Review title is Bristles frayed pretty quickly [SEP] I really wanted to love this product.  My child doesn't brush thoroughly, and I thought that anything that covered the entire surface area of the tooth would be much better than her regular toothbrush.  She liked it a lot, but I'm not sure that she was using it in a way that really covered all of her teeth.  After a short while, the bristles became frayed.  We reluctantly switched back to her old toothbrush.  I'm not sure if it was improving her brushing or not, and the price was much higher than the regular brush.
