Title: Pricey but worth it!
Review: The extra soft is much more gentle than the standard soft. Noticeable difference, particularly if you have sensitive teethThey wear fairly well though not quite as long as the regular soft brushes. This is probably because with electric toothbrushes you don't use as much pressure on your teeth.Another option to get them inexpensively is to use a 20% off coupons at Bed Bath and Beyond which carries all the Oral B heads
