An Onlay covers the biting surface and one or more cusps (the peaks of the tooth). An Onlay is used to restore a tooth that has lost much of its structure, but the tooth still has enough surface area to support a more conservative restoration.
The doctors at Mint Dental will recommend an onlay based on the extent of damage to the tooth.
An inlay is a special type of filling that may be used to restore the chewing surfaces of a back tooth. It is used when an existing filling has fractured, or when there is decay under an old large filling. An Inlay is also a conservative restoration. It is recommended based on how much tooth structure remains after removing all of the cavity or fractured restoration.
Drs. Nilay & Radhika Shah will consider the look and function of the inlay/onlay when choosing the material most suitable for you.
Some factors that are taken into consideration are:
Inlays & Onlays are made from tooth-colored materials, such as Porcelain, composite resin, and from gold alloys.
Gold Alloys may be used when high strength is needed and there is less concern about matching tooth color.
