Jaw Tension & Bruxism

Jaw Tension & Slimming

Relax · Relieve · Refine

Defined by Paris — Refined by Seoul — Excellence on Harley Street

22 Harley Street· CQC Regulated· Prescription-Only Medicine

Clenching or grinding your teeth at night — often without realising it — can leave the jaw muscles overworked, leading to tension, headaches, and a wider, squarer jawline over time. A single, simple treatment can relieve the discomfort and soften the jawline together.

Bruxism — the involuntary grinding or clenching of teeth, often during sleep — causes the masseter muscles at the back of the jaw to become overworked, much like any muscle that's exercised every day. Over time, this can lead to the muscle bulking up, widening the lower face, as well as causing jaw pain, tension headaches, and wear on the teeth.

Treatment involves precise injections of botulinum toxin into the masseter muscles. This relaxes the muscle, relieving tension and pain, while gradually reducing muscle bulk — softening and narrowing the jawline for a more refined lower face.

What This Treatment Addresses

✓

Jaw Tension & Pain

By relaxing the overworked masseter muscle, treatment can ease jaw tension, tightness, and discomfort — including pain on waking.

🥺

Headaches

Tension headaches associated with clenching and grinding often improve as the muscle relaxes.

✨

Jawline Slimming

As the masseter muscle gradually reduces in size, the lower face appears softer and narrower — a more refined, V-shaped contour.

“This is one of those treatments that addresses two things at once — patients come to us for jaw pain and leave noticing their whole face shape has softened.” PHP Aesthetic-Wellness, 22 Harley Street

What to expect: relief from jaw tension is often noticeable within a couple of weeks, while jawline slimming develops more gradually over several weeks as the muscle reduces in size. Results typically last 3–4 months initially, with repeat treatments often required less frequently over time.

Bei Dr. Philippe habe ich mich von Anfang an in besten Händen gefühlt: professionell, einfühlsam und präzise, mit einem Ergebnis, das natürlich und mühelos schön wirkt.
Von Herzen vielen Dank an ihn und PHP Aesthetic!
