Let’s face it—no one wants to hear the words “you need a root canal.” While the root canal procedure is a fantastic way to save an infected tooth, wouldn’t it be even better to avoid needing one in the first place?

Good news: in many cases, root canals can be prevented with the right habits and care. At Eastern Idaho Endodontics, we love helping patients protect their natural teeth for life. So let’s talk about what causes root canals—and more importantly, how you can lower your chances of needing one.

First, Why Do People Need Root Canals?

A root canal procedure becomes necessary when the pulp—the soft inner tissue of your tooth—gets infected or inflamed. This can happen for a few common reasons:

  • Deep decay (a cavity that reaches the nerve)

  • A cracked or chipped tooth

  • Repeated dental procedures on the same tooth

  • Trauma to the tooth—even if there’s no visible damage

Once the pulp becomes infected, it can’t heal on its own. That’s when a root canal is the best way to clean out the infection and save the tooth.

5 Ways to Help Prevent a Root Canal

1. Brush and Floss Daily

It sounds basic, but brushing twice a day and flossing once a day is your first line of defense against decay. Removing plaque and bacteria helps prevent cavities from getting deep enough to require a root canal.

2. Don’t Skip Dental Checkups

Even if your teeth feel fine, regular cleanings and exams help catch issues early—long before they turn into infections. Your dentist can also apply sealants or fluoride treatments to give your teeth extra protection.

3. Wear a Mouthguard (If Needed)

Do you grind your teeth at night or play contact sports? A custom mouthguard can protect your teeth from cracks and wear, both of which can expose the pulp to infection.

4. Treat Cavities Early

A small cavity is no big deal when caught early. But if it’s left untreated, it can grow deeper and reach the nerve—leading straight to a root canal procedure. That’s why we always say: don’t wait until it hurts.

5. Watch What You Eat

Sugary and acidic foods can wear down your enamel, making your teeth more vulnerable to decay. We’re not saying you can’t have a treat—just be mindful, rinse with water afterward, and brush regularly.

What If You Still End Up Needing One?

Even with the best care, some root canals are simply unavoidable—especially if trauma or genetics are involved. The good news is that today’s root canal procedures are nothing like they used to be. They’re fast, comfortable, and incredibly effective at saving your tooth.
