How painful is root canal treatment likely to be?
Root canal treatment uses local anesthetic to block sharp pain, although pressure and short-term tenderness afterward can occur.
What happens to the inflamed pulp during root canal treatment?
The procedure removes inflamed pulp while rubber dam isolation keeps the tooth dry as canals are cleaned and sealed.
Pre-treatment pain often comes from pulp inflammation; afterward, the ligament around the root may be tender.
What can you do if sharp pain occurs during treatment?
Tell the dentist if sharp pain breaks through, use recommended pain relief, and avoid hard foods until restoration.
When should worsening pain after treatment be reviewed?
Contact the clinic for worsening pain, swelling, fever, or a high-feeling bite.
What should you ask about pressure, pain relief, and restoration?
Ask how the tooth will be numbed, what pressure may feel like, and when restoration is planned.
