Post-Operative Instructions for Root Canal Treatment

Root canal therapy removes infection from inside the tooth. Proper care after treatment protects the tooth and supports healing.

What to Expect

• Mild to moderate tenderness for several days is normal.
• Sensitivity when biting or touching the tooth may occur for 3 to 5 days.
• Jaw soreness from keeping the mouth open is common.
• If treatment was completed in stages, a temporary filling or medicated dressing may be present.

Symptoms should gradually improve.

Pain and Medications

• Begin pain relief before the numbness wears off.
• Use ibuprofen or paracetamol as directed unless otherwise advised.
• Take prescribed antibiotics exactly as instructed and complete the full course.
• Mild discomfort when biting is normal; increasing pain is not.

Eating and Function

• Do not eat until numbness has fully worn off.
• Avoid chewing on the treated tooth until a permanent restoration is placed.
• If a temporary filling or crown is present:
  • Avoid sticky or hard foods.
  • Chew on the opposite side.
  • Avoid excessive pressure on the tooth.
• The tooth is more fragile until properly restored.

Oral Hygiene

• Continue brushing and flossing normally.
• Clean gently around the treated tooth.
• Do not avoid brushing the area.
• Maintaining good hygiene prevents reinfection.

Final Restoration

• Return for your final crown or permanent restoration within the recommended timeframe (usually 1 to 3 weeks).
• Delaying final restoration increases the risk of fracture or reinfection.
• Back teeth that have had root canal treatment typically require a crown for protection.
