This should be chosen with care, because the brush is not the same brush. Most of all I formerly used the gentle polishing "ProBright" that I did for a while could not find in stores. Besides, I could not find that the teeth through the use of which are white, although will become so. A good clean feeling mediated the brush but in any case.
Then I came in a discount store in a value pack of "Precision Clean", which is but too rough for my taste. Perhaps the reason is that this has specialized in the interdental spaces.
Then I discovered here at Amazon, the "Sensitive Clean". This is significantly more pleasant and I agree with another reviewer that this brush seems to last longer than z. B. the "Precision Clean". Surely that depends in part on the individual brushing habits; but I also think that it is because the bristles of the "Sensitive Clean" press on less firm and are per se softer. This also corresponds to the current recommendation of dentists, not too tight to brush your teeth to conserve tooth enamel and gums. Since the cleaning performance is equally good, I feel much better off with the "Sensitive Clean". This is especially true if, like me, has sensitive tooth necks.
