Root canal is a treatment to repair and save a badly damaged or infected tooth instead of removing it. The term "root canal" comes from cleaning of the canals inside a tooth's root. Decades ago, root canal treatments often were painful.

==============================================
Do I need a post and crown after root canal?
The general rule of thumb is that a dental crown will need to be placed over a tooth that has just received a root canal if the tooth is a premolar, a molar or one of the back grinding teeth. These teeth need to be kept strong as they are used continuously when eating throughout the day.

Can you get a crown without a post?
As general rules of thumb: If more than half of a tooth's original crown portion (the part of the tooth normally visible above the gum line) has been lost, a post is needed to assist with anchoring the core to the tooth. If more than half of the tooth's crown still remains, a core by itself will probably suffice.Dec 23, 2021

Do all root canals require a post?
In summary: Yes, posts are often needed, and there are many clinical factors related to whether or not they should be used, in addition to just how much tooth structure is remaining. Clinical judgment is still critical in deciding whether or not to use posts.Oct 31, 2012


How deep should a dental post be?
At a bare minimum, the post should extend at least a distance equal to the height of the crown being placed. Most ideally, it will extend around 2/3rds the length of the root. However, 3/16ths of an inch or so of gutta percha needs to be left undisturbed at the root's tip to maintain an adequate endodontic seal.Dec 23, 2021
