IDK
I had a root canal and the dentist put fillings after taking all the "stuff" out.
A root canal is a procedure to deaden the nerve in the tooth so that you dont have pain. The dentist removes the pulp and rot debris inside the tooth, then uses small files to loosen the nerves in the tooth legs, and then fills the tooth with a hardening filler. Either leaves it that way or you can have a crown put over that.
A root canal involves taking out the nerve or pulp from the root, as well as removing any infection. The root is then filled with a rubbery substance called gutta percha. At this time the inside of the crown of the tooth can be filled with a cotton pellet and a temporary filling. Finally, the crown of the tooth will need to be permanently restored with a filling or a cap.
The root canal contains the pulp or blood supply of your tooth. The ADA website explains the procedure:
"
First, an opening is made through the crown of the tooth.
An opening is made through the crown of the tooth into the pulp chamber.
The pulp is then removed. The root canal(s) is cleaned and shaped to a form that can be filled.
The pulp is removed, and the root canals are cleaned, enlarged and shaped.
Medications may be put in the pulp chamber and root canal(s) to help get rid of germs and prevent infection.
A temporary filling will be placed in the crown opening to protect the tooth between dental visits. Your dentist may leave the tooth open for a few days to drain. You might also be given medicine to help control infection that may have spread beyond the tooth.
The pulp chamber and root canals are filled and sealed.
The temporary filling is removed and the pulp chamber and root canal(s) are cleaned and filled.
In the final step, a gold or porcelain crown is usually placed over the tooth. If an endodontist performs the treatment, he or she will recommend that you return to your family dentist for this final step.
The crown of the tooth is then restored."

As you can see, there are several steps to complete a root canal treatment. There can be cotton, medication, or a temporary filling in the space during treatment. After the root canal therapy is completed the final filling is placed in the canal. The opening in the main part of the tooth still has to be filled (usually by the general dentist) and then a crown to prevent future breakage ( a tooth without blood supply gets brittle over time).

It's a lot of stuff going in and out of your tooth - but very worth it
Vote for pretty toes - good answer. Here's an old answer that I keep recycling, so don't vote for me...

A root canal treatment is "basically" the act of taking out the contents from the center of the root, all the way to the tippy end, and then sealing the hollow space with a filling material. Many people say that they "had the root removed" from a tooth, but root canal treatment treats the CANAL in the center of the tooth.

Usually, it is required when the tissue inside the center of the tooth (ie: in the root canal) is diseased or dead. This is usually the result of an infection caused by tooth decay that has gone "all the way to the nerve." The idea here is to eliminate the infection by removing the tissue. The next goal is to smooth out the inside of the canal(s) so that a filling material can pass freely to the end of the tooth to seal it off. Once it is sealed off, it is no longer a source of infection to your body. Your natural immune system will continue to fight off any infection that may have entered the bone and eventually your body will heal. Some people need antibiotics to help in this fight, but they are not always necessary.

In back teeth, it is generally recommended to have a crown placed over the tooth to protect it from breaking, as teeth that have had root canal treatment tend to dry out somewhat and become more brittle and susceptible to breaking. Front teeth are often strong enough to go without a crown, but sometimes they need a crown, too.

Yeah, it can hurt, maybe 1 out of 10 times. That 1 guy where it hurts probably waited until the tooth was already really killing him before he went for treatment. I tell my patients that root canal treatments are like teenagers. 9 out of 10 are no problem at all, but you always hear about the bad ones.
Ok, you've been told what a root canal is by a few people. If you are having "cotton stuff" coming out of that tooth, that means that your temporary filling has fallen out. What happens is, after the root canal they will place a few cotton pellets where the nerve chamber used to be (this is the area right before it goes down to the roots of the tooth) and then they place a temporary filling. What you need to do is call your dentist and let them know that your temporary filling has fallen out. They will either get you in to 1) put a temp. filling in, 2) Put a permanent filling in or 3) prep this tooth for a crown. Usually, all teeth that have had root canals need a crown because it will break if it is not done. Please call your dentist tomorrow and let them know.
