To morning I went to my semi annual dental check-up and cleaning. The dental tech asked me the usual questions about whether or not I hve an dental pain and such. I told her no, but I brush my teeth too aggressively at times and combine that with flossing, my gums get irritated.
She she worked on me for a bit and said. "You use Listerine don't you". I told her I did because it's supposed to contribute to good dental health. She said that Listerine is among the worst mouth washes or rinses out there. She said it is harmful to your dental healt and contributes to gum disease. She said it also causes dry mouth and that's really detrimental to good dental health.
When she was done, the dentist came in to look me over. I told him that her comments surprised me because I've always heard just the opposite. He said " oh yeah, that crap is horrible, don't use it any longer. That's why your gums are irritated". I said " I buy it in bulk at Costco". He said "pour it down the drain. It might help keep your drains clean".
