I just found out I have sensitive teeth. I need a good tasting tooth paste for them.
My husband prefers Pronamel Sensodyne but I switched to organic brands such as Toms of Maine.
I agree with @prettygeek - I use Tom's of Maine.
I have to go with @prettygeek husbands choice, Pronamel Sensodyne, the wife and I have been using it for years and it works great for sensitive teeth.
Sendsodyne is most popular and everyone knows it but you should try something that helped me a lot when I had your kind of problem. It was propolis tooth paste . For some reason propolis from honey does wonders for your teeth.
You can actually buy propolis itself but it's easier to just use the toothpaste. Try few brand and see which one suits you the most and I promise you it will help you with sensitivity.
I think sensodyne works well but lately I have been using Colgate for teeth sensitivity and I have been very pleased with it.
