Root Canal Treatment
What to Do After Getting a Root Canal
A root canal can relieve pain and help save a natural tooth, but the tooth still needs the right follow-up care. What you do after treatment matters — especially when it comes to protecting the tooth with a permanent restoration or crown.
Quick Answer
After a root canal, avoid chewing on the treated tooth until your dentist places the final restoration. Many root canal-treated teeth, especially molars and premolars, need a dental crown to protect the tooth from cracking or fracturing under chewing pressure.
At Fox Point Dental Studio, we help patients understand every step after root canal treatment, including how to manage soreness, what to eat, when to call the dentist, and why a crown may be recommended to protect the tooth long-term.
What Should I Expect After a Root Canal?
Mild soreness or tenderness after a root canal is common, especially when biting or chewing. This usually improves as the tooth and surrounding tissues calm down.
Your tooth may feel different for a few days. This does not always mean something is wrong. However, the tooth should gradually feel better, not worse.
What Should I Do Right After Treatment?
After your root canal appointment, follow your dentist’s instructions closely. In general, it is smart to:
- Avoid chewing on the treated tooth until the final restoration is placed.
- Eat softer foods for the first day or two.
- Brush and floss gently around the area.
- Take recommended medications as directed.
- Call your dentist if pain, swelling, or bite discomfort gets worse.
- Keep your follow-up appointment for the permanent filling or crown.
The root canal removes infection or inflamed tissue from inside the tooth, but the tooth still needs to be sealed and protected afterward.
Why the Tooth Often Needs a Crown After a Root Canal
This is the part many patients do not realize: a root canal-treated tooth can be more vulnerable if it is not properly restored.
A tooth that needed a root canal often already had a large cavity, old filling, crack, fracture, or significant loss of tooth structure. After treatment, the tooth may no longer have enough natural strength to handle chewing forces by itself.
A dental crown covers and protects the tooth, helping distribute biting pressure and reducing the risk that the tooth will crack or fracture.
Without a crown or proper final restoration, the tooth may break. In some cases, a fracture can go deep below the gumline or into the root, making the tooth difficult or impossible to save.
Does Every Root Canal Tooth Need a Crown?
Not every tooth is exactly the same. Whether you need a crown depends on the location of the tooth, how much natural tooth structure remains, your bite, whether you grind or clench, and how much chewing force the tooth receives.
Back teeth, such as molars and premolars, usually take heavy chewing forces and commonly need crowns after root canal treatment. Front teeth may not always need crowns if enough healthy tooth structure remains, but they still need a strong permanent restoration.
Your dentist will evaluate the tooth and explain whether a crown, permanent filling, build-up, post, or another restoration is the best option.
What Can I Eat After a Root Canal?
Until the tooth has its final restoration, stay with softer foods and avoid chewing directly on that tooth.
- Good options: eggs, pasta, soup, yogurt, smoothies, mashed potatoes, soft rice, and soft cooked vegetables.
- Avoid: hard nuts, ice, crunchy chips, sticky candy, hard bread, tough meats, and chewing gum.
Once the tooth is restored with the final filling or crown and your bite feels comfortable, you can usually return to normal chewing based on your dentist’s instructions.
How Long Should I Wait to Get the Crown?
Do not wait longer than recommended. The temporary filling or temporary restoration is not meant to protect the tooth forever.
If a crown is recommended, delaying it can increase the risk of leakage, sensitivity, decay, or fracture. The longer a weakened tooth is left unprotected, the more likely it may be to crack under chewing pressure.
When Should I Call the Dentist After a Root Canal?
Call the office if you notice:
- Pain that gets worse instead of better
- Swelling in the gums, face, or jaw
- A temporary filling that feels loose or falls out
- A high bite or pain when biting down
- Fever or feeling sick
- Cracking, breaking, or sharp edges on the tooth
If something does not feel right, it is better to call early. Small issues are usually easier to manage before they become bigger problems.

Root Canal Done? Protect the Tooth Next
A root canal can help save your natural tooth, but it is only part of the process. The final restoration is what helps protect the tooth so it can function properly.
If your dentist recommended a crown after root canal treatment, it is usually because the tooth needs added strength and protection. Skipping or delaying the crown may put the tooth at risk for fracture.
Frequently Asked Questions
Why does my tooth need a crown after a root canal?
Many root canal-treated teeth have already lost strength because of decay, cracks, fractures, or large fillings. A crown helps protect the remaining tooth structure and reduces the chance of the tooth breaking under chewing pressure.
Can I chew before getting the crown?
It is best to avoid chewing on the treated tooth until the final restoration is placed. Chewing too soon can increase the risk of breaking the tooth or damaging the temporary restoration.
What happens if I do not get the crown?
The tooth may be more likely to crack, fracture, leak, or develop new decay. If a fracture extends too deep, the tooth may not be restorable.
Is soreness normal after a root canal?
Mild soreness can be normal for a few days. Pain that worsens, swelling, fever, or pain when biting should be evaluated by a dentist.
