Botox is a trade name for botulinum toxin, which comes in the form of a purified protein. Botox can be used to decrease the unsightly frown lines between the eyes and to smooth facial wrinkles. Botox has useful clinical uses as an adjunct in TMJ and bruxism cases, even more so for patients with moderate chronic temporomandibular joint and facial pain. It is also often used in conjunction with dermal filler therapy as a non-surgical alternative to high lip lines.
