Wrinkle Relaxers for Teeth Grinding/Masseter relaxation

Comfort and contour in one treatment

Jaw clenching, teeth grinding and tight masseter muscles can cause daily discomfort — from tension headaches to jaw pain and tooth wear. Wrinkle relaxers placed in the masseter muscles help reduce this tension, providing relief while also slimming the lower face for some patients.

Ease jaw tension, protect your teeth, and relax your facial muscles.

  • Relieves clenching and grinding.
  • Helps reduce jaw pain and headaches.
  • Softens a square or bulky jaw.
  • Noticeable comfort within weeks.

Masseter wrinkle relaxers work by softening the overactive jaw muscles responsible for clenching and grinding. As these muscles relax, pressure on the jaw joint decreases, helping reduce headaches, tension, facial discomfort and nighttime grinding. Many patients also notice a slimmer, more tapered jawline as the masseters gradually reduce in size. Each treatment at Sisu Clinic is delivered by our medical team, ensuring the correct dose for both relief and natural facial movement.

This treatment works by interrupting the nerve signals that cause unconscious clenching. By reducing the strength of the masseter muscle, studies show a decrease in tooth grinding, facial tension, and stress-related jaw pain — all while keeping natural chewing function completely intact.

What to Expect During Your
Teeth Grinding Treatment

<strong>Consultation & Assessment</strong>
Consultation & Assessment
Your Sisu Clinic provider will assess your jaw movement, clenching strength, and any related symptoms such as headaches or tension. Together you decide the ideal amount of product for comfort and facial shape.
<strong> Precise Injections</strong>
Precise Injections
Small, quick injections are placed directly into the masseter muscle. The treatment takes around 5–10 minutes and feels like tiny pinches — no downtime required.
<strong> Gradual Relief & Improvement</strong>
Gradual Relief & Improvement
You’ll start feeling reduced tension within 7–10 days, with full results at 4 weeks. Over time, the muscle softens, easing grinding and subtly narrowing the lower face.
Ease Jaw Tension.

Ease Jaw Tension.

Women often carry jaw tension without realising it — especially during stressful periods or sleep. Masseter treatment helps soften clenching, protect the teeth, ease headaches, and gradually refine a strong jawline for a softer, more balanced facial shape.

Strong Jaw, Less Tension.

Strong Jaw, Less Tension.

Men tend to have stronger, more active masseter muscles, which makes clenching and grinding more intense. This treatment helps reduce pressure, ease tightness, and protect long-term dental health — all while keeping the jawline looking strong and natural.
