A dental crown becomes necessary when a tooth has weakened due to decay or fracture. It can also be used for cosmetic purposes.
A dental crown is placed by first grinding away the tooth so that it is smaller. A crown or cap is then placed over the tooth and secured.
If you are missing one or more teeth, your dentist may suggest the use of a fixed bridge and dental crowns.
Since the gap left by a missing tooth can cause the remaining teeth to shift or move, it is important for your oral health to replace the missing tooth or teeth; and fixed bridges are one of the solutions for doing so.
Bridges consist of a pontic (artificial tooth) and crowns – which are “caps” that go over the teeth on both sides of the bridge and serve as anchors to stabilize the bridge. Traditional bridges are usually made from porcelain fused to metal or ceramics.
