Anti-clenching treatment involves using neurotoxin to relax the overactive jaw muscle “masseter”muscle. This over activity due to clenching or teeth grinding can cause the masseters to increase in size and as a result can give a square like jawline and a masculine appearance. Anti-wrinkle injection selectively weakens this muscle over time leading to an overall reduction in the size of this muscle resulting in reduced pain and a slimmer jaw giving a more feminine appearance.
