Q. Dear Dr. Caplan, I am 34 years old and used to have fantastic teeth (needed my first ever filling when I was 18), but for some reason within the last 5 years my teeth have pretty much rottened/crumbled away. I’ve been told by a dentist that this is due to chewing a lot of sugary gum. I have continously been undergoing several treatments (6 extractions, root canal, crowns etc.) but it seems to have just worsened the situation. Whatever crowns get put on my teeth seem to come apart withing a couple of months damaging more of what little tooth is left. I am now at a point of considering having what is left extracted and wearing dentures. could you give me your opinion (pros/cons) on this as I am getting very conflicting advice. Also do you know how long I would have to be without any teeth until I can wear dentures? Many thanks
