Botox and Fillers in Dentistry

Hey guys, Currently in my dental ethics course we are having a debate on the use of Botox and Fillers in Dentistry. I was placed on the side that is opposed to these techniques, but I am having a difficulty finding academic articles that also oppose the idea. If any one has any other information or even links to articles helping me out, please let me know.
