This Review Title is They Just Don't Work and the content is: I've used DenTrust &#34;surround&#34; toothbrushes along with Collis Curve toothbrushes for years and years, and my teeth stay squeaky clean.  In a rush (my own fault) I bought Surround Toothbrushes by mistake.  They just do not work.  I (carefully) ordered DenTrust brushes again, and now feel clean.  I honestly don't understand all the great reviews for these toothbrushes.  I gave one of these to my husband and he hated it.  I gave two more away --to my daughter and her husband -- and they threw them out.  If you try these and try DenTrust, you'll feel the huge difference..There are other information for this review, one is This reviewer did purchase it and the other is 2 people think this review is helpful.
