X-Ray of Tooth Decay

The tooth of interest in this dental xray is the upper right first molar. A dentist has restored this tooth in the past with an occlusal amalgam filling as shown by the radio-opaque (white) area. The blue arrow points to the large cavity on the mesial aspect of the tooth. Restorative treatment options available for the dentist in this instance range from an amalgam filling, composite, gold or porcelain onlay.
