Botox Units Needed to Correct Gummy Smile?

A typical Botox dose to address a gummy smile is anywhere between 4-6 units to the upper lip, and if needed, 4 units right under the nose area.

 Good Day Oz Girl,
It takes about 5-6 units of Botox to treat the gummy smile, even in Aussies.  Make sure that you choose a physician who is experienced in this area of injections.  
Good luck and be well.
