Your appearance is one reason. Another is that the gap left by 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.

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.

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.

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.

There are other options, such as using a combination of crowns and partial dentures that are well disguised. You can also have teeth implanted, ask your dentist for more information.

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. Remember that it’s as important to care for your remaining teeth as it is to replace the missing ones.
