I found this amazing product after reading "Kiss Your Dentist Goodbye" by Ellie Phillips which basically tells you to (in this order which is important): 1) Use CloSYS for 30 seconds and do not rinse 2) Brush your teeth for 2 minutes (I floss first) 3) Use an anti-sceptic rinse like Listerine for 30 seconds 4) Either rinse with fluoride for 1 minute or (in the case you don't trust fluoride) use Xylitol as a rinse to counteract the alcohol in the anti-sceptic rinse I healed 3 serious cavities in about 2 months. The dentist couldn't believe it. I couldn't believe it. I have xrays. Blew the dentist away. Plus my teeth were whiter than they had ever been before. Get that book too, explains it all, shows the scientific research, talks about stuff like xylitol gum, and has a LOT more info. So, I looked up the chemicals to find out how this stuff works. Here's a list of the ingredients in order of their amounts: water, stabilized chlorine dioxide, trisodium phosphate, citric acid First, a small explanation on where cavities come from. The two types of bacteria most frequently associated with cavities and periodontal disease are anaerobic, which means they live where there is little oxygen. Oxygen in your saliva actually kills them but if you sleep with your mouth open or have dry mouth, you will have problems (and bad breath). Sugar is also a problem, but surprisingly not because of sugar. But that same bacteria eats the sugar and literally poops acid that wrecks your teeth. Yes, bacteria poop is the stuff that rots your teeth. Ask your dentist. So here's how CloSYS works: 1) Chlorine dioxide: attacks the volatile sulfur gases in your mouth, neutralizing them and the smell they produce. Also produces oxygen that kills the anaerobic bacteria in your mouth. 2) Trisodium phosphate: An alkaline solution used as a cleaning agent, food additive, stain remover, and degreaser. This safely cleans and bleaches your teeth. That's it. It works well and is worth the price tag. I give it 5 stars. And just in case, so that you know this is a real review, I have no association nor do I work with any company for this review including the book I mentioned. I'm just regular guy with other reviews on Amazon here. Just thought I'd help and spread the word. Read more

Absolutely changed my gum health. I have seen a dramatic improvement in the last 3 moths. I use 2 x DAY, and even use in my water pic . Gums were red and irritated, so sensitive. 100% improvement. Not red or irritated at all. Highly reccommend! Will not burn mouth, no taste at all. It taste like water IMHO. Side note: I usually get a bad cold in the fall/ winter, not this year. Could be a coincidence, but perhaps it has improved my over all immunity. Read more

I ordered this product along with a CD on June 11 and about a week later Amazon informed me that it was "Undeliverable." I suspect the bottle became damaged and leaked. Amazon gave me a refund and I reordered the same two items on June 16. This time I received the two items, but one of the Closys bottles had a dent in one of its vulnerable bottom corners, as others have shown in these reviews. Fortunately, it did not leak. This mouthwash is excellent in keeping my mouth healthy, but the company should redesign and strengthen the bottles and Amazon should wrap the product with Bubble Wrap or other cushioning material besides just a strip of brown paper.

I'm so glad I found CloSYS Ultra Sensitive Unflavored Mouth Rinse, especially since I've been focusing on improving my gum health. This rinse has become a staple in my routine. The fact that it's truly flavorless is a huge selling point—it doesn't taste like anything, and it also doesn't leave a bad aftertaste. I use it both before and after brushing my teeth and using my water flosser, which leaves my mouth feeling incredibly clean. I love that it balances pH levels in the mouth and is made with clean ingredients: it's alcohol-free, sulfate-free, and triclosan-free. This makes it gentle yet effective. It's also an affordable option for daily use. If you're looking for a simple, effective, and gentle mouth rinse to support your gum health, this is it! Read more

This mouthwash has not taste, which is a plus because it does not burn or taste nasty. However, it does change the way water tasted at first (did not like at all) as well as foods tasting differently. I researched and read to use less product to help with the strange taste and that it will lessen as the mouth becomes a better ph. I have found that water tastes normal again, so it took me about 3 days to adjust. So far so good. I will update this review in time to share the longer-term effects. The packaging was well-done, and the item arrived in perfect condition. I highly recommend this mouthwash, especially for those who are experience early dental issues. Read more

I bought this as part of Dr Ellie Phillips' oral care system in which it is step 1. It doesn't irritate my gums and it's definitely killing bacteria but for the good results I guess it's the merrit of the entire system not just this one. My only bother is that this product came cracked even though the bottles are very sturdy and the product wasn't fully wasted. It was an international shipment and the product was labeled "heavy" but not "fragile" so I guess it was tossed around carelessly because nobody knew it was frail. The package contained no bubble wrap or anything that might absorb the shock as packages should especially for an international shipping. Read more
