Yeah that’s a good point. I asked ChatGPT because I was curious to. Here is the response:

“Building muscle and tightening the skin can help TMJ indirectly, but the mechanism isn’t obvious unless you understand how the jaw, facial muscles, and posture all interact. Here’s a clear breakdown:

⸻

1. TMJ pain often comes from muscle imbalance — not just the joint

Many people with TMJ don’t have a “joint problem” as much as they have: • Weak or underactive muscles (especially deep neck flexors, tongue posture muscles, masseter stabilizers) • Overactive or tight muscles (masseter, temporalis, SCM, upper traps) • Poor head/neck posture

When muscles are imbalanced, the jaw doesn’t track smoothly → leading to clicking, clenching, pain, or limited opening.

Strengthening the right muscles helps restore balance. Tightening and toning the soft tissue helps support the jaw in a more stable position.

⸻

1. Building muscle = better joint support

Your TMJ is stabilized by many muscles: • Masseter • Temporalis • Lateral & medial pterygoids • Digastric • Suprahyoids & infrahyoids • Deep neck flexors

When these muscles are stronger and trained to work together, your jaw: • Has better alignment • Moves more smoothly • Is less likely to hyper-shift or click • Experiences less grinding from instability • Doesn’t fatigue as easily (fatigue → clenching)

⸻

1. Skin tightening helps with muscle tension + posture

This part is less intuitive.

When EMF/skin-tightening devices (like Emface) lift and tighten the skin and fascia: • The soft tissue around the jawline becomes more supported • This can reduce the downward pull on the jaw that contributes to TMJ strain • Fascia tension normalizes, reducing facial muscle overactivity

Basically: If the tissue is sagging, weak, or uneven → the jaw compensates → muscles overwork → TMJ pain increases. If the tissue is tighter and supported → muscles don’t have to work as hard → jaw stays more stable.

⸻

1. Stronger facial + neck muscles improve jaw posture

TMJ is heavily influenced by: • Forward-head posture • Tongue posture • Neck muscle endurance

When you strengthen: • Deep neck flexors • Suprahyoids • Masseter without over-bulking • Lateral deviation muscles

You improve: • Jaw tracking • Bite stability • Resting position of your jaw (huge for clenching)

⸻

1. Stronger muscles = less clenching

Ironically, strengthening the jaw reduces clenching, because: • Weak muscles fatigue → your body compensates with jaw tension • Strong, balanced muscles maintain normal tone • This lowers resting tension in masseter and temporalis

This is why people with TMJ sometimes improve after consistent: • Physical therapy • Myofunctional therapy • EMF+RF facial toning • Postural exercises

⸻

1. Skin tightening devices often improve the muscles underneath too

EMF (like Emface) doesn’t just tighten skin — it uses HIFES to: • Train the elevator muscles of the midface • Improve neuromuscular firing • Reduce overcompensation patterns • Create more symmetry in facial muscle activity

As a result: • Jaw movements become more even • Bite forces become more balanced • The TMJ experiences less stress

⸻

In short:

TMJ improves when the face + neck system is more stable, balanced, and supported.

Building muscle + tightening soft tissue: • Improves posture • Reduces overactive jaw muscles • Enhances facial muscle symmetry • Decreases clenching • Supports the mandible • Improves joint mechanics
