Root Canal Therapy
Root Canal Therapy
Symptoms of tooth pulp damage or disease
A diseased tooth pulp may cause inflammation or infection. The symptoms of a damaged or diseased tooth pulp may include:
- unprovoked or spontaneous pain
- sensitivity to hot and cold drinks and foods
- pain when biting or chewing
- loosening of the tooth
- swelling of the gum near the affected tooth
- oozing of pus surrounding the affected tooth
- facial swelling
Sometimes, tooth pulp may become damaged or diseased without any symptoms. In these cases, the problem is usually diagnosed by special tests or x-rays during a dental check-up or treatment for other dental concerns.




Who needs to get a root canal therapy?
Root canal treatment is needed when dental X-rays show that the pulp has been damaged by a bacterial infection.
The pulp may become inflamed if it’s infected by bacteria, allowing the bacteria to multiply and spread.
The symptoms of a pulp infection include:
- pain when eating or drinking hot or cold food and drink
- pain when biting or chewing
- a loose tooth
As the infection progresses, these symptoms often disappear as the pulp dies.
Your tooth may appear to have healed temporarily, but the infection could continue spreading through the root canal system if untreated.
You may eventually experience further symptoms, such as:
- pain when biting or chewing returning
- swelling of the gum near the affected tooth
- pus oozing from the affected tooth
- a swollen cheek or jaw
- the tooth becoming a darker colour
It’s important to see your dentist if you develop toothache. If your tooth is infected, the pulp cannot heal by itself. Leaving the infected tooth untreated may worsen the condition.
Root canal treatment is most effective when performed before the infection becomes established.

My experience at K Family Dental was fantastic. I hadn't been to the dentist for some time and wasn't sure what to expect. Dr Chen was very friendly and took... Read More the time to explain to me why certain things were important (there was a lot I learnt during the visit). I also thought he was very thorough and was genuinely interested in my well-being. I'd definitely recommend his practice to others.
