Post-Operative Instructions – Root Canal Preparation Appointment

A root canal preparation appointment involves cleaning and disinfecting the inside of your tooth to remove infection and protect the surrounding bone. This may be completed over one or more visits.

It is normal to experience some discomfort following treatment.

The root canal preparation appointment is the first of two root canal appointments.

What to Expect

  • Mild to moderate tenderness ranging from a few days to a couple of weeks.
  • Sensitivity when biting or chewing
  • Tenderness around the gum near the treated tooth
  • Temporary numbness for 2–4 hours after treatment

Discomfort should gradually improve over several days.

 

Pain Management

  • Take pain relief as recommended by your dentist.
  • If suitable for you, Ibuprofen (Nurofen) and/or Paracetamol (Panadol) may be taken as directed on the packaging.
  • Do not exceed the recommended dosage.
  • Avoid aspirin as it may increase bleeding.

If antibiotics were prescribed, please complete the full course.

 

Eating & Drinking

  • Do not eat until the numbness has completely worn off.
  • Avoid chewing on the treated tooth until treatment is completed.
  • Choose softer foods for the first few days.
  • Avoid very hot, cold, or hard foods if sensitivity occurs.

 

Temporary Filling Care (If Placed)

A temporary filling may be placed between appointments.

  • Avoid chewing hard or sticky foods on that side.
  • If the filling feels loose or falls out, contact our practice promptly.
  • It is important to attend your next scheduled appointment to prevent reinfection.

 

Oral Hygiene

  • Continue brushing and flossing as normal.
  • Be gentle around the treated area if it feels tender.

 

When to Contact Us

Please contact our practice if you experience:

  • Increasing swelling of the face or gums
  • Severe or worsening pain not relieved by medication
  • Fever or feeling unwell
  • Loss of the temporary filling
  • Difficulty swallowing or breathing (seek urgent medical care)

 

Important

Root canal treatment is not complete until the tooth is permanently restored, often with a crown. Delaying restoration increases the risk of fracture or reinfection.
