MarketplaceListerine SamplesPosted on March 23, 2010. The use of Listerine every day bad for your teeth? I just read something online that said it was, but my dental hygeinist cleaned my teeth the last time but told me to use it every night and even gave me a free sample ... then who is it good or bad!? and if it's bad, what should I use instead?! Listerine is not bad for teeth. It comes down to personal preference. Listerine is effective in killing germs associated with gum disease and may help people who have infections of the gums and tissues. Some people do not like the sensation of burning. For young children, the alcohol can be a problem. Peroxyl and Crest Pro Health Rinse are other options. This is the best thing you can use every day. Continue to use it. Most people are concerned about alcohol in the product, because that consume large quantities of alcohol is linked to oral cancer, but the OS Listerine acohol in medical quality, and poses little risk. Never swallow Listerine, because it's unhealthy. If you're still not comfortable using it twice a day, use it once a day or every two days. I use about three times a week. The aim is always to brush and floss, mouthwash, as the use does not do the trick. CommentsThere are no comments.Leave a Comment | Popular My Friends |
