Leeray, definitely agree with Naomi...that is exactly the one I use...I had ultra sensitive teeth and although I was a Colgate girl all my life, it took me a few days to get used to Sensodyne but i wouldn't be without it now. I can even have ice cream now!
I agree with all the above. Arm and Hammer also have a good one that is also supposed to repair tooth enamel. That is the most succesful one that I have used yet. Persevere with it, it may take time, but eventually you will notice a difference.
Like oldmegan I use the Arm & Hammer Enamel care and, just as importantly leeray, find a good toothbrush. I've found the Sensodyne one is by the far the best I've ever used. The dentist has asked me to have a clean and polish every 3 months - little & often is less painful!
