Medical Forum / General / Dentistry / April 2008Crowned teeth need root canals?
Over time (say 20-30 years) do most crowned molars eventually end up needing root canals? Thanks. About 4%  Signature/ Amatus / > Over time (say 20-30 years) do most crowned molars eventually end up > needing root canals? Thanks. Depends on the condition of the tooth when it received the crown.

A crown placed on such a tooth will generally lead to RCT more often than a crown made to replace a fractured cusp. This is of course valid for any type of restoration; the deeper you have to drill the more likely to stir things up. The 4% statistic quoted by Amatus should be accurate, but it probably represents an average over all crowns made for any clinical indication.

Regards, George > About 4% Thanks - is that from your observation from your practice, or are they industry statistics? Statistics I read in a paper a few years back. My percentages have always been less than that figure. Especially since switching to machine milled porcelain.
