Bruxism — involuntary teeth grinding during sleep — is far more damaging than most people realize. Beyond wearing down enamel, chronic jaw clenching causes morning jaw soreness, temporal headaches, TMJ strain, and progressive masseter muscle hypertrophy that visibly widens the lower face. Coretox botulinum toxin injection is one of the most effective non-surgical treatments available, directly relaxing the overactive masseter without interfering with normal chewing.
How Bruxism Affects Your Health and Facial Structure
- Habitual clenching → masseter hypertrophy → wider jawline, square face appearance
- Chronic TMJ pressure → joint clicking, limited jaw opening range
- Repeated grinding → enamel erosion → tooth sensitivity
- Masseter-origin tension headaches centered at the temples and back of the neck
How Coretox Treats Bruxism
Coretox, developed by Korean biopharmaceutical company Medytox, temporarily inhibits neuromuscular signals in the masseter. The muscle relaxes, biting force decreases, and the grinding habit naturally diminishes — the same mechanism as jaw-slimming injections, but with dosage and placement optimized for bruxism management.
Key Treatment Parameters
- 20–30 units per side injected at the thickest point of the masseter
- Effects last approximately 4–6 months; grinding frequency significantly reduced
- After 2–3 treatment cycles, some patients experience long-term reduction in bruxism behavior
- Normal chewing and speech remain unaffected
Treatment Process
- Consultation: Doctor assesses masseter thickness, grinding severity, and TMJ status
- Injection: 2–3 injection points per side, completed in 10–15 minutes
- Onset: Masseter relaxation begins 1–2 weeks post-injection; morning jaw pain improves
Frequently Asked Questions
- Q1: How quickly does Coretox work for teeth grinding?
- Masseter relaxation typically begins 1–2 weeks after injection, with full effect at 3–4 weeks. Morning jaw soreness is usually the first symptom to improve.
- Q2: Is Coretox better than regular botulinum toxin for bruxism?
- Coretox has low diffusion properties, meaning it stays precisely where injected — important for a large muscle like the masseter where precision determines both therapeutic effect and aesthetic outcome.
- Q3: Can I eat normally after the injection?
- Yes. Biting force will be mildly reduced but daily eating is unaffected. Avoid extremely hard foods for the first 2 weeks.
- Q4: Does Coretox permanently cure bruxism?
- Botulinum toxin manages rather than cures bruxism. Maintenance injections every 4–6 months, combined with a nightguard if recommended by your dentist, provide effective long-term symptom control.
- Q5: Who is a good candidate for this treatment?
- Ideal candidates include those with audible nighttime grinding, morning jaw pain, temporal headaches, TMJ discomfort, or visible masseter enlargement contributing to a square-faced appearance.
- Q6: How do I book a bruxism consultation at Rappoel?
- The clinic is a 3-minute walk from Gangnam Station Exit 10. Book via WeChat (rappoelkr) or Line (rappoelkr) — Mandarin-speaking consultation available on request.
