Chiropractic adjustments make a popping or cracking noise because small air bubbles that build up from pressure in between the joints are released. The noise isn't the bones touching, or cracking. The noise isn't dangerous, and it doesn't cause damage. Some patients love to hear the popping noise, and some would rather us use different chiropractic techniques that don't require the popping or cracking noise to fix the spine. We are trained in traditional and gentle techniques so the patient is comfortable.
