Recovery Tips: What to Eat After Root Canal Therapy

By Dr. Jane Collins | December 19, 2025

Congratulations! The hard part is over. You've had your root canal, and your tooth is on the road to recovery. While you can usually return to work or school immediately, your mouth will need a little TLC for the next few days.

The anesthesia will leave your mouth numb for a few hours, and the tooth may be tender once it wears off. Knowing what to eat (and what to avoid) is key to a smooth, comfortable recovery.

The Golden Rule: Wait for the Numbness to Fade

Do not eat anything until the numbness in your tongue and lips has completely worn off. It is incredibly easy to accidentally bite your cheek or tongue severely when you can't feel them. Stick to liquids (like lukewarm smoothies) if you are hungry immediately after the appointment.

What to Eat: The Soft Food Menu

For the first 24-48 hours, treat your mouth gently. Stick to foods that require minimal chewing:

Cool foods: Yogurt, smoothies (skip the straw), applesauce, pudding, and ice cream are soothing.
Warm (not hot) foods: Mashed potatoes, scrambled eggs, oatmeal, soft pasta, and lukewarm soups.
Protein: Soft fish, hummus, or protein shakes to keep your energy up.

Foods to Avoid

Protect your temporary filling! Until your permanent crown is placed, your tooth is fragile. Avoid:

Crunchy foods: Nuts, chips, carrots, and ice.
Sticky foods: Gum, caramel, taffy, and gummy candies (these can pull out your temporary filling).
Chewy foods: Steak or crusty bread.
Very hot liquids: Coffee or tea that is too hot can increase sensitivity or dissolve temporary cement.

Managing Discomfort

It is normal for the tooth to feel tender or 'bruised' for a few days. Your jaw may also be sore from keeping your mouth open. Over-the-counter medications like ibuprofen (Advil) or acetaminophen (Tylenol) usually work very well. Try to chew on the opposite side of your mouth until the tenderness subsides.
