What Happens if I Don’t Get a Root Canal?

When your dentist recommends a root canal, it’s usually not a suggestion—it’s a sign that your tooth is in serious trouble. Root canals are needed when the inner pulp of your tooth becomes infected or severely inflamed. Without treatment, that infection doesn’t simply go away. Ignoring it can lead to pain, deeper infection, and even tooth loss. Here’s what can happen if you don’t get a root canal when it’s needed.

The Pain Will Likely Get Worse

A tooth that needs a root canal often starts with sensitivity, aches, or sharper pain. Without treatment, the infection inside the tooth grows. Pressure builds, nerves become more inflamed, and the pain usually becomes more intense and frequent. Some patients experience throbbing, swelling, or a constant dull ache that affects their sleep and daily life.

Occasionally, the pain may temporarily subside. While this may feel like a relief, it’s actually a red flag. It often means the nerve inside the tooth has died—but the infection is still there and can spread.

The Infection Can Spread

An untreated tooth infection doesn’t stay contained. It can spread to the surrounding bone, gums, and even your face or jaw. This can lead to:

  • Abscesses, which are pockets of pus that cause swelling and severe pain.
  • Bone loss around the tooth.
  • Facial swelling or difficulty opening your mouth.
  • Fever and general illness.

In more serious cases, the infection can spread to other parts of the body, which can become a medical emergency.

You Could Lose the Tooth

When infection damages the inner structure and root of a tooth, it becomes weaker and more unstable. Eventually, it may crack, break, or become too compromised to save. At that point, the only option is extraction.

While tooth removal may seem like a simpler solution, replacing a missing tooth can be costly and time-consuming. Implants, bridges, or dentures may be needed to restore function and prevent shifting of nearby teeth.

Long-Term Oral Health Issues

A missing or infected tooth can create a domino effect. Shifting teeth can affect your bite and make chewing difficult. Nearby teeth may also become more vulnerable to damage. Inflamed or infected tissue in the mouth can even impact your overall health, increasing inflammation throughout the body.

Delaying a root canal rarely improves the situation—in fact, it almost always makes it worse. Early treatment can relieve pain, stop infection, and preserve your natural tooth. If you suspect you need a root canal, don’t wait. Your dentist can help you protect your smile and restore your comfort before the problem becomes more serious.
