All-on-4 is a way of replacing a whole arch of teeth — upper, lower or both — with a fixed bridge supported by just four dental implants. It is designed for people who have lost most or all of their teeth, or whose remaining teeth are failing, and who want a stable, permanent alternative to a removable denture. This guide explains how All-on-4 works, who it is for, what the process involves, and how to think about the cost.
What is All-on-4?
An implant is a small titanium post placed into the jawbone, where it fuses with the bone to act like a tooth root. With All-on-4, four implants are positioned across the arch — usually two straight at the front and two angled at the back — to provide maximum support from the bone you have. A full bridge of new teeth is then fixed onto those implants. Because the teeth are screwed in place, they do not come out at night like a denture.
Who is All-on-4 for?
People who have lost all or most of the teeth in an arch.
Denture wearers who are tired of movement, sore spots, or adhesives.
Patients whose remaining teeth are failing because of gum disease or decay.
Those who want a fixed, long-term solution and are generally healthy enough for minor oral surgery.
Because the implants are angled to use the densest available bone, All-on-4 can often suit people who were told they had too little bone for conventional implants, sometimes avoiding the need for bone grafting. A consultation and a 3D scan confirm whether it is right for you.
The All-on-4 process and timeline
Treatment usually begins with a detailed assessment: photographs, X-rays and a 3D scan to plan the implant positions precisely. On the day of surgery, any failing teeth are removed, the four implants are placed, and a fixed temporary set of teeth is often fitted so you do not leave without teeth. Over the following months the implants integrate with the bone, and once healing is complete a final, custom bridge is fitted. From start to final teeth, the process commonly spans a few months, most of which is healing time rather than appointments.
At Pear Tree, dental implants and full-arch restoration is led by our principal dentists. Dr Javaad Mirza (MD, BDS, GDC 290378) has a special interest in cosmetic dentistry, including implants, veneers and orthodontics, and will talk you through what is realistic for your teeth at your consultation.
Pros and trade-offs
Fixed teeth that look and function much like natural teeth, with no nightly removal.
Often avoids bone grafting by using angled implants.
A full arch supported by four implants rather than one implant per tooth, which keeps it more affordable than replacing every tooth individually.
It is a surgical procedure, so it requires healing time and a commitment to aftercare.
Like natural teeth, the implants and gums need ongoing cleaning and regular reviews to last.
How much does All-on-4 cost?
All-on-4 is a tailored, full-arch treatment, so the fee is price on application — it depends on your scans, the number of arches and the final materials, and is confirmed in writing after your assessment. For context, a single implant at Pear Tree Dental starts from £2,500 and an implant bridge from £8,500. Because All-on-4 restores a complete arch on four implants rather than one per tooth, it is usually far more cost-effective than replacing every missing tooth separately.
Looking after All-on-4
Fixed implant teeth still need daily cleaning — brushing, plus cleaning underneath the bridge with the tools your dentist recommends — and regular professional reviews and hygiene visits. Well cared for, implants are a long-term solution, and looking after them is the single biggest factor in how long they last.
Spreading the cost with membership
If you are a regular patient, it is worth knowing that Pear Tree membership plans start from £10.95 a month and include your routine check-ups and hygiene visits, plus 10% off selected treatments. For families, the Family Plan covers everyone from £49.50 a month. Membership helps spread the cost of looking after your teeth and can reduce the price of further work — ask us which treatments are included.

FAQ
Q: How much do All-on-4 dental implants cost? A: At Pear Tree Dental the fee is price on application, because it depends on your scans, how many arches are treated and the final materials. You receive a written quote after your assessment. For comparison, single implants start from £2,500.
Q: Do you leave the appointment with no teeth? A: Usually not. A fixed temporary set of teeth is often fitted on the day of surgery, so you heal with teeth in place before the final bridge is made.
Q: How long do All-on-4 implants last? A: With good cleaning and regular reviews, implants are designed as a long-term solution and can last many years. Daily care and professional maintenance are the biggest factors in their lifespan.
Q: Is All-on-4 painful? A: The surgery is carried out with local anaesthetic and, where appropriate, additional comfort options, so the procedure itself should not hurt. Some swelling and soreness afterwards is normal and managed with simple pain relief and aftercare advice.
Q: Am I suitable if I was told I don’t have enough bone? A: Possibly. All-on-4 uses angled implants to make the most of available bone and can sometimes avoid grafting. A 3D scan at your consultation confirms it. Book online or call 0115 931 2935.
