Inlay, Onlays, and Crowns
A small cavity caused by dental caries or decay can be repaired with a filling such as composite bonding. Alternatively, it can be restored with an Inlay, which is a laboratory made filling out of a more durable ceramic or gold alloy which gets cemented into the cavity.
When the cavity is a little bigger and requires a larger restoration that covers the cusps of a tooth, it can be restored by a laboratory-made Onlay which gets cemented onto the tooth.
When the tooth requires extensive restoration, a Crown is made. This covers the entire tooth. Traditionally, they were made with porcelain fused to metal alloys. Newer all-ceramic materials offer greater strength without the darkness of the metal substructures. Our most popular ceramics are eMax and Zirconia. Some eMax crowns can be custom made by Dr. Deegan on the SAME DAY! No need to wear a temporary crown for weeks.
Crowns can be connected together to create bridges, which can permanently replace missing teeth. Typically, adjacent teeth (abutments) are crowned and connected together with pontic crowns (the missing teeth). Bridges can be made of porcelain fused to metal or all- ceramic materials.
Replacing missing teeth: It is important that missing teeth are replaced, especially back teeth, in order to keep the bite (occlusion) stable and the jaw and joints functioning properly. When missing teeth are not replaced, a trickle down effect occurs: adjacent and opposing teeth drift and tilt out of position; the supporting bone and gums may be ill affected; the front teeth will experience excessive forces leading to excessive wear, looseness, and/or flaring out of the front teeth; the TMJ may become stretched and strained; there could result a collapse of facial structures
