Dentists that actually care in MTL (recommendations)

I would like to see a dentist that actually cares about my dental health and is good at their job. and the fact that i don't want to plug every cavity I have. I don't have good dental genes so I end up with tons of little cavities, I don't have the money to cover up all the holes as they want to. I wish they could just focus on the ones that are actually sensitive (atm, only barely 2 for instance) and leave the rest. My last dentists would also flame me for not being a big girl and taking care of my teeth properly (their techniciens tried showing me the proper way of flossing my teeth at least 5 times and their string breaks everytime. They blame the string type yet i have no problem flossing my teeth with any type of string.) I guess its my fault for going to cheaper clinics due to the fact that I take the appointment with my parents so we can all do it in one go and I get a free ride.
I live in the st-leonard area, but I'm honestly so open to suggestions. I also work in the old port, so it's not like I can't be elsewhere, just not in the west. I'll see if they cover my uni insurance! Im fluent in both english and french, i do prefer english a smidge bit but will take a good french dentist anyday (that doesn't make unnecessary fixes to cavities (sorry for my ignorance) for money).

EDIT: did not expect to have so many responses to this! Thank you so much, i appreciate this so much :) its been so long since i’ve wished to get good recommendations. My experience with dentists have been so dreadful. Even with high tolerance for pain, just attitude/value wise. Thank you again!!! I love this community :)
