A root canal can take many appointments because the dentist will have to open up the tooth and removed the pulp and open up the canals. This can take several appointments depending on how severe or complicated the case is. Even though this can take one appointment, the second step of a root canal is getting a crown to help restore the root canal. This CANNOT be done the same day because the dentist will need to take an impression of your teeth after the root canal treatment and they will have to send your impressions to a lab that will create you a new crown that will be placed on top of the root canal.
Thank you for your question.
