Post-Operative Instructions
Proper aftercare helps ensure a smooth recovery. Below are our post-op guidelines for root canal treatment and endodontic surgery. If you have any concerns after your procedure, call us.
After Root Canal Treatment
Root Canal Aftercare
What’s Normal
Mild to moderate soreness in the treated tooth and surrounding area is expected for a few days, especially when biting. Your jaw may also feel stiff from keeping your mouth open during the procedure. The numbness from local anesthesia typically wears off within two to four hours. These symptoms are normal and will gradually resolve.
Pain Management
Take ibuprofen (Advil/Motrin) 600mg every 6 hours for the first 24–48 hours, even if you don’t feel pain—this controls inflammation before it builds. If ibuprofen alone isn’t enough, you may alternate with acetaminophen (Tylenol) 500mg. Take each medication as directed on the packaging. If a prescription medication was provided, take it as instructed.
Eating and Drinking
Wait until the numbness has completely worn off before eating to avoid biting your lip, cheek, or tongue. Chew on the opposite side of your mouth for the first few days. Stick to softer foods and avoid anything hard, crunchy, or sticky until your permanent restoration is placed by your general dentist.
Temporary Filling
A temporary filling has been placed in your tooth. It’s normal for a thin layer to wear down between appointments. If the filling feels like it has come out completely, or if you experience a significant change in your bite, call our office. Follow up with your general dentist within 2–4 weeks for your permanent crown or restoration—this is critical to protecting the treated tooth.
Antibiotics
If antibiotics were prescribed, take the full course as directed—even if your symptoms improve before the medication is finished.
After Endodontic Surgery
Apicoectomy Aftercare
Swelling and Bruising
Swelling is normal and typically peaks at 48–72 hours after surgery before gradually subsiding. Apply a cold compress (ice pack wrapped in a cloth) to the outside of your cheek—20 minutes on, 20 minutes off—for the first 24 hours. Some bruising in the area is also normal and will resolve on its own.
Bleeding
Minor oozing from the surgical site is expected for the first 24 hours. Avoid rinsing, spitting forcefully, or using a straw during this time. If significant bleeding occurs, apply gentle pressure with a clean gauze pad and call our office.
Diet and Activity
Eat soft, cool foods for the first 2–3 days (yogurt, smoothies, scrambled eggs, pasta). Avoid hot foods and beverages for 24 hours. Do not chew on the surgical side until cleared by your endodontist. Avoid strenuous exercise for 48–72 hours and keep your head elevated when resting.
Oral Hygiene
Do not brush or floss near the surgical site for the first 48 hours. After 48 hours, gently brush surrounding teeth. Rinse gently with warm salt water (½ teaspoon of salt in 8 ounces of warm water) 2–3 times per day starting the day after surgery. Do not use commercial mouthwash until cleared by your endodontist.
Sutures
Sutures are typically removed at your follow-up appointment, usually within 5–7 days. If a suture loosens or comes out before your appointment, this is not an emergency—just let us know at your next visit.
When to Call Our Office
Contact us if you experience: pain that worsens significantly after the first 48 hours rather than improving; swelling that increases after 72 hours or develops suddenly days after treatment; fever above 101°F; an allergic reaction to medication (rash, hives, difficulty breathing—call 911 if severe); your temporary filling comes out completely; or any symptom that concerns you.
We’re always here to help. Don’t hesitate to call even if your question seems minor—we’d rather hear from you and put your mind at ease.
