Porcelain Crowns and Restorations
A badly decayed tooth might have several treatment options. One of them is placing a crown on the tooth to protect it from further decaying. This also can improve how the tooth can look while at the same time strengthening the tooth by the support of the material of the crown which can be made from porcelain fused to metal, all porcelain or the newer material zirconia. A crown can also be placed onto implants, if this is an available option for you.
If the decayed tooth would not be savable, it can be extracted and replaced with a bridge. A bridge is made by preparing the two teeth beside the missing tooth space to receive crowns that are connected by a fake tooth and would act to replace the missing or extracted tooth. This can also be made from porcelain fused to metal or zirconia. One advantage of replacing the missing tooth or teeth is to prevent shifting of the other teeth to further create problems with the bite, appearance, alignment, and the start of periodontal disease.
