In case if there are a few teeth missing, then a dental bridge comes into play. Bridges can compensate for multiple missing teeth. The empty spaces left by the broken or missing teeth are covered up by placing artificial teeth, and a bridge is basically supported by two crowns. These crowns tend to rely upon the teeth, which have been left over, and thus, all the gaps are accordingly covered by these bridges. The pillars, which hold up the bridge, are usually made using implants or existing teeth. 

Nowadays, experienced dentists are able to make pillars using a hybrid of the existing teeth and implants. The sole purpose of bridges is not only to safeguard the outer facade of the teeth, but also to preserve the withdrawal of gingival from the teeth. The durability and the stability of bridges are much more than that of crowns solely. There is a wide variety of bridges available. Some of these are made using metal ceramic, whereas the others are made using zircon. Zircon bridges are much better than metal ceramic bridges in terms of properties and color. On the whole, if the process goes smoothly, then the teeth stay durable for a long period of time.
