Post-Operative Root Canal Care

What to Expect After Treatment

Root canal therapy may take 1–2 appointments to complete. After each appointment where anesthetic is used, you might find your lips, tongue, teeth, and cheek numb for several hours. Therefore, during your dental care after root canal therapy, it is advisable to avoid chewing on the treated side until the numbness has completely worn off to prevent any injury.

It is normal to experience mild to moderate discomfort for several days following treatment, especially when chewing. Some patients notice a dull ache immediately after the procedure, even if no pain existed previously. This tenderness usually improves within a few days but may persist longer in some cases. This is a typical response and not a cause for alarm.

Temporary Filling or Crown

A temporary filling or crown is placed to protect the tooth between appointments until a final restoration can be completed. 

·  It is common for a small portion of the temporary material to wear down or chip. 

·  If the entire filling falls out or a temporary crown comes off, please contact our office immediately so it can be replaced promptly.

To protect your temporary restoration:

·  Avoid chewing sticky foods (especially gum).

·  Avoid biting hard foods or objects such as ice, fingernails, or pencils.

·  If possible, chew on the opposite side of your mouth to support optimal healing as per post-operative instructions.

Pain Control & Medications

·  Take pain medication as recommended by your dentist.

·  If antibiotics are prescribed, take the full course as directed, even if symptoms improve.

·  If no prescription pain medication was given, over-the-counter options such as:

o  Ibuprofen (Motrin®, Advil®, Nuprin®)  

o  Naproxen (Aleve®, Anaprox®)  

may be used as directed.

If pain cannot be controlled with medication or if swelling develops, please contact our office.

Oral Hygiene & Rinsing

·  Continue brushing and flossing normally.

·  To help reduce discomfort and inflammation, rinse three times daily with warm salt water:

o  Dissolve 1 teaspoon of salt in a cup of warm water  

o  Gently rinse, swish, and spit.

Long-Term Care & Final Restoration

·  Radiographs are typically taken 3–4 months after treatment to confirm healing and success of the root canal.

·  In most cases, the final step includes the placement of a crown on the treated tooth.

o  A crown protects the tooth from fracture and long-term failure.

o  Unless otherwise noted, it is critical to place the crown as soon as possible. Delaying final restoration may result in fracture and possible loss of the tooth.

IMPORTANT — DO NOT:

DO NOT chew on the treated tooth while numb.

DO NOT chew hard or sticky foods on the treated side.

DO NOT bite ice, fingernails, pens, or other hard objects.

DO NOT ignore a lost temporary filling or crown.

DO NOT stop antibiotics early if prescribed.

DO NOT delay placement of the final crown.

DO NOT ignore swelling, severe pain, or changes in your bite.
