Lip Incompetence and Mentalis Strain- Easiest Way to Fix? (photo)

It sounds and looks like you need to have a thorough assessment of what's happening with your bite and/or jaw with your dentist. Botox properly injected in the masseter muscles decrease them in size and strength and won't affect your mentalis. Treatment to your chin or mentalis muscle will do the opposite of what you need, by relaxing the muscle.

Hello,

Thank you for the question and photos.  You are correct, botox to prevent or minimize mentalis strain would diminsh your ability to bring your lower lip upwards to meet the upper lip.

All the best,

Dr Remus Repta
