Is dental putty safe to use with veneers?

Hi, I am looking to have treatment on my teeth to straighten them. I have been advised to take impressions of my teeth prior to receiving orthodontic treatment (clear aligners), using an impressions kit containing dental putty. However, my two front top teeth are veneers. If I use the dental putty is it safe to use on my veneers? Or will it damage them, and could risk them falling out?
