.
Financing Options
- CareCredit Healthcare credit card with 0% promotional financing
- Sunbit High approval rates, soft credit pulls, terms up to 72 months
- LendingClub Longer-term healthcare loans for full mouth cases
A typical All-on-4 case on a 60-month plan works out to $400–$600/month, comparable to a car payment, for teeth that may last the rest of your life.
How Long Do All-on-4 Implants Last?
The implants themselves, properly placed, in healthy bone, with good home care, can last 25+ years and often a lifetime. The bridge that sits on top will eventually need refurbishment or replacement, typically after 15–20 years.
The single biggest factor in long-term success is routine professional cleanings and home hygiene. We’ll teach you exactly how to clean around your implants with floss threaders and a water flosser. Plan on coming in every 4–6 months for a hygiene visit.
What Are the Risks and Downsides of All-on-4?
We believe in honest patient education. All-on-4 isn’t perfect for everyone:
- It’s a major procedure. Even with sedation, it’s surgery. Recovery takes weeks.
- Upfront cost is significant even with financing.
- If one implant fails (rare under 5%), the entire bridge may need to be removed temporarily for repair.
- Severe bruxism or grinding can shorten the life of the bridge unless you wear a night guard.
- Smoking dramatically reduces success rates. Quitting before and after surgery is strongly recommended.
We’ll talk through every concern at your consultation so you can make a confident decision.

Frequently Asked Questions
Is All-on-4 right for me if I’ve worn dentures for years?
Often, yes, and patients tell us it’s life-changing. We’ll assess your remaining bone and discuss whether All-on-4 or a similar full-arch option fits best.
Can I get All-on-4 with no bone?
“No bone” is rare. Even patients with significant bone loss usually have enough at the front of the jaw, where two of the four implants go. The angled rear implants utilize bone at the back without grafting. In severe cases, “zygomatic implants” or other approaches may be needed; we’ll guide you.
How long does the All-on-4 surgery take?
Typically 2–4 hours per arch, depending on whether extractions are needed.
Will I really have teeth the same day?
Yes. You leave the office with a fully attached, fixed temporary bridge. The final permanent bridge comes after healing.
Does All-on-4 hurt?
Surgery is painless thanks to local anesthetics and sedation. Recovery discomfort is moderate and well-controlled with medication for most patients.
Can I eat normally with All-on-4?
After full healing, yes, about 90% of natural bite force returns. Most foods are fine. Avoid extremely hard items like ice or hard candy.
How do I clean All-on-4 teeth?
Brush twice daily, use a water flosser daily, and use floss threaders to clean under the bridge. Professional cleanings every 4–6 months are essential.
What if an implant fails?
Implant failure is uncommon, under 5% in healthy candidates. If it happens, we can typically replace the failed implant without replacing the bridge.
Is All-on-4 covered by Medicare?
Standard Medicare doesn’t cover dental implants, but some Medicare Advantage plans do offer partial coverage. We’ll check on your behalf.
