How long does it remove stinky breath for, like all day long or for just like a couple hours? Also is removing bad breath its main purpose ?

I use it to combat bacteria which was causing inflamation of my gums which in turn caused bad breath. I no longer have bad breath....

Would like to add to the warm water in my water pic. Is this recommend & how much should I add?

The short answer is no because you need to use it full strength to achieve maximum effectiveness. Here's the routine my dentist has me using and it (in 4 days of use twice daily) took the pockets in my gums from 12's & 14's down to 7's. After brushing for 2 full minutes (30 seconds on each side of teeth), rinsing and then flossing/hydroflossing I use my water pic in the morning and dental floss at night -- your teeth need to be clean and all the stuff in your mouth rinsed out: (1) Closys - ½ oz or two full capfuls for and swish around in your mouth for 30 seconds. Then spit it out.; (2) Antiseptic mouthwash like Listerine (with alcohol in it) - use 2/3 oz or 4 tsp. - there's usually a marker point on the inside of the cap and swish around in your mouth for 30 seconds. Then spit it out; and, (3) Act fluoride rinse without alcohol - use 10 ml (there is usually a marker in the cap or use the squeeze and measure up to the line on the bottle with a pump). Swish around in your mouth for a full minute. Spit and then don't eat, drink or smoke anything for a full 30 minutes to ensure that the protective coat fully dries to protect your teeth.

Do you just add the little tube of flavoring to the whole bottle if you want it to be minty?

Well I've never added the mint flavoring in because mint flavoring burns my mouth. But personally, I would add a quarter of the little bottle at a time, and then taste to see what you think. Mint has always been used to mask or neutralize mouth odors, so the proof of this product is that it doesn't NEED the mint. Your breath will smell just fine without the mint, once you start to use Closys regularly. It's most critical to use it at night, right before bed, so your mouth is squeaky clean for all those hours when saliva production (and protection) is at its lowest point. It also helps if you scrape your tongue clean with a tongue scraper, right before using the closys.

Is this mouthwash antifubgal?

CloSYS is antifungal and antimicrobial. We have data (in our patents) that CloSYS kills and inhibits growth of Candida (fungi also considered as microbes). Therefore, our claim “antifungal” & "antimicrobial."

Very good morning and night mouthwash.. no colour.. no taste

Good mouthwash for anyone who takes mouth hygiene seriously. Thought expensive but it's a non coloured liquid and taste free liquid. Helps with sensitive teeth and cavity protection.

I feel it's helping my teeth prepare for brushing and also kills bacteria

Very nice product. Bacteria streptococcus hates oxigen so this thing pushes oxigen into the mouth, great!

The mint flavouring is Gone Poof! AND IT LEAKS! watch out

totally bummed that the mint flavoring capsule is gone, this really made a difference especially for family members that sometimes can't tell the difference between this and water, and at time end up swollowing it. Seriously what was that about, and why not make it clear on your page here! in other words: Totally NOT AWESOME Dude! ====== Update ====== I travelled with one of the bottles and the cap does not seal at all, I was surprised to see that the entire bottle had spilled all over my clothes in the bag, this makes me thing Closys has serious quality issues? what was wrong with the original cap, it was beautiful and functional and above all it sealed in the liquids, HONESTLY I don't know what to say except that's it, I am looking else where.,
