Bridges

A bridge can be used to fill the space where a tooth has fallen out or been removed: A replacement tooth (or teeth), being fixed to the natural teeth at either side of the gap.

These are fixed restorations consisting of an artificial tooth used to restore a space then held in place on one or more adjacent support teeth. There are two main types of bridges, defined by the type of support structure connecting the artificial tooth and support teeth. With type one, adhesive bridges, a metal-wing connects to the artificial tooth and that wing is bound to the back of the support tooth with an adhesive agent. With type two, conventional bridges, rather than a metal-wing, a crown is used to sit over the support tooth. Your dentist will help you to select which option is more appropriate for your teeth, as this varies for different situations.

The procedure is similar to that for porcelain crowns. The dentist will prepare the support teeth to accommodate the bridge. In most adhesive bridge cases, tooth preparation is not required or it is minimal, as the metal wing takes up little space. Then an impression is taken and sent to the lab to construct the bridge for us to fit at a subsequent appointment.

Why should I replace missing teeth?

Your appearance is one reason. Another is that the gap left by a missing tooth can mean greater strain on the teeth at either side. A gap can also mean your 'bite' is affected, because the teeth next to the space can lean into the gap and alter the way the upper and lower teeth bite together. This can then lead to food getting packed into the gap, which causes both decay and gum disease.

How are missing teeth replaced?

This depends on the number of teeth missing and on where they are in the mouth. The condition of the other teeth also affects the decision.

There are two main two ways to replace the missing teeth. The first is with a removable false tooth or teeth - a partial denture. The second is with a fixed bridge. A bridge is usually used where there are fewer teeth to replace, or when the missing teeth are only on one side of the mouth.

Can I always have a bridge to replace missing teeth?

Yes, if you have enough strong teeth with good bone support. Your dentist will help you decide the best way of replacing your missing teeth within your budget.

What are bridges made of?

Bridges are usually made of a precious metal base. If the bridge will show, porcelain is then bonded to the base. Sometimes, there are other non-precious metals used in the base to reduce the cost.

Are bridges expensive?

Although a bridge may seem expensive it will last many years. It will also improve your appearance and bite. A bridge uses the considerable skill of the dentist and technician, and in this way, it's similar to ordering a piece of hand-made jewellery. The materials are also expensive so it's fair to say a bridge will not be the cheapest treatment you have ever had.

How do I look after my bridge?

You need to clean your bridge every day, to prevent problems such as bad breath and gum disease. You also have to clean under the false tooth every day. Your dentist or hygienist will show you how to use a bridge needle or special floss, as a normal toothbrush cannot reach.

Are there other methods for fixing false teeth?

There are other methods, such as using a combination of crowns and partial dentures that can keep the retaining clips out of sight.

Are there different types of bridge?

Yes, there are different types of bridge which use different fixing methods. Your dentist will choose the most effective and conservative bridge for your personal situation.

What is an adhesive bridge?

An adhesive bridge is a bridge which consists of a dummy tooth attached to a titanium wing. This wing glues onto the adjacent tooth.

What are the advantages over traditional crown-retained bridges?

Only minimal preparation of the adjacent tooth is required. This is much healthier for the supporting tooth than removing a large amount of enamel and dentine in order to make a retaining crown. Adhesive bridges are also much less expensive than crown retained bridges.

What are the disadvantages of adhesive bridges?

Adhesive bridges can only be stuck onto unfilled teeth or teeth with very small fillings. If a tooth is heavily filled then a crown retained bridge will be required.

An adhesive bridge cannot be fitted where a large number of teeth are due to be replaced. Adhesive bridges do not last as long as crown retained bridges.

How long will the bridge last?

On average the bridge will last around eight years. It will typically need re-cementing once during this period.

Will the bridge feel normal?

The retaining wing will probably feel very 'high' for the first few days. After a week or two the teeth will move slightly so that your 'bite' feels normal again.

How much do they cost?

It depends how many teeth are involved but the price for a bridge would typically be around £500-£600.
