Botulinum Toxin in Dentistry

Abstract

Botulinum toxin (BT) is an injectable intermuscular medication that is used as a muscle relaxant. In this chapter, we explore the applications of botulinum toxin in dentistry for either cosmetic or therapeutic purpose, such as gummy smile (high lip line), parafunctional habits, temporomandibular disorders and facial pain. It is considered as a non-invasive, conservative and affordable alternative treatment in comparison to surgical procedures. Although, the effect of BT is temporary that lasts for 4–6 months, it is preferred by most of the patients as it gives positive significant results that meet their desires with minimal side effects.
