Root Canal Diet: What to Eat (And Avoid) After Treatment

After a root canal, your mouth needs some TLC—and that includes being careful about what you eat. The good news is that dietary restrictions are temporary and mostly common sense.

Here's your complete guide to eating after a root canal, from the first hour to full recovery.

The First Few Hours: Wait Before Eating

Wait until numbness wears off
This is the most important rule. Your mouth will be numb for 2-4 hours after the procedure. Eating while numb is risky because:

You can't feel if you're biting your cheek or tongue

Hot foods can burn without you noticing

You may chew unevenly and damage the temporary filling

When it's safe to eat:

Wait until you can feel your lips and tongue normally

Test by gently pressing on tissues

Usually 2-4 hours post-procedure

Days 1-3: Soft Foods Only

During initial healing, stick to soft, easy-to-chew foods:

Good options:

Yogurt and smoothies

Mashed potatoes

Scrambled eggs

Soup (not too hot)

Pasta and soft noodles

Oatmeal

Bananas and soft fruits

Applesauce

Cottage cheese

Protein shakes

Why soft foods:

Less pressure on the treated tooth

Less risk of damaging the temporary filling

Easier on tender gums

Reduces inflammation

Foods to Avoid After Root Canal

Stay away from these until you're fully healed:

Hard foods (risk of breaking filling):

Nuts

Hard candy

Popcorn

Raw carrots or apples

Crusty bread

Sticky foods (can pull out filling):

Caramel

Taffy

Chewing gum

Gummy candies

Very hot or cold (causes sensitivity):

Ice cream (at first)

Hot coffee or soup (let it cool)

Crunchy or chewy:

Chips

Tough meats

Bagels

Jerky

Eating on the Right Side

Chew on the opposite side
For the first several days (and until you get your permanent crown), chew primarily on the side opposite your treated tooth.

Why this matters:

Protects the temporary filling

Reduces pressure on healing tooth

Prevents sensitivity

Avoids potential damage

When you can chew normally:

Light chewing after 3-5 days

Normal chewing after permanent crown is placed

Follow your dentist's specific guidance

After Your Permanent Crown

Once you have your permanent restoration, you can return to normal eating:

Immediately after crown placement:

Wait for any numbness to wear off

Start with softer foods for 24 hours

Avoid very sticky foods for 48 hours (cement needs to set)

Long-term:

No permanent dietary restrictions

Treat the crowned tooth like any natural tooth

Still good to avoid extremely hard foods (can damage crowns)

Normal diet otherwise

Key Takeaways

Eating after a root canal is straightforward: wait for numbness to fade, stick to soft foods for a few days, and avoid anything that could damage your temporary filling. Once you get your permanent crown, you can eat normally again.

The temporary restrictions are worth it—protecting your treated tooth during healing helps ensure the best long-term outcome.
