Jaw slimming
Square or wide jaw
A wide jaw from the masseter muscle is the usual reason to look at jaw Botox. It is botulinum toxin, like the wrinkle treatment, with a higher unit count and a different price. The slimming shows up over weeks, not hours, and it wears off.
Teeth grinding is a separate reason some people are offered the same injection. A cosmetic directory is not a dental or medical assessment. Use the Jaw Botox page to see how clinics separate it from a standard per-area Botox price.
This is general information, not a medical recommendation. A registered doctor should decide whether a treatment is suitable for you.
