I am in favor of allowing trained dentists to administer Botox and fillers. I have done botox for patients to help alleviate the pain of bruxism with great success. Allowing dentists to help patients with their overall esthetic is beneficial to patients and providers. Properly placed botox can help with overly gummy smiles, asymetrical smiles, etc. Dentists are trained in all the facial nerves and muscles...who better to administer botox! As far as filler, full lips can help create a gorgeous smile from a plain one.
