I am fairly new to toothpasting but have tried a few times now and absolutely love it. I have mainly been using sensodyn because that's what my mum buys and to be honest I have sensative nipples and it has taken me a while to get used to it and build up a tolerance. I am now wanting to move on to something a little stronger so really want to know what the strongest toothpastes are for toothpasting? I love the high that I get but I would like it to be more intense and longer lasting if possible, but still leaving me a crispy mint chap.
