Definitely not "ultra soft"
I bought this to apply a product between my teeth.  My hope was to get into the interdental spaces without brushing it off of the front of my teeth.  The shape of the brush is great for that, but I expected it to be as soft as a post-operative brush or a nano-bristle brush because of the 'ultra soft' description.  The bristles bend less than a regular soft toothbrush, probably because they are more compact together and shorter.  I think it would do a good job cleaning around braces and implants.  However, if you have gum sensitivity and are looking for something soft, this isn't the right brush.
