Why you should have a high tech video exam:
|
||||||||||||||||||||
 |
 |
| Leaky filling: notice blue-gray shadow on the lower right corner of the tooth | Old, leaking filling removed: Notice the deep, black decay in center of the tooth. |
 |
 |
| With the camera fixed in position, you can see decay under the tooth point in the upper right side. | A red food dye cavity detector marks the spot of decay under the lower right tooth point. |
 |
 |
| See where the decay was removed under the formerly gray tooth point. | Laser bonded filling: The blue-gray shadow is gone, even though the part of the tooth that had the blue-gray color is still there |
 |
 |
| This old filling was removed because of a "gray shadow." The outside of the filling looks nice and shiny. However... | ...The inside of the filling, where it was leaking and allowing decay, shows the black bacterial smear. |
