What is All-on-4 Dental Implants?

All-on-4 dental implants is procedure for those who looking to restore their smile, quickly and permanently. If you’ve lost several teeth or are fed up of dentures that won’t stay put, then this treatment might be just what you need.

Often referred to as Teeth in a Day or Smile in a Day, this innovative treatment provides you with a fixed set of natural-looking teeth using only four implants. It’s designed to quickly and permanently restore your smile.

What Are All-on-4 Dental Implants?

The idea behind All-on-4 is as straight forward as the name suggests.

Compared to traditional methods where a separate implant is needed for every single missing tooth, this technique requires just four implants placed in your jaw to support a whole row of teeth. Two of these implants go right into the front of your jaw where the bone is strongest. The other two are angled towards the back for extra stability.

This smart setup means you end up with fewer implants but the bridge of teeth they hold feels just as solid as your natural ones. Plus, for many of our patients, this approach can help them skip extra surgeries like bone grafting.

While traditional implants often require months of multiple appointments, All-on-4 can be done in just one day. You walk in with failing or missing teeth and walk out with a beautiful, fixed smile that looks completely natural.

How Do All-on-4 Dental Implants Actually Work?

Each implant is essentially a small titanium post that serves as the root of a tooth. 

Once it’s placed into the bone, your body gradually bonds with it over time. Dentists refer to this process as osseointegration, but to put it simply, it just means the implant becomes a part of your jaw. 

With the All-on-4 procedure, the implants are installed and immediately connected to a temporary bridge of teeth. This way, you won’t have to go for months without teeth or depend on loose dentures. After a healing period, which typically lasts between three to six months, your permanent bridge is put in place. That’s when everything finally feels complete and settled.

Who Is a Good Candidate for All-on-4?

All-on-4 is designed for people who have lost most of their teeth, or know they will soon. It’s also ideal if you already wear dentures but hate the way they move about.

It can also be suitable for those who have been told they don’t have enough bone for traditional implants. Because the implants are angled, they make use of stronger parts of the jawbone. When the bone is really thin, options like zygomatic implants might be considered which are anchored higher up into the cheekbone.

Good gum health is important, and smoking can slow healing, so every patient is assessed carefully before treatment begins.

The Benefits of All-on-4 Implants

The most obvious benefit is that you get your smile back. You don’t need to worry about teeth slipping out of place or using glue to keep dentures in place. You can eat, speak and laugh without giving it a second thought.

They also help to protect the jawbone. When teeth are missing, bone naturally shrinks over time. This can make the face look older, where as implants stimulate the bone just like real roots, keeping it healthy and preserving your natural shape.

Another advantage is speed. With All-on-4, you avoid the drawn-out treatment of traditional implants where every tooth can need its own fixture. Most patients have their new smile fitted in just one visit.

All-on-4 Compared With Other Options

All-on-4 vs Traditional Dental Implants

Traditional implants usually need eight or more per jaw. This usually means extra surgery and a longer recovery. All-on-4 uses just four that are placed in strong areas of the bone. This method keeps the procedure quicker and less invasive.

All-on-4 vs Dentures

Dentures rest on the gums meaning they can move when you eat or talk. They also don’t protect the bone underneath, so over time the fit changes as the bone shrinks. All-on-4 is fixed in place, preserves bone, and feels just like natural teeth.

The Treatment Process at Smile London

Consultation and Planning

Your journey starts with a consultation. Scans and X-rays give us a clear picture of your jaw and bone structure. This allows us to design a treatment plan that’s personal to you.

Surgery Day

Any failing teeth are removed and the four implants are placed. A temporary set of fixed teeth is attached the same day, so you don’t leave the clinic without a smile.

Healing Phase

Over the next few months, the implants bond with the bone. During this time you will still be able to talk, smile & eat softer foods while the implants strengthen.

Final Bridge

Once healing is complete, your permanent bridge is fitted. It’s designed to look natural, match your facial features, and feel strong enough for everyday life.

Aftercare

Looking after All-on-4 implants is easy. You brush them as you would normal teeth. Some may use tools such as water flossers to reach around the implants too. Regular check-ups and hygiene visits are are a must in order to keep everything healthy.

How Long Do All-on-4 Implants Last?

All-on-4 dental implants are supposed to last a very long time, and with the right care they absolutely will do (potentially staying secure for decades). The bridge may potentially need replacing at some point due to natural wear but the implants themselves can last a lifetime.

Daily cleaning, quitting smoking, and routine check-ups all make a huge difference to how long they last. Patients who commit to maintenance usually enjoy their implants for many years without problems.

How Much Do All-on-4 Dental Implants Cost in London?

In London, the cost usually falls between £7,000 and £14,000 per arch. The exact figure will depend on how many teeth are being replaced, the type of bridge used, and whether any extra procedures are needed. At Smile London, finance plans are even available to help spread the cost.

Some clinics abroad advertise lower prices. However, overseas carries risks and especially if something goes wrong later. Having implants placed at a London clinic means ongoing care and peace of mind.

All-on-4 Dental Implant FAQs

Do All-on-4 implants hurt?
The procedure is done under local anaesthetic, with sedation if needed. Most people are surprised by how comfortable it is.

How long is recovery?
Some swelling or tenderness is normal, but it usually settles in a few days. Many patients go back to work within a week.

Do they look natural?
Yes. The bridge is designed to match your teeth in shape, size, and colour, so it blends in seamlessly.

How do I clean them?
You brush them like natural teeth. In some cases, we recommend special flossing tools or water flossers to keep everything spotless.

Are they suitable if I don’t have enough bone?
Often yes. Because of the angled placement, All-on-4 makes use of stronger parts of the jaw. For very low bone, zygomatic implants may be considered.

Can smokers have All-on-4 implants?
It is possible however smoking reduces the success rate and will slow healing. Cutting down or stopping completely is strongly advised.

When can I eat normally?
At the start, you’ll consume softer foods during healing. Once the implants have fused, you’ll be able to eat whatever you like again.
