If you’ve ever had a chiropractic adjustment, you’ve probably heard that satisfying “pop” or “crack” and instantly felt some relief. But what exactly is that sound? Is it your bones cracking, something being put back in place, or something else entirely?
As your trusted chiropractor in Toronto, Dr. Matthew Hannikainen at The Well Adjusted Chiropractic Centre is here to break it down and help you understand the true science behind the sound—and the healing power of chiropractic care.
Let’s demystify the “crack” and explain what’s actually going on when you receive a chiropractic adjustment from our Toronto chiropractor.
What Causes the Cracking Sound During a Chiropractic Adjustment?
The popping or cracking sound that sometimes occurs during a chiropractic adjustment is known as cavitation. Cavitation happens when gas bubbles within the synovial fluid of a joint rapidly collapse or are released due to changes in joint pressure.
Here’s what that means in plain language:
Your joints are surrounded by a capsule filled with synovial fluid, which lubricates and nourishes the joint.
Over time, gases like nitrogen and carbon dioxide dissolve in this fluid.
When a chiropractor gently adjusts or stretches the joint during an adjustment, the pressure inside the joint changes.
This pressure change causes the gas bubbles to quickly release—creating that characteristic “pop.”
Important Note:
This sound is not your bones cracking, nor is it what “fixes” the problem. It’s simply a side effect of a rapid pressure change within the joint. Whether or not you hear a pop, the adjustment can still be effective.
Does the Crack Mean the Adjustment Worked?
While the sound is common, it’s not an indicator of success. A great chiropractic adjustment restores mobility, improves alignment, and reduces pressure on your nerves, whether or not you hear a pop.
Some adjustments might not create any sound at all, yet still deliver measurable results.
As our best chiropractor in Toronto, Dr. Matthew Hannikainen explains to patients that it’s the movement and positioning of the vertebrae, not the sound, that creates the therapeutic effect.
What Are the Benefits of Chiropractic Adjustments?
Even without the pop, adjustments help:
Restore proper joint movement
Reduce muscle tension and spasms
Improve nervous system function
Decrease pain and inflammation
Promote better posture and mobility
If you’ve ever looked up a chiropractor near me and wondered whether the cracking sound means you’re being “put back into place,” the answer is a bit more complicated.
Is Cavitation Safe?
Yes—when performed by a licensed and experienced Toronto chiropractor, cavitation during adjustments is completely safe. At The Well Adjusted Chiropractic Centre, every patient undergoes a full assessment to ensure that chiropractic care is appropriate for them.
Dr. Hannikainen customizes each adjustment technique based on your needs, preferences, and spinal health. Whether you’re new to chiropractic or a regular visitor, your safety and comfort come first.
Why You Shouldn’t Try to "Crack Your Own Back"
Many people feel tempted to twist or stretch their back or neck to achieve that same popping sound. However, this can be ineffective or even harmful.
Why it’s risky:
You may overstretch already mobile joints while missing the restricted ones.
Repetitive self-cracking can lead to instability or worsen misalignments.
You lack the precision, training, and diagnostic skills of a licensed chiropractor in Toronto.
Instead of risking injury, visit our chiropractor who understands the mechanics of each vertebral segment and can safely deliver targeted chiropractic care.
What If You Don’t Hear a Pop?
Again, not every adjustment will produce cavitation. That’s okay. Some gentle chiropractic techniques are still highly effective despite their being no sound!
Examples include:
Activator method: Uses a small handheld instrument for low-force adjustments.
Drop table techniques: Relies on gravity and a special table for precise spinal corrections.
Mirror Image Adjusting: Focuses on correcting your posture to help achieve spinal correction.
At The Well Adjusted Chiropractic Centre, we offer a variety of methods to meet your comfort level and goals. We focus on results—not noise.
