For a joint that's unstable or prone to dislocating rather than simply tense, prolotherapy targets the ligaments directly — and the evidence behind it is more solid than you might expect.
What it's actually for
Prolotherapy is aimed at a specific kind of problem: a joint that's unstable, prone to dislocating, or has weakened supporting ligaments — rather than pain that's primarily coming from overworked muscles. It's a particularly relevant option for people with jaw hypermobility, including those with EDS or hypermobility spectrum disorders, where the ligaments themselves are the underlying weak point.
How it works
A dextrose (sugar water) solution is injected into the ligaments and tissue around the joint. This creates a controlled, mild inflammatory response, which triggers the body's natural healing process — over a series of sessions, this is intended to build stronger, more stable connective tissue around the joint.
What the research actually shows
Prolotherapy for TMJ isn't a new or fringe idea — it was first described in the scientific literature for TMJ treatment back in 1937. More recent research has been genuinely encouraging: one study found average pain scores falling from 4.3 to 1.0 on a 10-point scale, with maximum mouth opening improving substantially, and reported success rates above 90% at long-term follow-up in some studies.
Where it fits
This is a non-surgical option generally considered for jaw instability, recurrent dislocation, or chronic pain that hasn't responded well to more conservative measures — a middle ground between things like splints or trigger point injections and more invasive surgical options. It's performed by a trained provider, not something to pursue outside a clinical setting.
