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.
