I am 30, I have 2 cavities, I just went in for a cleaning and have a clean bill of health. My teeth have always been sensitive to gummy type snacks, so I just don't eat them. Increasingly so, my teeth are more sensitive after this last pregnancy. In so much that a JP gummy will drop me on the floor in pain. Dentist's verdict is "some people just have sensitive teeth". Well, being the whole-body person, that's crap. So what is it? I have ALWAYS used glyserin toothpaste, Toms of Maine, but went on regular Crest Sensitive with Flouride for 1 month, and noticed no difference. We drink flouride free water, for the past 2 + years. Again, I have virtually no cavities, no concerns about enamal.
I am nursing still, just morning and night, an 11 mo. old. Perhaps my calcium instake is a little low and I probably could drink more water, better hydration. I had thrush last month and was on a virtually sugar free diet, and as little carbs as I could tolerate...that made no difference.
I'm to the point where I think I just need to try some sensodyne and forget it, but if I could find the cause (if there is something beyond "some people are just..." I would be a much happier camper. 30 is too young to have tooth sensitivity like this "forever".
My sensitive teeth get better when I do one or several of the following: mineral supp (about equal amounts of cal and mag, plus other minerals, though I think those are the most important for this), improve my vitD status, supplement K2 (most people wouldn't notice this last one as much, my family seems to have an odd quirk).
Sensitive teeth get worse when I: consume too much sugar, supplement vitA w/o being really diligent about the D and K2, eat chewy sweet things.
Cell salts are helping me need less of my mineral supp, so far just bioplasma, haven't tried the ones that are specific for dental issues.
Each of those has been more or less important at different times, so play around with it. If you haven't already read the cell salts thread in H&H, do that. These are the coolest supp I've come across in the past year.
Another thing is if your teeth are sensitive it could be from the roots, perhaps a little swelling. Nothing to be worries about and I am not saying this is it, but just some thoughts. As for root swelling, working on the liver will help with that.

I had terrible sensitive teeth after pregnancy. One of the things that helped me was to use a gentler toothbrush. I found that I had been brushing so hard and often I was wearing down the enamel. I tried some supplements without much improvement.
