55 (25/30) total units on both sides. 5-6 injections on both sides of jawlines to slim face. After 2 wks of injections, there was no saliva from the sides and the bottom of my mouth. My mouth is really dry. Is it possible that Botox was injected into the parotid and submandibular glands by accident to cause saliva suppression? Is it possible the glands are damaged permanently by botox? How long does it take to wear off if Botox is injected into salivary glands?
