Root Canal Aftercare: Your Complete Recovery Guide
You have just taken a major step toward saving your natural smile. Root canal therapy is a highly effective procedure designed to eliminate infection and preserve a tooth that might otherwise need extraction. While the treatment itself is now behind you, the healing process is just beginning. Proper aftercare is essential to ensure your tooth heals correctly and remains healthy for years to come.
At Horizon Dental, we want your recovery to be as smooth and comfortable as possible. This comprehensive guide will walk you through exactly what to expect in the hours and days following your treatment, how to manage any discomfort, and how to protect your tooth until your final restoration is placed.

Immediate Steps After Your Appointment
Root canal therapy often requires the use of local anesthesia to ensure you remain comfortable throughout the procedure. As you leave our office, it is likely that your lips, teeth, and tongue will still feel numb. This sensation can last for several hours.
During this time, it is critical to be mindful of your mouth. Because you cannot feel pain or pressure in the anesthetized area, it is very easy to accidentally bite your cheek, lip, or tongue, potentially causing significant injury. For this reason, we strongly advise you to avoid chewing any food until the numbness has completely worn off.
If you are hungry immediately after your appointment, stick to liquids or very soft foods like yogurt or smoothies that don’t require chewing. However, be careful with temperature—you may not be able to feel if something is too hot, which could lead to accidental burns.
Managing Discomfort and Tenderness
One of the most common questions patients ask is, “Will it hurt afterwards?” It is completely normal to experience some discomfort for several days after a root canal appointment. Even if you were not in pain prior to the procedure, the manipulation of the tooth and surrounding tissues can cause inflammation.
It is not uncommon for the treated tooth to feel tender or even exhibit a dull ache immediately after the anesthesia wears off. This tenderness is a normal part of the body’s healing response and is generally no cause for alarm. This discomfort typically subsides within a few days, though in some cases, mild sensitivity can linger for a couple of weeks.
Strategies for Pain Relief
To keep yourself comfortable during recovery, we recommend the following strategies:
- Follow Prescription Instructions: If your dentist has prescribed specific pain medication, take it exactly as directed.
- Over-the-Counter Options: If no prescription was given, over-the-counter anti-inflammatory medications are highly effective. We recommend taking ibuprofen (Motrin, Advil, Nuprin) or naproxen (Aleve, Anaprox). These medications do a great job of reducing both pain and inflammation in the jaw.
- Finish Your Antibiotics: If antibiotics were prescribed to fight infection, it is critical that you continue to take them for the full indicated length of time. Do not stop taking them just because your symptoms disappear. Finishing the full course ensures the infection is completely eradicated and prevents it from returning.
If you experience severe pain that cannot be managed with these medications, or if you notice visible swelling inside or outside your mouth, please call our office immediately.
Caring for Your Temporary Restoration
Root canal therapy often takes one to two appointments to complete. Between visits, or while you await the fabrication of your permanent crown, your dentist will place a temporary filling or crown to seal and protect the tooth.
Because this restoration is temporary, it is not as durable as a permanent tooth. It is designed to be easily removed by your dentist, which means it requires gentle care to stay in place. It is common—and usually not a problem—for a small portion of the temporary filling to wear away or break off during normal use. However, if the entire filling falls out or if a temporary crown comes off completely, please contact our office so it can be replaced. An exposed tooth is susceptible to reinfection and fracture.
Protecting Your Temporary Filling
To ensure your temporary restoration stays in place and protects your tooth effectively:
- Avoid Sticky Foods: Gum, taffy, caramel, and other sticky candies can pull the temporary filling right out of the tooth.
- Avoid Hard Foods: Do not bite down on hard substances like ice, nuts, hard candy, or non-food items like fingernails and pencils. The tooth is hollowed out and brittle right now; biting hard things can cause it to crack vertically.
- Chew on the Opposite Side: Whenever possible, chew your food on the side of your mouth opposite the treated tooth. This minimizes pressure and reduces the risk of damaging the temporary seal.
Oral Hygiene for Faster Healing
Keeping your mouth clean is vital for preventing infection during the healing process. You should continue to brush and floss your teeth normally. However, be gentle around the treated tooth.
When flossing near a temporary filling or crown, you need to adjust your technique. Slide the floss down between the teeth as usual to clean the area. However, when removing the floss, do not pull it back up through the contact point. Pulling up can catch the edge of the temporary and pop it off. Instead, release one end of the floss and pull it out through the side.
To further reduce pain and promote healing, we recommend rinsing your mouth three times a day with warm salt water. Dissolve one teaspoon of salt in a cup of warm water, then gently rinse, swish, and spit. This simple remedy helps soothe gum tissue and keeps the area clean without using harsh chemicals.
The Importance of the Permanent Crown
Usually, the final step after root canal treatment is the placement of a permanent crown on the tooth. While the root canal removes the infection, it also leaves the remaining tooth structure weaker and more brittle than a vital tooth because the blood supply has been removed. A crown acts like a protective helmet, covering the entire tooth to prevent it from breaking in the future.
Unless otherwise noted by your dentist, it is critical to have a crown placed on your root canal-treated tooth as soon as possible. Delaying this final restoration puts the tooth at significant risk. Without the reinforcement of a crown, the tooth is prone to fracture under the pressure of chewing. If a vertical fracture occurs, the tooth often cannot be saved and must be extracted, meaning the effort to save it via root canal would be lost.
