If you’ve had or will have a root canal, you’re likely worried about pain afterward. Root canals treat tooth infections, but some post - procedure discomfort is normal. Here’s what you need to know.​

Why Does Pain Happen After a Root Canal?​

During a root canal, dentists clean your tooth and remove damaged pulp. But your body still needs time to heal. Pain can occur for these reasons:​

Inflammation: Tissue around the tooth can swell as your body heals. Even without the tooth’s main nerve, small nearby nerves can cause mild pain.​

Sore Jaw: Keeping your mouth open during the procedure can make your jaw sore. This usually goes away in a few days.​

Bite Issues: If the filling or temporary crown isn’t right, it can put extra pressure on the tooth, causing discomfort.​

Healing: Even after the infection is gone, your body is still fixing the area around the tooth, which may cause tenderness.​

What’s Normal After a Root Canal?​

Mild Discomfort: Feeling a bit of pain for a few days, especially when chewing, is normal. Over - the - counter painkillers like ibuprofen or acetaminophen can help.​

Slight Swelling: A little swelling or tenderness around the tooth is common and should fade in a few days. Sometimes, dentists prescribe antibiotics.​

Tender Gums: Gums near the treated tooth might feel sore, but this will improve as they heal.​

Pressure Sensitivity: The tooth may feel sensitive when you bite down. This is because the surrounding tissue is still healing and usually stops soon.​

When to See a Dentist?​

Contact your dentist right away if you have:​

Severe Pain: If the pain is bad and doesn’t get better in a few days, the infection may not be cleared or there could be other problems like a cracked tooth.​

Swelling that Stays: Mild swelling is normal, but if it doesn’t go away or gets worse, it could mean an infection.​

Constant Temperature Sensitivity: If the tooth is still sensitive to hot or cold after treatment, there may be an issue with another tooth.​

How to Manage Post - Root Canal Pain​

Take Painkillers: Over - the - counter meds can ease discomfort. Just follow the package instructions or your dentist’s advice.​

Eat Soft Foods: For a few days, avoid chewing on the treated tooth. Choose soft foods like yogurt or mashed potatoes.​

Brush and Floss Gently: Keep your teeth clean, but be careful around the treated tooth to avoid irritation.​

Don’t Miss Appointments: Go to your follow - up appointments. Your dentist will check healing and decide if you need a permanent crown.​

How Long Does the Pain Last?​

Most people feel mild discomfort for a few days. The pain should improve a lot within a week. If it doesn’t or gets worse, call your dentist.​

Some pain after a root canal is normal, but it should get better soon. Take care of your teeth and follow your dentist’s advice. With good aftercare, you’ll be back to normal quickly!
