Drugs used for moderate sedation such as Lorazipan and Triazolam both have lactose which may be animal derived. As noted by others, anesthetics use eggs. I think it is great that you are looking into a Vegan option for your anesthetics. However, as the website below talks about, as a vegans try to avoid animal products "'as far as practical and possible.'" I think you can safely say that it is not practically possible to take care of you teeth and avoid any animal products.
