Filler and Veneers same day?

Hi doctors, I had cheek fillers done 3 weeks ago. Now I have peanut head and more pronounced tear troughs. I am scheduled to see a new injector but she can only get me in the same day I am having dental work done (removal of porcelain veneers, cleaning and temporaries applied). She wants to do temple, chin and tear trough filler on me but some places say you shouldn’t do these around the same time due to something called biofilm and increased risk for infection. Can I get both done same day?
