NOT FIRM, VERY SMALL HEAD & END GETS MOLDY! [SEP] SHORT VERSION:<br />This is NOT FIRM or MEDIUM as advertised, it is softer than the soft toothbrush my dentist gave me and since most toothbrushes sit in a cup or a fancy decorative toothbrush thing, then end gets moldy.<br /><br />LONG VERSION:<br />I ordered this since they advertised that it was NOT a soft bristle, but firm/medium.  This toothbrush was made with unicorn hair.... super soft and just silly.  Years ago, once I started using firm toothbrushes (properly), I have only light plaque at each 6 months dental cleaning and have not had any cavities.<br /><br />When I received them, I noticed the head is NOT ADULT, I don't care WHAT these other reviewers say and they had to have been paid off because I have a small mouth and this size was just stupid.  I was willing to try it and as I used it, it was like the unicorn hair got softer and softer!  I compared it to my firm toothbrush it was replacing and I am sorry, no comparison.  I like CLEAN teeth which is obtained in a SHORT time with a firm brush.  If I wanted to spend 2 minutes brushing my teeth I would just use the toothbrush the dentist gave me!<br /><br />I was going to go to the .99 store and get more but I saw the BAMBOO handle and thought, wow that is earth friendly!  Well, mold is earthy too so if you still want these soft bristled brushes for infant's teeth, make sure you HANG them and do not set them in a cup where the mold will grow from the water that drips down.
