Review title is very abrasive - made for a person with a mouth of steel [SEP] I wanted an inexpensive sonicare but the brushing is so extreme that it pushed back my lower gum.  It went back but this is the most abrasive tooth brush I've encountered.  I do not think I have sensitive teeth or gums, but my teeth felt like I was wearing down my gums after a few weeks.  I don't recommend this to anyone.
