Pulp Extirpation


What is Pulp Extirpation?

A pulp extirpation is part of a root canal treatment which is performed to save a tooth where the innermost part (the pulp) has become badly infected. The pulp and bacteria inside of the pulp chamber is removed and the inside of the tooth is cleaned. In other words, root canal treatment tends the inside of the tooth. 

Our dentists at Paramount Dental Sydney have performed thousands of laser root canal treatments and have a proven track record in saving teeth from extraction. 

What does the pulp do?

The pulp contains blood vessels and keeps the tooth alive by supplying blood and nutrients to the tooth. We are able to sense pressure and temperature because of the nerves in the pulp of our teeth. The pulp also helps the tooth to fight bacteria as it contains small lymph vessels that carry white blood cells, which is why, if the pulp is badly infected, an extirpation is carried out to save the tooth. A successful root canal treatment is to remove the bacteria and prevent it from coming back into the tooth. 

Pulp Extirpation

Symptoms of a damaged root canal

  • A dull ache or severe pain in the roots and gum

  • Pain or ache when biting down

  • Swelling in the gum surrounding the infected tooth or teeth

  • A discoloured spot on the gum where puss may excrete, causing a bad taste in your mouth

Causes of a damaged root canal

There a few basic reasons for root canal damage:

  • Decayed teeth, often a result of poor oral hygiene

  • Repeated procedures to the tooth

  • Teeth that are cracked, chipped or broken which has allowed an infection to enter the pulp of the tooth

  • Other non-visible damage to the tooth caused by injury or trauma



  1. A local anaesthetic is given to numb the tooth.

  2. A hole is created in the crown of the tooth using laser, which allows the dental technician access to the root canals.

  3. The infected pulp is removed using a small instrument.

  4. The infected area is cleansed to prepare for a root canal filling.

  5. Root canal filling is put in place.

  6. Your tooth is sealed and a permanent crown is placed on the tooth.

If the infection in your tooth cannot be properly cleansed in one visit, a temporary crown will be placed on the tooth.

After several days you will need to revisit us for the procedure to be completed. During this final procedure we will:

  1. Remove the temporary crown.

  2. Cleanse the infected area a second time to clear any remaining infection and prepare for a root canal filling.

  3. The root canal filling is put in place.

  4. Your tooth is sealed and a permanent crown is placed on the tooth.

After procedure care


  • Minimise forceful chewing around the affected area.

  • Brush your teeth twice daily, but don't brush too vigorously.

  • Floss as normal however but avoid the area surrounding the crown.

  • Use a mouth rinse several times a day to keep your mouth clean.

  • If your pain worsens or the crown comes loose, please don’t delay contacting us.


  • You may experience some inflammation of the gums. If so, you can control this with over-the-counter pain relievers such as ibuprofen.


  1. Good oral hygiene is the best way to prevent decay and infection, such as brushing twice daily and flossing once a day. Check our Oral Hygiene Tips for more detailed advice and techniques.

  2. To prevent decay and infection from cracked, chipped or broken teeth be sure to book a checkup or consultation here at Paramount Dental Sydney to ensure the situation doesn’t get any worse
