After decay is removed from a tooth, something must be placed to replace the lost tooth structure.

Fillings: Fillings are the most common restorative procedure.

Inlays and onlays: In addition to fillings, lab fabricated inlays and onlays are sometimes used. Although many patients think of these as fillings as well, they are actually different since they are laboratory fabricated. Inlays and Onlays are custom made and are a more permanent and ideal resoration.

White fillings: White fillings are an alternative to silver (amalgam) fillings. White fillings are made of a strong composite resin that is matched to the surrounding tooth color. In the past, white fillings were placed only on front teeth, but recently a stronger more durable material has been developed that can withstand the chewing pressure of back teeth. They are still less durable and more technique sensitive than silver fillings. They can be utilized in limited situations.

Silver (amalgam) fillings: Silver fillings have been used reliably for many years. Typically, silver fillings are placed on back teeth (molars). They are an economical way of providing a lasting restoration for most cavities. The material is specially formulated to withstand years of chewing pressure. For more information on amalgan fillings, visit the ADA website.

White Porcelain or Resin inlay or onlay: A porcelain or resin inlay or onlay is used when the cavity is too big for a filling, but isn't so big that a crown is required. An inlay is a filling within the cusp tips of the tooth. Onlays (also known as overlays) will overlay one or more cusps in order to protect and strengthen the tooth. The restoration fit better and last longer than white or silver fillings.

An inlay or onlay may also be made of gold.
