Crowns
If a natural tooth has been severely destroyed by caries, for instance, it can be preserved with an artificial dental crown. However, the prerequisite for this is the presence of the natural tooth root and some remaining tooth substance to attach the crown.
Even after root canal treatment, the tooth is usually crowned with an artificial crown to protect it from fracture. Dental crowns are usually made of gold, metal or ceramic (zirconium).
Bridges
A dental bridge is used to close gaps between teeth.
If neighbouring teeth are still present, they are ground down by your dentist during treatment so that a dental bridge can be attached to them.
Dental bridges can be made of metal or ceramic, just like dental crowns. Whether gaps between teeth are closed by bridges or implant-supported dentures should be decided on an individual basis. Dental bridges are usually a cheaper replacement for broken teeth.
