The Truth About Cracking Sounds During an Adjustment

If you’ve ever had a chiropractic adjustment, you may have heard that familiar cracking or popping sound. For some, it’s satisfying. For others, it can be a little unsettling—especially if they’re new to chiropractic care. So, what exactly causes that sound? Is it your bones cracking? And does a good adjustment have to include a pop? Let’s break down the truth behind the noise.

1️⃣ What Causes the Popping Sound?

The popping or cracking sound you hear during a chiropractic adjustment is not your bones cracking—it’s called joint cavitation. This happens when gas bubbles inside the joint fluid are quickly released due to a change in pressure. The sound is similar to what happens when you “crack” your knuckles. It’s a natural and harmless part of the adjustment process.

2️⃣ Is the Sound Necessary for a Successful Adjustment?

Here’s the good news: an effective chiropractic adjustment doesn’t always make a sound. The goal of an adjustment is to restore proper movement and alignment to your joints—not to create a pop. In fact, some techniques, especially gentle or instrument-assisted ones, don’t produce any noise at all but are still highly effective.

3️⃣ Does the Pop Mean Something Was Fixed?

While a popping sound can indicate that pressure has been released from a joint, it doesn’t always mean a correction occurred—and no sound doesn’t mean it didn’t. Chiropractors rely on their hands, training, and assessment tools to determine if the adjustment was successful, not just on what they hear.

4️⃣ Is the Sound Dangerous?

The cavitation sound is not dangerous. It’s simply a release of built-up gases like nitrogen and carbon dioxide. The adjustment itself is a highly controlled and safe procedure. Chiropractors are trained to apply the right amount of force in the correct direction to move the joint without causing harm.

5️⃣ Why Do Some People Love the Sound?

For many patients, the popping sound is associated with relief. That’s because releasing pressure in a restricted joint can improve mobility and reduce discomfort right away. However, even when there’s no sound, patients often still feel better due to improved joint function and reduced nerve interference.

6️⃣ Techniques That Don’t Involve Cracking

If you’re someone who doesn’t like the idea of a “crack,” that’s okay! There are gentle chiropractic techniques available that involve no popping sounds at all, including:
🔹 Activator Method (uses a handheld instrument)
🔹 Drop Table Technique
🔹 Flexion-Distraction

These methods are ideal for patients who prefer low-force adjustments or have specific conditions that require a gentler approach.

7️⃣ Communication is Key

If you’re nervous about hearing a pop—or not hearing one—talk to your chiropractor. They’ll explain what to expect and can tailor your adjustment style to fit your comfort level. Chiropractic care should feel safe, supportive, and personalized to your needs.
