Several states, including Iowa, Ohio and West Virginia, already allow dentists to give their patients Botox injections. While some patients may be enticed by the option to have their teeth whitened while simultaneously receiving anti-aging injections, medical experts warn that the practice may be dangerous, according to The Tennessean.

Dentists looking to manage their patients’ substantial pain from temporomandibular disorder, or TMJ, are using Botox in an off-label, non-FDA approved manner. The Tennessee Medical Association (TMA), argues that the use of Botox in dentists' offices could blur lines between pain management to cosmetic procedures.

The Physicians Coalition for Injectable Safety states that those who are considering undergoing a cosmetic Botox treatment should have the procedure performed by qualified injectors. The skill needed to inject Botox and treat for any complications requires training and experience that may otherwise be missing from non-core specific physicians.

The clinical effects of Botox treatments typically last three to four months, according to the American Society for Aesthetic Plastic Surgery.

Trends indicate that soft tissue fillers are growing in popularity to treat larger lines of facial aging, but consumers should only proceed with qualified injectors.
