Ask the Dentist: A Helpful Guide to Root Canal Treatment


Root canal treatment is one of the dental operations which is feared by many people. However, it cannot be avoided if prescribed by the dentist. If performed correctly, this operation will not feel pain. So, it is important to go for the right root canal treatment in Oshawa.

However, many people are still not aware of this operation and why one would need it. Here, you will know everything about the root canal operation, when it is required and what the outcome of this dental therapy is.

What happens if you don’t take care of your teeth?

If you don’t care for the tooth, it could cause you much pain and suffering. If you don’t get treatment, the blood vessels and nerves inside the tooth will get badly infected, which will cause pus and abscesses to form. An abscess is a pus-filled swelling that forms when infection builds up at the end of the root canal. The abscess may be so bad that it causes edema in the face, eyes, or neck. There are times when you may have to go to the hospital right away. If you don’t treat the tooth, you might also lose bone around the roots of the tooth.

Steps in Root Canal Treatment in Oshawa?

Treatment for a root canal is done in three steps throughout one to three visits.

  1. Cleaning the inside of the teeth

First, the dentist takes everything out of the root canal. Then, while the patient gets a local anaesthetic, the dentist makes a tiny hole in the tooth’s surface and uses fine files to remove the damaged and dead pulp tissue.

  1. Putting pulp in the chamber

The hollow area is then cleaned, shaped, and free of germs using small files and irrigation solutions. The canals are then completely sealed by filling the tooth with a rubber-like substance stuck in place with glue.

After root canal therapy, the tooth is dead. After the nerve tissue and infection are taken out, and the tooth is cleaned, the patient will no longer feel pain in that tooth.

  1. Giving a tooth a crown

But the tooth is now more likely to break than before. If a tooth doesn’t have pulp, it must get its nutrients from the ligament that holds it to the bone. This is enough, but over time the tooth will become more fragile and need a crown or filling to protect it.

The person shouldn’t bite down on the tooth until the crown or filling is done. After a crown or filling has been put on a tooth, it can be used like any other tooth. However, if the canals are curved, there are a lot of them, or there are serious infections, the treatment may take an extra one or two visits.


When you go to the dentist for root canal treatment in Oshawa, often because you have a toothache, they tell you your tooth needs root canal treatment. Why? The goal of root canal therapy is to eliminate the infection caused by bacteria inside the tooth and make it less likely that the infection will return. Even though root canal treatment is a long and hard process, each step is done to reduce the chance of infection coming back.
