Crown – (or cap) is a covering that encases the entire tooth surface restoring it to its original shape and size. A crown protects and strengthens tooth structure that cannot be restored with fillings or other types of restorations. Crowns are needed for broken teeth, teeth with fractured fillings, extensive decay, teeth that have had root canal therapy, teeth that have too large of filling, to restore an implant, and for cosmetic reasons. They are highly durable and will last many years, but like most dental restorations, they may eventually need to be replaced.
Bridge- A dental bridge is a fixed (non-removable) appliance and is an excellent way to replace missing teeth. A dental bridge is a false tooth or teeth, known as a pontic, which is fused between two porcelain crowns to fill in the area left by a missing tooth or teeth. Cleaning around your bridge is just as important as cleaning every other tooth in your mouth. A bridge is one of a few options for replacing missing teeth!
Onlay -Like a crown, an onlay is used when a tooth is too damaged or decayed for a filling or other procedure. It’s similar to a crown, in that it covers and protects the tooth surface. But where a crown covers the entire tooth, the onlay covers only the cusps and biting surface. An onlay is sometimes also referred to as a partial crown. Onlays are a conservative alternative to crowns because good tooth structure is preserved!
