When my dentist took my temporary crown off my eye tooth to put on my permanent crown, she broke my tooth. Will the cement hold?

Broken tooth under cemented crown
If if only a very small and non-consequential piece of the tooth chipped off then it is usually okay to go ahead and cement the new crown. However, the crown would need to be very stable on the prepared tooth with no rocking and there still must be a good height to the tooth for support of the crown.
If in in fact the tooth did break down to the gum line the long term prognosis is diminished as there is less tooth structure to actually support the crown. Not only that but the only way I know of to have enough strength for support of a crown would be by performing a palliative root canal and placing a post and buildup.
