I had 11 dents on the roof of my other car near the passenger doors, some of them deeper and bigger than yours. They pulled them out and it's like new again.
They told me that this method was safe as long as there were no prior repair or bondo where they apply the glue. There was also a risk that the glue would not be strong enough, but in my case it worked perfectly. It didn't leave any marks on the paint either.
