  When the nerve of your tooth becomes infected, a successful root canal treatment 
  lets you keep the tooth rather than having to pull it out. Keeping your tooth helps to 
  prevent your other teeth from drifting out of line and causing jaw problems. Saving 
  a natural tooth avoids having to replace it with an artificial tooth.
  Root canal treatment is the process of removing infected, injured or dead pulp 
  from your tooth. The space inside the hard layers of each tooth is called the root 
  canal system. This system is filled with soft dental pulp made up of nerves and 
  blood vessels that help your tooth grow and develop.
  When bacteria (germs) enter your tooth through deep cavities, cracks or flawed 
  fillings, your tooth can become abscessed. An abscessed tooth is a tooth an 
  infection in the pulp. If pulp becomes infected, it needs to be removed. An 
  abscessed tooth may cause pain and/or swelling. Your dentist in Mississauga
  Churchill Glen Dental may notice the infection from a dental x-ray or from 
  other changes with the tooth. If left untreated, an abscessed tooth can cause 
  serious oral health problems. Contrary to common belief, root canal treatment is no
  long painful due to the advance in the technology and safe technique used by our
  dentists.
