Shoppers have left rave reviews after putting a dental water flosser to the test. Unlike the regular method of flossing, a water flosser can be great for hard-to-reach areas or for those who have sensitive teeth and gums. 

COSLUS makes several different types of water flosser which can be purchased on Amazon. Currently, the COSLUS 300ml water flosser is reduced to less than £20 as part of Amazon’s Black Friday deals. 

The flosser comes in a range of colours, with the black currently discounted to £18.99 and the mint green to £17.99.

Equipped with 4 cleaning modes—Normal, Soft, Pulse, and DIY—it offers a customizable experience, making it suitable for all ages and oral care needs.

The flosser’s ergonomic, cordless design and long-lasting rechargeable battery – up to 30 days per charge – make it a practical choice for both home and travel use.

Particularly popular on Amazon, reviewers find it “gently cleans the mouth and leaves their teeth feeling clean”, adding that “it’s a good water flosser and much better than flossing the old way.

One buyer said: “I bought the COSLUS Water Teeth Flosser a few months ago, and it’s completely changed my daily dental routine. For anyone who finds traditional flossing a hassle or wants a more thorough clean, this flosser is a must-have.”

Another added: “My dentist told me that my gums were in a very bad way. I did a lot of research on this product and it has been amazing!! You need to start on a low mode and then get used to it first. Five stars all the way.”

However, a separate shopper noted: “Very hard to see the modes and other markings (open/closed next to the charging port).”
