Pain After Root Canal: What You Should Know

When your teen or older child needs a root canal, it’s completely natural to feel a little anxious—especially if they’re dealing with pain afterward. While root canals are designed to save teeth and relieve pain caused by infection or damage, some discomfort during recovery is totally normal. Knowing what to expect and when to take action can help you feel confident in caring for your child as they heal.

Is Pain After a Root Canal Normal?

Yes—some discomfort after a root canal is to be expected, even for older kids and teens. The procedure itself removes the infected or damaged tissue inside the tooth, but the surrounding area may still be tender for a few days while it heals.

Common symptoms include:

  • A dull ache or sensitivity near the treated tooth
  • Swelling or mild inflammation
  • Sensitivity to chewing or hot/cold foods

This discomfort usually improves within a few days and can often be managed with over-the-counter pain relievers recommended by your child’s dentist.

When Should You Call the Dentist?

Most post-root canal pain is mild and temporary, but there are some signs that may indicate something more serious. Reach out to your dental provider if your child experiences:

  • Severe or worsening pain after the first few days
  • Swelling that doesn’t go down or gets worse
  • A fever or chills (which could point to infection)

Trust your gut—if something doesn’t feel right, it’s always okay to check in with the dentist. Early treatment can prevent bigger problems and help your child heal faster.

Helping Your Teen Manage Pain at Home

You can support your child’s recovery by helping them stick to a few simple steps:

  • Give any prescribed or recommended pain relievers exactly as directed
  • Use a cold compress on the cheek to reduce swelling
  • Encourage soft, easy-to-eat foods like applesauce, smoothies, or mashed potatoes
  • Remind them to brush gently and avoid chewing on the treated side until it feels better

These small habits can make a big difference in helping your child feel more comfortable during recovery.

Keeping That Tooth Healthy for the Long Run

Once your teen’s root canal site is healed, long-term care is key. Here are a few things their dentist might recommend:

  • Wearing a night guard if they grind their teeth
  • Staying on top of regular checkups and cleanings
  • Using fluoride toothpaste to strengthen enamel
  • Brushing and flossing every day to keep teeth and gums healthy

A successful root canal can last a lifetime with good care—and you’ll play an important role in helping your teen stay on track.
