Yes, a root canal can develop an abscess. Here are six key points explaining how and why this might happen:

Incomplete Cleaning: If the root canal is not thoroughly cleaned and disinfected, bacteria can remain inside the tooth, leading to infection and abscess formation.

Missed Canals: Teeth sometimes have extra or hidden canals that may be overlooked during the procedure. If not treated, these canals can harbor bacteria and cause an abscess.

Leaky Crown or Filling: A poorly sealed crown or filling after a root canal can allow bacteria to enter the tooth again, resulting in reinfection and abscess.

Cracked Tooth: If the tooth develops a crack after the root canal, bacteria can enter and infect the root area, causing an abscess.

Weakened Immune Response: In people with weakened immune systems, even a well-performed root canal can occasionally fail to fully eliminate infection, leading to an abscess.

Delayed Treatment: If the tooth was already severely infected before the root canal and treatment was delayed, infection may persist or return, forming an abscess despite the procedure.

How can you tell if a tooth has gone bad under a crown that has a root canal?

If a tooth has a root canal filling you will not be able to know because the main factors of a tooth that has gone bad is sensitive to hot and cold or tender when putting any pressure on the tooth but if it has a root canal it is slightly different because the nerve is removed so you cant feel it. The tooth if it has a root canal will always go dark as the tooth is dead but this does not mean it is bad. The main sign of a bad tooth that has had root canal is an abscess under the tooth so if you feel pain when lying down that is keeping you awake at night or when leaning forward it really hurts then you have an abscess and that tooth will most probably have to be re-root canalled by a specialist or extracted! :)

Is composite core build up of root canal treatment contraindicated immediately?

Yes, a buildup is contraindicted immediately after a Root Canal Treatment. Primarily you want to make sure that root canal treatment is asymptomatic before placing any permanent restorations on the tooth. If the dentist or endodontist needs to re-enter the tooth bec. the root canal continues to give problems (pain, formation of abscess) it would be easier to remove the temporary filling. Should leave the temp. filling for 2 weeks and then if asymptomatic then do composite Buildup.
