The bristles of the brush are very smooth and do not hurt the gums when brushing. Fits very well on my toothbrush head. Includes 10 interchangeable heads. I just received them so not sure how long they can last but they seem to be great quality. The lifespan also depends on how often you prefer to brush your teeth. I prefer twice a day and I think a full box can last about a year. Worth the price and overall I'm happy with the quality and they aren't too hard on my teeth.
