Tooth Preparation
Preparation of a tooth for a crown involves permanently removing much of the tooth's original structure, including portions that might still be healthy and structurally sound. All currently available materials for making crowns are not as good as healthy, natural tooth structure, so teeth should only be crowned when an oral health-care professional has evaluated the tooth and decided that the overall value of the crown will outweigh the disadvantage of needing to remove some healthy parts of the tooth. This can be a very complex evaluation to make, so different dentists (trained at different institutions, with different experiences, and trained in different methods of treatment planning and case selection) may come to different conclusions regarding treatment.
Traditionally more than one visit is required to complete crown and bridge work, and the additional time required for the procedure can be a disadvantage; the increased benefits of such a restoration, however, will generally offset these considerations.

Famous quotes containing the words tooth and/or preparation:
“Had I but awakened from sleep
And called her name, she had heard
It may be, and had not stirred,
That now, it may be, has found
The horn’s sweet note and the tooth of the hound.”
—William Butler Yeats (1865–1939)
“It’s sad but true that if you focus your attention on housework and meal preparation and diapers, raising children does start to look like drudgery pretty quickly. On the other hand, if you see yourself as nothing less than your child’s nurturer, role model, teacher, spiritual guide, and mentor, your days take on a very different cast.”
—Joyce Maynard (20th century)
