An inlay or onlay is used for the same reasons as a filling or crown: broken or fractured teeth/fillings, decayed teeth, large fillings, etc. However, an inlay or onlay is used specifically when the tooth needs to be repaired from a large defective filling or when there is enough tooth structure left after decay is removed that a crown is not necessary.
An inlay restoration is a custom-made filling made of porcelain. Inlays are an ideal alternative to composite fillings because of its durability and lifespan. An onlay is also a custom-made restoration made of porcelain, but is large enough to be a partial crown. Onlays are often used when there is enough tooth structure left that a crown is no longer considered.
The dentists at Las Positas Family Dental will be able to discuss which option will benefit your dental needs.
