What are the signs and symptoms of a root canal problem?
When a tooth dies due to trauma or decay, it leads to a root canal infection. An extremely painful tooth and swelling of the gums around a tooth are common symptoms of a root canal problem. A sinus tract with pus leaking out may be develop close to the root of the tooth. The tooth may also discolour and turn gray.
How is root canal treatment done?
The dentist will first remove all decay from the tooth. He will then access the root canal of the tooth and remove all infected tissue from the root canal. Using antibacterial solutions and mechanical files, he will disinfect the root canal. A medicament may be placed to further ensure disinfection of the root canal. Lastly, an inert material will be used to fill up the root canal to seal it off and prevent re-infection.
Is there anything needed for the tooth after the root canal treatment?
A tooth that requires root canal treatment is often compromised and may be weaker than a healthy tooth. As such, crowns are recommended for root canal treated posterior teeth to prevent them from cracking. Crowns may not be needed for a root canal treated anterior teeth, but as they tend to discolour, internal bleaching to lighten the tooth shade or other aesthetic treatments may be indicated.
