Review title is They Just Don't Work [SEP] 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.
