From Dentures to Fixed Teeth: Why Patients Choose All-on-4 Implants at Hertfordshire Dental Group
4th March 2026
At Hertfordshire Dental Group, we’re proud to have helped hundreds of patients enjoy life again after years of struggling with missing teeth, uncomfortable dentures, or failing dental work. For many people, loose or poorly fitting dentures can make everyday activities like eating, speaking, and smiling feel difficult or frustrating.
Today, more patients are choosing a modern and permanent alternative to dentures: All-on-4 dental implants, often referred to as “Teeth in a Day.” This innovative treatment allows an entire arch of teeth to be replaced with a fixed, natural-looking smile, supported securely by as few as four dental implants.
In this guide, we explain how All-on-4 dental implants work, their key benefits, and why so many patients across Hertfordshire are choosing this life-changing treatment over removable dentures.
What Are All-on-4 Dental Implants?
All-on-4 is an advanced dental implant technique designed for patients who have lost most or all of their teeth in the upper or lower jaw, or whose remaining teeth are no longer healthy enough to keep.
Instead of placing an implant for every missing tooth, this method uses a minimum of four carefully positioned implants to support a full set of fixed replacement teeth. In some cases, six implants may be recommended depending on the patient’s bone structure and treatment needs.
These implants act as strong foundations within the jawbone, allowing a full arch of teeth to be securely attached. The result is a stable, natural-looking smile that remains firmly in place when eating, speaking, or laughing.
Teeth in a Day: How the Procedure Works
One of the most appealing aspects of the All-on-4 system is the possibility of receiving new teeth on the same day as implant surgery.
Using advanced digital planning and modern surgical techniques, the treatment is carefully mapped out before the procedure takes place. During surgery, the implants are placed strategically in areas of the jawbone that provide the best stability.
In many cases, a temporary but fully functional set of teeth can be attached to the implants on the very same day. This is why the treatment is commonly known as “Teeth in a Day.”
Patients can leave the practice with a confident smile while their implants gradually integrate with the bone during the healing phase. After around 3 months, once healing is complete, a final set of custom-crafted permanent teeth is fitted.
Here, Dr Roshwin Pereira Carvalho talks us through the All‑on‑4 process, who it’s suitable for, and how this smart procedure lets patients with failing teeth leave the same day with a renewed sense of confidence:
Key Benefits of All-on-4 Dental Implants
There are several reasons why All-on-4 implants have become one of the most popular full-arch restoration treatments available today.
Fixed, Natural-Looking Teeth
Unlike dentures, the replacement teeth are securely fixed in place. They do not slip, shift, or require adhesives.
Fewer Implants Required
A complete arch of teeth can often be supported by just four implants, making the procedure more efficient than placing individual implants for every missing tooth.
Often Avoids Bone Grafting
The angled placement of the implants allows dentists to make the most of the available bone, reducing or eliminating the need for bone grafting in many cases.
Faster Treatment Timeline
Because temporary teeth can often be fitted on the same day, patients do not have to spend months without teeth during the healing process.
Easy to Maintain
All-on-4 implants are cared for in a similar way to natural teeth. With regular brushing, good oral hygiene, and routine dental check-ups, they can remain healthy and functional for many years.
A Life-Changing Solution for Many Patients
For people who have struggled with uncomfortable dentures or deteriorating teeth, the All-on-4 approach can be truly transformative. Patients frequently report improvements in:
Confidence when smiling and speaking
Comfort when eating a wider range of foods
Facial support and overall appearance
Long-term oral health and stability
It can be particularly beneficial for individuals who have been told they may not be suitable for traditional dental implants due to bone loss.
