Post-Op Instructions


Root Canal Therapy may take two or more appointments to complete. A temporary filling or crown has been put in place to protect your tooth between appointments. After each appointment when anesthetic has been used, your lips, teeth and tongue may be numb for several hours. Avoid any chewing until the numbness has completely worn off.

Between appointments it is common (and not a problem) for a small portion of your temporary filling to wear away or break off. If the entire filling falls out, or if a temporary crown comes off, call the office so it can be replaced.

It’s normal to experience some discomfort for several days after a root canal appointment, especially when chewing. To control discomfort, take pain medication as recommended. If antibiotics were prescribed, continue to take them for the indicated length of time, even if all symptoms and signs of infection are gone.

To further reduce pain and swelling, rinse three times a day with warm salt water; dissolve a teaspoon of salt in a cup of warm water, then rinse, swish, and spit.

To protect the tooth and help keep your temporary in place:

  • Avoid chewing sticky foods (especially gum).
  • Avoid hard foods and hard substances, such as ice, fingernails, and pencils.
  • If possible, chew only on the opposite side of your mouth.

Occasionally an infection can develop 48 to 72 hours after a root canal procedure. If you experience swelling or pain or there are complications with your medicines, please call the office at 781-237-3031.

It is important to continue to practice good oral hygiene, including brushing, flossing and regular checkups and cleanings. The last step after root canal treatment is the placement of a crown on the tooth. A crown covers and protects the tooth from breaking in the future. This restoration should be scheduled as soon as possible. If your bite feels uneven, you have persistent pain, or you have any questions or concerns, please call the office.

Post Surgical Instructions—Dr. Khankari

After leaving the office, relax for the remainder of the day. Keep your head elevated and sleep with 2-3 pillows the first night after surgery. Avoid strenuous activity for several days. Sunbathing should be avoided for two days after surgery to avoid swelling and fatigue. Avoid smoking as it will delay healing. Also, avoid alcoholic beverages while taking the prescribed medications. 

For the first few days, soft food can be eaten. Try to avoid spicy, crusty, acidic or seedy types of food. Chewing should be done on the side opposite the surgical site. Although it is necessary to maintain a relatively normal diet throughout the course of healing, it may be necessary to eat soft foods for several days. Do not use a straw, as suction can cause bleeding. 

Swelling/discomfort can be minimized by the use of ice/cold packs in 15-minute intervals for 24-48 hours after surgery. Some swelling may be present the day after surgery and usually peaks at 48 to 72 hours. This should disappear after 6 to 7 days. Cool/cold liquids and soft foods only for 24 hours after surgery. Discomfort is expected and is usually controlled with the medications prescribed. The discomfort usually will disappear shortly after the sutures have been removed and the dressing changed. You may experience a feeling of slight weakness during the first 48 hours. 

There should be minimal bleeding after the surgery is completed. There may be a red discoloration of the saliva for several hours. If there is considerable bleeding, apply uninterrupted pressure to the inside of the mouth for 20-30 minutes. Use moist gauze or a moist tea bag to apply pressure over the surgical area. If there is no change in the amount of bleeding contact your doctor. 

If a dressing has been placed over the surgical site, avoid the area as much as possible. The dressing is primarily for your comfort and to protect the surgical area during healing. Should the dressing or a portion of the dressing become loose or come off and there is no discomfort, healing will proceed provided the area is cleaned with the prescribed rinses. 

It is important to maintain a normal level of oral hygiene in the non-operated areas by brushing and flossing. Where there is dressing, brush the tops of teeth lightly and apply prescribed rinses with cotton swab or by holding the rinse in place for 30-60 seconds. Warm salt water rinses can be used in the same manner starting 36 hours after surgery and will expedite healing. 

Please follow the instructions for any medication prescribed. If adverse reactions to those medications occur, such as nausea, vomiting, allergic reactions please discontinue the medication and contact your doctor. To avoid medication side effects, such as upset stomach, take medication with food.
