Tooth Colored Restorations

What are Inlays / Onlays & White Fillings?

inlay ---------- onlay ---------- crown

Inlays and Onlays are restorations that are made to rear teeth that have a mild to moderate amount of decay. They are made of composite resin material, porcelain, or gold by a dental laboratory. Once completed, Dr. Naz will bond them to the tooth.

  • an inlay sits in a hole inside the tooth
  • an onlay sits on top of the tooth to build up its shape.
  • They can also be used to:
  • Restore teeth that are cracked or fractured if the damage is not severe enough to require a dental crown.
  • Replace metal fillings for patients who desire a more natural looking smile.
  • Their use helps to conserve much of the natural tooth structure.


Treatment involves isolating the tooth and removing any old fillings or damaged tooth structure under local anesthesia. Dr. Naz makes an impression of the tooth, then the inlay or onlay is created from porcelain, gold, or composite resin material. The inlay/onlay is cemented securely into place. Dr. Naz may make adjustments to ensure the tooth is comfortable to bite on.

Benefits of Dental Inlays and Onlays and White Fillings

In treating dental decay, inlays and onlays help to eliminate tooth sensitivity and eventual tooth loss. Inlays and onlays also offer the following benefits:

  • Made from tooth-colored material, inlays and onlays are virtually invisible.
  • Unlike metal fillings, inlays and onlays will not expand or contract in response to temperature changes caused by hot or cold foods diminishing the possibility of fracture.
  • Inlays and onlays requires less tooth reduction than metal fillings allowing Dr. Naz to conserve more natural tooth structure.
  • The durable material from which inlays and onlays are made helps them last much longer than that of conventional amalgam fillings.
  • Inlays and onlays can replace silver fillings to create a healthier, more natural-looking smile.
  • By saving decayed teeth, inlays and onlays prevent the need for more extensive treatment later on.

Inlays and onlays usually take 2-3 appointments.
