Hi! Most of my teeth have white fillings and I know that it will not last a lifetime. I had also replaced some of them because those have been in my mouth years years ago. I know it should be replaced in time, but I'm afraid that it will get deeper and deeper into the root. Is there a high possibility that I would wear dentures in the future or that it will all be crowned? If i maintain oral hygiene and regular dentist check-ups is there a possibility that I will still be able to save all of my teeth? Thank You.
