For Waltham I recommend Dr Damien Meola Smile and Skin Aesthetics. They did all my dental work past year and I am working with them and ortho to do Invisalign. I was pretty scared of dentist before them so they have been really great about dealing with my anxiety and also getting my thru a bunch of things to go thru to get to Invisalign. They bring in an ortho for that which most dentist don’t know better to do, which I also appreciate, anyway, other option in Waltham for you! Good luck!
