Losing one or more teeth can affect far more than your smile. Missing teeth may change the way you eat and speak, place extra pressure on the remaining teeth and, in some cases, lead to changes in the jawbone and surrounding gum tissue.
Fortunately, there are several reliable tooth replacement options available. The three most common are dental implants, dental bridges and dentures. Each has different advantages, limitations and treatment requirements, so the right choice will depend on your oral health, the number and position of the missing teeth, your priorities and your budget.
In this guide, we compare dental implants vs bridges vs dentures to help you understand the main differences before discussing your options with a dentist.
What are the main options for replacing missing teeth?
The most suitable treatment often depends on whether you are replacing one tooth, several teeth or a complete arch.
Dental implants
Dental implants are small titanium fixtures placed into the jawbone. Once the implant has integrated with the surrounding bone, it can support a crown, bridge or denture.
Implants are designed to replace the root of a missing tooth as well as the visible part above the gum. This helps provide strong support without relying on neighbouring teeth.
You can read more about how implant treatment works in our article, Understanding Dental Implants.
Dental bridges
A dental bridge replaces a missing tooth, or sometimes several teeth, with a fixed restoration. The replacement tooth is supported by the teeth or implants on either side of the gap.
A conventional bridge usually involves preparing the neighbouring teeth for crowns. A resin-bonded bridge may require less preparation and is often attached to the back of an adjacent tooth, although it is not suitable in every situation.
Dentures
Dentures are removable appliances used to replace several missing teeth or a complete set of teeth. They may be made from acrylic, metal or a combination of materials.
A partial denture fills spaces between remaining teeth, while a full denture replaces all the teeth in the upper or lower jaw. Dentures can also be supported by dental implants to improve their stability.
Dental implants vs bridges vs dentures: a quick comparison
Consideration | Dental implants | Dental bridges | Dentures |
Fixed or removable | Usually fixed | Fixed | Usually removable |
Support | Jawbone | Adjacent teeth or implants | Gums, remaining teeth or implants |
Effect on nearby teeth | Usually no preparation required | Adjacent teeth may need preparation | Usually little or no tooth preparation |
Treatment complexity | Requires surgery and healing | Usually no surgery unless implant-supported | Generally less invasive |
Stability | Very stable once integrated | Stable and fixed | Can move unless implant-supported |
Cleaning | Brushing plus specialist cleaning around the implant | Cleaning beneath the bridge is essential | Must be removed and cleaned regularly |
Suitable for | One, several or all missing teeth | Often one or several adjacent missing teeth | Several or all missing teeth |
Bone preservation | Can help maintain bone around the implant | Does not replace the tooth root | Does not replace the tooth root |
Which option feels most like natural teeth?
For many patients, dental implants provide the closest feeling to natural teeth because they are secured within the jawbone. An implant-supported crown does not usually move during eating or speaking, and it can be brushed in a similar way to a natural tooth.
A well-designed bridge can also look and feel natural. Because it is fixed in place, patients do not need to remove it for cleaning. However, additional care is needed to clean beneath the replacement tooth.
Modern dentures can offer a significant improvement in appearance and function, but they may take time to get used to. Some movement is possible, particularly with complete lower dentures. Implant-supported dentures can provide greater stability for suitable patients.
Which option looks best?
All three treatments can produce attractive results when they are carefully planned.
Dental implant crowns and bridges can be shaped and shaded to blend with the surrounding teeth. Because each restoration emerges from the gum area, implants can create a natural appearance, although the final result depends on the amount of available bone and gum tissue.
Dental bridges can also provide excellent aesthetic results, particularly when the supporting teeth are healthy and the surrounding gum levels are stable.
Dentures can restore the appearance of the teeth, lips and facial profile, especially when several teeth have been missing for some time. Their appearance depends on the design, fit and quality of the materials used.
The best cosmetic result is not always linked to one particular treatment. It depends on detailed planning and the condition of the teeth, gums and jawbone.
How does maintenance differ?
Every tooth replacement option requires ongoing care.
Caring for dental implants
Dental implants cannot develop decay, but the gums and bone around them can still be affected by inflammation and disease. Good plaque control, regular dental examinations and professional maintenance are therefore essential.
Patients need to brush around the implant restoration and may be advised to use interdental brushes, floss or another cleaning aid.
Caring for a dental bridge
A bridge should be brushed twice a day, with particular attention paid to the supporting teeth. The area beneath the replacement tooth must also be cleaned using floss threaders, interdental brushes or another recommended device.
If plaque builds up around the supporting teeth, decay or gum disease may develop and compromise the bridge.
Caring for dentures
Dentures should normally be removed for cleaning and cleaned separately from the natural teeth and gums. They also need to be checked periodically because the shape of the mouth can change over time.
A denture that becomes loose, uncomfortable or damaged should be assessed rather than adjusted at home.
Which option lasts the longest?
The lifespan of any restoration varies from patient to patient. Oral hygiene, smoking, gum health, bite forces, tooth grinding and attendance for routine maintenance can all affect the result.
Dental implants can provide a long-term solution when they are well planned and maintained. However, the crown, bridge or denture attached to an implant may eventually require repair or replacement.
Dental bridges can also last for many years, but their success depends partly on the health of the supporting teeth. If one of these teeth develops decay, gum disease or a fracture, the bridge may be affected.
Dentures often require adjustment, relining or replacement as the gums and jawbone change. This does not necessarily mean that dentures are an unsuitable choice; it simply reflects the fact that they are removable appliances resting on tissues that naturally alter over time.
Which treatment is the least complex?
Dentures are generally the least invasive option because they do not usually require surgery. They can therefore be suitable for patients who prefer a removable solution, need to replace several teeth or are unable to undergo implant treatment.
A dental bridge may be completed more quickly than an implant because there is no need to wait for an implant to integrate with the bone. However, a conventional bridge may require significant preparation of the supporting teeth.
Dental implant treatment is usually more complex. It involves assessment, planning, implant placement, a healing period and the fitting of the final restoration. Some patients may also require bone grafting or gum treatment before or during the implant process.
The more complex treatment is not automatically the best treatment. The aim is to select the most appropriate and predictable option for the individual patient.
Am I suitable for dental implants?
Many adults can be considered for implant treatment, but suitability must be assessed carefully.
Important factors include:
- the amount and quality of available jawbone;
- the health of the gums;
- general medical health;
- smoking;
- oral hygiene;
- the way the teeth meet;
- tooth grinding or clenching;
- the patient’s expectations and ability to attend maintenance appointments.
A lack of bone does not always rule out treatment, as grafting may sometimes be possible. However, each case requires an individual clinical and radiographic assessment.
Our guide, Who Is Suitable for Dental Implants?, explains these considerations in more detail.
When might a dental bridge be the best choice?
A bridge may be worth considering when:
- one or more teeth are missing in the same area;
- the teeth beside the gap already have large fillings or crowns;
- the patient would prefer a fixed restoration without implant surgery;
- implant treatment is not suitable;
- the available bone or gum anatomy makes implant treatment more complicated;
- a faster treatment route is a priority.
One important consideration in the dental bridge vs implant decision is the condition of the neighbouring teeth. Preparing completely healthy teeth to support a bridge may be less desirable than placing an implant, whereas using teeth that already require crowns may be reasonable.
When might dentures be the best choice?
Dentures may be suitable when:
- several or all teeth need to be replaced;
- a removable option is preferred;
- surgery is not appropriate;
- bone loss limits other treatment options;
- the patient is looking for a less complex initial treatment;
- appearance and function need to be restored relatively quickly.
When comparing dentures vs implants, it is also important to remember that the two treatments can be combined. A small number of implants may be used to stabilise a denture, reducing movement and improving confidence when eating and speaking.
What is the best option for missing teeth?
There is no single treatment that is best for every patient.
Dental implants may be the preferred option for someone seeking a fixed restoration that does not rely on adjacent teeth. A bridge may be more appropriate when the neighbouring teeth would benefit from crowns or when surgery is not desired. Dentures may offer a practical solution when many teeth are missing or when a removable treatment is preferred.
In some complex cases, a combination of treatments may provide the best result. For example, implants may be used in one area while a bridge or partial denture is used elsewhere.
A consultation with a clinician experienced in restorative dentistry allows the teeth, gums, bite and jawbone to be assessed together. This is especially important when there are several possible options or when previous dental treatment has failed.
