Bleurgh!
I'm currently using the ice flavour of this and having serious buyers remorse and it's severely testing my project pan. I was using a different brand and loved it but was short on money at the supermarket so went for this at half the price thinking how different can it be? Very different apparently.
My main gripe is the awful taste. It's not too atrocious at first but the lingering aftertaste is truly revolting. It's so bad that the man of the house refuses to use it and I'm left to gag my way through the entire bottle before I can buy my nice brand. I can kind of get through it by rinsing with water after but that kind of defeats the purpose.
The results don't stack up to the previous mouthwash I was using either. I don't get the squeaky clean feeling that I had come to expect.
I guess it's better than nothing and if you can stand the strong artificial sweetener aftertaste then the reasonable price makes it a great option for those on a budget. I highly doubt I will repurchase though.
The lasting impression of Colgate Plax mouth rinse is that it burns my mouth to the point of being unbearable. I really do like the clean fresh feeling it gives me but its hard to get past the burning feeling on my tongue. I like the flavour range it comes in and the fact that they leave my breath fresh which is gives great confidence. I team this with brushing and flossing and find that my teeth have strengthened up over the past few months and aren't as sensitive as they once were.
Tips: I use this first then brush to help get the burning out of my mouth faster.
