Fresh breath
7 September 2019christinac

Colgate Plax is a mouthwash that tastes nice and removes any food pieces and gives long lasting fresh breath. Use the cup at the top of the bottle to pour the product into and then rinse. It comes in a good size bottle 500ml. It left my mouth feeling fresh and refreshed. It comes in peppermint and freshmint flavors.

Does the job, mouth feels fresh and flavour lasts for some time afterwards. I dislike some other mouthwashes for being too strong and leaving a strange after taste. Colgate mouthwash is great and far better value for money!

Has a good mouth feel to it

This mouthwash came to me in a dental kit I purchased at a popular pharmacy in the CBD. Needless to say the packaging is easy to grip, and feels comfortable in the hands with an upmarket design.This mouthwash does work, yet it's also re-assuring to report that this product does not have alcohol (the Colgate Plax in the kit anyway). On the other hand, I do prefer Listerine alcohol free mouthwashes as the taste and after feel is more powerful with more food stuffs being released between each tooth prior to brushing.I still like this mouthwash, yet is a little weaker than other mouthwashes used.

My consistent performer, I rinse before brushing!

What they claim:The mouthwash clinically proven to protect teeth and gums from plaque bacteria for up to 12 hours.Kills germs by up to 99.9%, helps to keep gums healthy, delivers noticeable fresh breath, clinically tested by dentists.My thoughts on viewing the product:This is a decent sized bottle, at 500ml. It is easy to identify on the shelf with its bright red Colgate stripe, the light blue bottle and the white cap. It’s a good brand (i.e. Colgate), so really you are getting reliability.My thoughts on application:Let me throw this in there as a bit of a disclaimer.

This product is a part of My Spring Clean Challenge 2015 (a collection of products I have collected that have been sitting around and not being used).So I buy mouthwash when it’s on special. I admit it. It’s not exactly the cheapest product out there on the market. However, I like my teeth and I want to keep them as they are for as long as I possibly can. Prevention is key, so flossing, brushing and swishing is a part of that process.This is one of my go-to mouthwashes I prefer to buy if it’s on special. It has a light minty scent that doesn’t blow my mind (or burn my nostril hairs). And it’s the one I really like to use prior to brushing.My hot tip with this particular mouthwash is, after flossing, rinse your mouth with this mouthwash. The instructions state use 20ml. I don’t measure. I swig. I hope a duck swig is the appropriate amount. I swish prior to brushing and there is no burning sensation, it gets out any extra loose bits of food that the floss has extracted but is still in my mouth, it helps with the breath (particularly important if you’ve eaten something odorous), and it helps with the generation of saliva. Why did I raise this one? Well. I had an excellent conversation with my dentist who said very clearly that getting the saliva going after eating (i.e. chewing gum) will reduce the acid levels in your mouth and help protect the enamel on your teeth. So, I don’t brush immediately after eating. I do floss. I definitely swish and enjoy the lovely mint flavour and tingle on my tongue derived from this product. By the way, it also lingers on your gums, particularly after flossing, and I don’t find it irritating nor suffer a burning sensation at all. And then it also adds to the efficacy of your brushing. I love it!This is a product I have bought many times. Not time after time, but when it’s on special, I will buy. This mouthwash is a consistently great performer, doesn’t overpromise and definitely delivers. I highly recommend.

No sting
19 December 2018

I have hated using mouthwashes my whole life due to the stinging and burning feeling in my mouth. However for the past year or two I’ve switched to Colgate plax mint after my husband did the shopping and purchased it one time.This is the best mouth wash ever!!! It has a great minty taste, but there is no awful stinging or burning. It’s way to use and works as it should.

Not powerful enough
9 November 2018

Nowadays I am not a regular mouthwash user. I used to use Listerine daily, which is my preferred brand, but I use it now only a few times a week if I feel I am in need of a freshen up. A bottle of Plax was in a sample kit given to me by my dentist.The taste is minty and slightly underwhelming. I enjoy the 'sting' of mouth washes, which this one does not have, so for me this one doesn't give me that clean feeling - though I think in terms of oral hygiene, being in pain from a mouthwash is not a sign it is working properly! I didn't feel as though my mouth was healthier than other brands after using this. I think it is a good choice in a pinch if there is nothing else, but I wouldnt buy this after trying the sample.

Pleasantly minty
8 November 2018

Colgate Plax is a great everyday mouthwash that is both mild and very effective. It is very mild, so it suitable for everyone. It is fresh and minty, and leaves a pleasant sensation in your mouth.Just a small amount is needed, and you can use it twice a day to day to keep your whole mouth and teeth healthy. It helps keeps your breathe fresh, reduces tartar and leaves your teeth feeling cleaner and fresher. A good value mouthwash which is often on special so it is great to pick some up and keep your breathe fresher for longer.

Prefer this over Listerine
4 May 2016

I use the mint flavour (green). I have been using Listerine for a very long time, and got a big sample of this from my dentist. When I used it for the first time, I hated it. It is not strong and tingling like listerine so I did not think that it cleansed properly. I did not feel like it worked and i was also not used to the taste. A week later when I finished the first bottle, I purchased another one because it was on sale and much cheaper than Listerine. I have been using Plax ever since, and now I can't go back Listerine because it is too strong and has too much alcohol in it. I like that Plax actually works in its own way and without alcohol. I have also discovered the Plax fesh tes which is my preferred flavour.

Taste is Strong, but Too Strong
16 February 2019

This mouthwash does a good job of killing bacteria and giving your mouth a fresh burst. With that being said, the taste is strong. Personally, I don't like peppermint that much, but this is too strong for me.If you like peppermint, go for it.

Yummo Spearmint Aftertaste!
31 August 2018

I have this in Freshmint which is the green coloured one. It is alcohol free and is gentle on my cheeks when I swish with it. It doesn't have that biting burning feeling that mouthwashes used to have. I like this one a lot and find it really gives me confidence with how fresh my breath is. After swishing with this for 30 seconds I find that my mouth has a delicious spearmint-like aftertaste to it. I love that! My favourite mint is spearmint!!
