“Does a crown require a root canal?”

Hello,

No a crown does not require a root canal. The reasons for needing a crown maybe related but they are separate. If a tooth needs a crown that generally means that it is broken down in such a way that it can not be restored into a tooth without the need for a crown. Now this can be related to a root canal if the tooth is broken down in a way that it can not be restored into a tooth without a crown and the way in which it is broken down involves the center (pulp chamber) of the tooth. This would mean that the tooth has a major flaw and can not be rebuilt without causing damage to the nerve inside the pulp chamber. Hope this helps.

My best to you!

Not always, unless you are in pain after the crown is cemented or if the tooth has a cavity that is closed to the nerve or the X-rays show infection.

No usually not. A root canal treatment is only needed if the nerve inside of the tooth is damaged due to trauma or decay. The majority of teeth that I place crowns or veneers on never require root canal therapy and function perfectly normal.

Not always. Your dentist can diagnose if a root canal is necessary.

Hope this helps,

Not necessarily if the nerve is healthy. Teeth that required root canals generally require crowns however with some exceptions.

Dear Patient,

A tooth that requires a crown to restore it, may not need a root a canal. Crowns are used to restore the anatomical crown  of a tooth. They are usually recommended when a filling is no longer the appropriate restoration. If the "nerve" (pulp) of your tooth is healthy, then there is no need for a root canal. When you do have a root canal, a crown is often the best way to restore the anatomical crown of your tooth. That's because in doing the root canal, the tooth may be weakened.  
Hope this helps.

No. A root canal procedure is done when damage occurs to the nerve system inside the tooth. This is often needed if a cavity became very deep before it was repaired. Because of the amount of damage done by the cavity to the tooth and the procedure of cleaning out the inside of the tooth to remove bacteria, a crown is nearly always required on a tooth that has had a root canal procedure. Crowns are done for teeth to repair large areas of damage. This is frequently done when a tooth has very large filling and more parts of the tooth have broken away making it less predictable to repair the tooth with another even larger filling. Teeth with damage that is too large to fix with a filling alone may need a crown in order to adequately restore the tooth. This includes teeth without any need for a root canal treatment and those that require root canal treatment. Root canal treatment repairs damage to the inside of a tooth. Crown
treatment repairs damage to the outside of a tooth. A tooth can have damage to the outside of the tooth or damage to both the inside and the outside of the tooth. The treatment required all depends upon the amount of damage and the location of the damage.

Not always. You only need endodontic treatment if the nerve is Involved or has damage from decay that has irreversibly irritated it. Every situation is different.
