A bridge can replace one or several missing teeth. They consist of an artificial tooth/teeth attached to crowns on the teeth on each side of the gap. A bridge is usually made of tooth-colored materials such as a combination of porcelain fused to precious metal. Replacing missing teeth will help to maintain your oral health by preventing the remaining teeth from moving out of alignment and so damaging your smile. This may also cause tooth decay and gum disease and thus the possibility of further tooth loss. Receiving a bridge will usually involve two or more appointments. At the first appointment, your dentist will take an accurate impression of your teeth to make a temporary bridge for you to wear while the permanent bridge is being manufactured by a dental technician. After the appropriate area is numbed with local anaesthetic, teeth to which your bridge is to be secured on either side of the space are carefully reshaped. Impressions are then taken, and these are used as a template by a dental laboratory onto which they make your bridge. The shade of your surrounding teeth is selected, to have your new bridge look as natural as possible. After the final impression is taken your temporary bridge is cemented in place, with temporary cement. The final bridge is fitted to you about two weeks later, at the final and third visit. When your new bridge is ready, it is bonded into place in the same way that a crown is. If you are biting on the bridge, adjustments are made until the bite feels right. It may take a couple of weeks to become fully familiar with the feel of your new teeth. It is not uncommon that a few minor adjustments need to be made to improve your comfort, after the bridge, or indeed any dental restoration is fitted.
