When Root Canal Treatment May Be Considered
Deep decay, a crack, trauma or a leaking restoration can inflame or infect the dental pulp. Symptoms vary and some teeth have few symptoms.
- Persistent or severe toothache
- Lingering sensitivity to hot or cold
- Pain when biting or chewing
- Swelling, a gum pimple or a bad taste
- A darkened tooth after trauma
- A deep cavity or crack close to the pulp
Examination and Diagnosis
The dentist will ask about your symptoms and medical history, examine the tooth and gums, and may perform bite, sensitivity or vitality tests. Dental X-rays may be recommended to assess the roots and surrounding bone. The assessment also considers whether the tooth can be predictably restored and whether referral is appropriate.
Root Canal Treatment Stages
Treatment commonly takes place over one or more visits, depending on the tooth and clinical findings.
- Local anaesthetic and isolation of the tooth
- Access to the pulp space and removal of inflamed or infected tissue
- Cleaning, shaping and disinfecting the canals
- Medication or a temporary filling between visits where needed
- Filling and sealing the canals after the tooth is ready
- Planning the final restoration to protect the tooth
Temporary and Final Restoration
A temporary filling may protect the tooth between visits. After root canal treatment, the tooth still needs a durable final restoration. A filling may be suitable in some cases; a crown or other cuspal-coverage restoration is often discussed for a weakened back tooth. Avoid hard chewing on a temporary restoration and return promptly if it breaks or comes out.
Alternatives and Referral
Alternatives may include monitoring in limited situations, removing the tooth, or seeking an endodontic opinion. An extracted tooth may later be replaced with a bridge, denture or implant where suitable. Complex anatomy, previous root canal treatment or other risk factors may require referral. Your dentist will explain why a particular pathway is recommended.
Risks, Retreatment and Outcomes
Root canal treatment aims to retain the tooth, but success cannot be guaranteed. Risks can include persistent infection or pain, instrument separation, perforation, missed anatomy, tooth fracture, discolouration or the need for further treatment. Retreatment, surgery, specialist care or extraction may sometimes be required.
Aftercare and Warning Signs
Some tenderness can occur after treatment. Follow the dentist’s instructions, keep the area clean and attend the planned restoration and review visits. Contact the clinic promptly for worsening pain, swelling, fever, a lost temporary filling or a change in your bite. If swelling is rapidly spreading or affects breathing or swallowing, seek urgent medical care or call triple zero (000).
Fees, Health Funds and Booking
The number of visits and fee depend on the tooth, complexity, imaging and final restoration. The clinic can provide an itemised estimate after assessment. Health fund rebates vary by policy, limits and item numbers, so confirm benefits directly with your fund. Call 03 9894 3039 or book online for an assessment.
