What to Eat After a Root Canal

After a root canal, the treated tooth and surrounding gum can be tender for a few days, and the tooth is usually protected only by a temporary filling until the final crown is placed. Choosing the right foods helps you stay comfortable and avoids damaging the tooth.

When can you eat after a root canal?

Wait until the numbness has completely worn off — usually two to four hours — before eating. Eating while numb makes it easy to bite your cheek, tongue or lip without noticing. Start with soft, lukewarm foods and chew on the opposite side.

Best foods to eat after a root canal

• Yogurt, smoothies (without seeds) and milkshakes
• Mashed potatoes, sweet potatoes and cauliflower mash
• Scrambled eggs and omelets
• Oatmeal, cream of wheat and soft cereals soaked in milk
• Soups and broths, served warm rather than hot
• Pasta, macaroni and cheese and soft rice
• Soft fish such as salmon, and shredded chicken
• Bananas, applesauce and ripe avocado
• Cottage cheese, hummus and soft tofu
• Pudding and ice cream (if cold doesn't bother you)

Foods to avoid

• Hard foods — nuts, hard candy, ice, crusty bread and raw carrots can crack a weakened tooth.
• Sticky foods — caramel, taffy and chewing gum can pull out the temporary filling.
• Chewy foods — steak, bagels and jerky put heavy force on the tooth.
• Very hot or very cold foods if the tooth is sensitive.
• Crunchy snacks — chips and popcorn can lodge under the gum.
• Alcohol and smoking — they can slow healing and interact with pain medication.

How long to follow a soft diet

Most people return to their normal diet within a few days as tenderness fades — but keep avoiding hard or sticky foods on the treated tooth until your permanent crown or filling is placed. A root-canal-treated tooth, especially a molar, is more brittle and can fracture before it's protected. Learn more about root canal recovery time.

Tips for comfortable eating

• Chew on the opposite side of your mouth.
• Cut food into small pieces.
• Keep brushing and flossing gently around the tooth.
• Take pain relievers as directed by your dentist.
• Call the office if your bite feels high or the temporary filling feels loose.

When to call your dentist

Mild tenderness for a few days is normal. Call if pain gets worse instead of better, swelling appears, the temporary filling falls out or you notice a bad taste. These can be signs of infection after a root canal.
