Is a Dental Bridge Right for You? Information on Types, Costs and More

7 Shares

If you are missing one or more teeth, your dental surgeon may suggest fitting a prosthetic device to fill the gap. Several solutions are available nowadays including a dental bridge, denture, or tooth implant plus crown.

But how do you know which is the best replacement tooth option for you? In this guide we focus on bridges – a way of filling a gap of one or two teeth between two healthy teeth.

We’ll answer your questions about tooth bridges including:

  • What is a dental bridge?
  • Can I get a dental bridge for front teeth?
  • What’s the difference between a bridge, implant and denture?
  • What are the advantages and disadvantages of these different options?
  • How much does a tooth bridge cost in the UK?
  • What’s the difference between a traditional fixed bridge and a bonded bridge?

We have made this guide to teeth bridges as comprehensive as possible so you can find all the information you need in one place. We hope this helps you decide whether a bridge is the best option for you.

What is a dental bridge?

A dental bridge is a type of dental prosthesis which literally bridges the gap between two teeth. If you have lost one or two teeth to decay or because of an accident, a bridge can make your smile complete again. Where more than two teeth in a row are missing, an implant-supported bridge may be an option – more on those later.

Tooth bridges come in a variety of materials and finishes. Metal alloys are usually the cheapest option, but they have the obvious disadvantage of looking nothing like natural teeth.

Porcelain and ceramic bridges, when made well, look exactly like natural teeth. However, they come at a much higher cost because of the materials and lab work involved.

A solution which balances cost with appearance is a bridge made from ceramic or porcelain fused to a metal base (as pictured). This type of bridge can lose its aesthetic appearance over time, though, and may not be as strong as pure ceramic. The best material for your bridge will depend on your budget and the position of your teeth.image of traditional dental bridge with 3 teeth

Types of dental bridges

Traditional tooth bridges use the adjacent teeth as anchors for the prosthesis. There are two ways to fit a bridge to the existing teeth: fixed or bonded.

Fixed bridge

A fixed bridge is the most common type of dental bridge as it provides a strong, durable way to replace one or two adjacent teeth.

The prosthesis used for a fixed bridge consists of a crown on either side and one or two pontics (artificial teeth) in the middle. The crowns are hollow and fit over the neighbouring teeth to secure the bridge in place.

In order for the crowns to fit properly, the anchor teeth must be filed down from their original size as part of the dental bridge procedure. These two teeth have to be strong enough to support the bridge and take the extra biting pressure. Dentists may perform root canal treatment on the anchor teeth before removing the necessary amount of enamel.

After preparing the anchor teeth, the next step in the dental bridge procedure is to take a dental impression. This is sent to a laboratory where your bridge is precisely made to measure. In the meantime, your dentist may provide a temporary bridge to protect the exposed teeth and gums.

Once your permanent bridge is ready, your dentist will position it in your mouth and ask you to test how it feels. Provided you’re happy with the fit, your dentist will fix it in place using a strong dental cement. Further visits are sometimes required to improve the fit, but not always.

The main drawback to a fixed bridge is having to ‘sacrifice’ two healthy teeth. If you later decide to replace your bridge with an implant, the adjacent teeth will require crowns since removal of enamel is permanent.

You’ll also need to take special care when cleaning and flossing around your bridge. Using a water flosser can make the process quicker, easier, and more effective.

Aside from that, a fixed bridge is a strong and durable solution. If you opt for a ceramic or porcelain bridge, nobody should be able to spot that the teeth aren’t natural.

Front teeth bridge

A dental bridge for front teeth may require two crowns on either side, since the biting pressure on the front incisors is so great.

If you are missing one or more front teeth, or have been told you need to have them extracted, your dentist will be able to advise you on the best type of front tooth bridge for you.

Bonded bridge

When there is only one tooth to replace, your dentist may fit a bonded bridge (also called a Maryland bridge).

Rather than being fitted over the adjacent teeth with crowns, this type of bridge has metal or porcelain ‘wings’ on each side which are bonded to the inner edge of the adjacent teeth.

A bonded bridge of course has the advantage of preserving the healthy adjacent teeth. The main downside is that it won’t be as strong as a fixed bridge. Over time the adhesive holding it in place can weaken, causing the bridge to break off or become loose.

With any type of bridge for teeth, it is only the crown of the tooth that is being replaced. The root remains absent, and this can cause the jawbone to recede over time.

Long-term, this may cause sagging around the face. If you choose to have implants at a later date, you may first need a bone graft. This is really the main dental bridge problem that patients need to be aware of.

Dental bridge vs. implant vs. denture

Bridges, implants and dentures are all dental solutions for the replacement of missing teeth. Each offers advantages and disadvantages over the others, which we have summarised below. However, the best way to determine which is right for you is to have a consultation with your dentist.

Teeth implants

Dental implants are placed directly into your jawbone, where your tooth root would have been. They are usually made from titanium, a very strong material which is biocompatible with our bodies (meaning there should be no allergic reaction or rejection of the implant).

An abutment is fitted to the implant, and this is what holds the crown (the replacement tooth) in place.

The main benefits of implants over bridges are:

  • They don’t affect the adjacent teeth
  • They are a more durable solution and can last a lifetime
  • It’s easier to maintain good oral hygiene with an implant (less chance of decay and gum disease)
  • They help maintain the structure of the jawbone and the shape of the face

On the downside, implants require some surgery and are much more expensive than a bridge fitted over teeth. If you take into account the lifetime cost and inconvenience of replacing your bridge, though, an implant may work out as a good investment in the long run.

Treatment time is another consideration for some patients. The process for placing a traditional implant takes several months, as the implant needs time to settle and fuse with the bone before the abutment and crown are attached. For some patients this is just too long to wait, so a bridge is the better solution.

If you are missing a tooth because of trauma, you may need additional time to heal before the implant process commences.

Implant-supported bridges

For patients who are missing several teeth in a row or whose remaining teeth aren’t healthy enough to be used as anchors, bridged implants may be an option. Dentists can install implants in place of anchor teeth and then fit a bridge (made from two crowns and one or two pontics) over them.

This option is more cost-effective than replacing each tooth with an individual implant, since it uses fewer implants.

Dentures

Dentures are what most people think of as ‘false teeth‘. They consist of one or more prosthetic teeth fixed to a frame made from plastic and metal which clips around existing teeth. The versatility of dentures means they can be made to fit around any number of remaining healthy teeth. People who have lost all their teeth can get a full set of dentures.

Dentures can replace one or more missing teeth

Although dentures are the most affordable option when it comes to replacing a missing tooth, they are also the least convenient to live with. Wearers must be careful about what they eat as certain foods will dislodge or damage dentures.

Although you can clean your teeth as normal while wearing a partial denture, you’ll still have to remove it sometimes for special cleaning. Full dentures, on the other hand, often must be removed and left in a cleaning solution overnight.

Because of the way our mouths change over time (especially when teeth are missing), dentures may only last for a few years before coming loose. If they are not replaced, they can become uncomfortable and cause mouth sores. There is also a chance of them slipping out mid-conversation.

Comparing the options

Below is a comparison table for the tooth replacement options described above:

Dental bridge Dental implant + crown Denture
Permanency Fixed to adjacent teeth; non-removable Implanted in the jaw bone, fixed in place Removable
Longevity 5-15 years, possibly longer 20+ years 5-10 years, possibly longer
Comfort Like natural teeth if fitted well Like natural teeth May become loose over time and cause discomfort
Appearance Like natural teeth (unless metal) Like natural teeth May look artificial; metal clips may be visible
Function Like natural teeth Like natural teeth Certain foods must be avoided; remove to clean
Cost Private: medium; NHS: £244.30 Private only: high Private: low; NHS: £244.30
Other pros/cons Requires removal of enamel on neighbouring teeth Involves surgery; small risk of infection Can slip out of place; easy to lose or damage while removed

Keep in mind that any kind of artificial tooth or tooth covering will be unaffected by teeth whitening. It’s important to remember this if you have a bridge that is visible when you smile.
Again, remember that the best way to determine which solution is right for you is to have a consultation with your dentist. Don’t have a regular dentist yet? Visit toothpick.com to locate an available dentist near you.

How much does a dental bridge cost?

Dental bridge costs will, of course, depend on the material used and the type of bridge chosen, as well as your dentist’s fees for consultations, fitting, etc. Your local surgery can probably give you an idea of prices prior to a consultation, either by phone or on their website.

Your dentist will certainly want to check your mouth and the state of your remaining teeth before confirming your treatment plan and providing a final cost estimate.

Cost of bridges in the UK

Bridges are one of the treatments offered on the NHS. The cost of a dental bridge with an NHS dentist is £256.50 – the band 3 treatment charge. You won’t get a choice of material for NHS bridges, and back teeth bridges are likely to be metal.

If you are unable to find an NHS dentist accepting patients, or you are ineligible for NHS treatment for some reason, you can visit a private dentist to get a bridge for your teeth. Although private treatment can be more costly, you’ll have more choice over the materials used and won’t have to deal with NHS waiting times.

The table below gives an idea of what you can expect to pay for different types of bridge with a private UK dentist:

Type of bridge Average cost (private treatment)
Traditional fixed crown and bridge £250 - £800 per unit
Bonded bridge £350 - £1,000
Implant-supported bridge (2 implants, 3-unit bridge) from £2,900

One way to save money on dental bridges, especially if you are getting implants, is to go abroad for your treatment. Teeth bridge costs and other dental care can be 50-70% less in countries like Hungary and Poland, yet the standard of care is often greater than you’re used to at home.

Do I need to replace a missing tooth?

There are many good reasons to fill that gap

With all these options to choose from, it may seem easier to do nothing at all and just live with a gap in your mouth – especially if it’s towards the back where nobody really sees it.

However, there are several reasons why it’s not a good idea to ignore the problem:

  • It’s harder to eat with a tooth missing
  • The surrounding teeth will be subject to extra pressure and wear
  • There is a greater risk of gum disease
  • It may affect your speech
  • The supporting jawbone will deteriorate over time and facial muscles may sag (this can be avoided with an implant, but not a bridge)

So if you or a loved one are missing one or more teeth, the question is not “Should I replace it?” but “How should I replace it?”

Conclusion

Since both dentures and bridges for teeth are covered by the NHS for UK patients, getting a prosthetic tooth needn’t break the bank. For those who want a natural-looking, permanent way to fill a gap between teeth, a bridge may be the best option. Once fitted, you can forget that it isn’t one of your natural teeth.

Implants are an even longer-lasting solution and they help retain the patient’s jaw bone and facial shape. However, implants are only available privately so cost a lot more. Fortunately, there are ways you can save money on dental implants if this is the option you wish to choose.
