My skin is sensitive and both sides of this product, which are rough, irritate it more than they clean it. I will prefer a smooth surface next time.

My goodness, what is this thing that my tongue produces????

Pro tip: If you try to push your tongue too far back, you will start vomiting.

I use it after brushing. I saw a huge difference from the first time I used it! You feel freshness and coolness in your mouth and it has helped with bad breath.

I bought this product and I was amazed with the result, it is of very good quality and leaves a very good result, the tongue is very clean after using this tongue cleaner, highly recommended to buy it.
All you need is gentle movements from inside to outside and passing through the tongue three times first from left, middle, and right, not brushing with the bristles, we clean the surface where the mucus is with water and do the same as many times as we want. We do not brush the tongue because whatever bacteria, germs it has, we transfer them everywhere, just a light pull outwards and we have a fresh breath all day.
Also a tip:
First flossing
Second brushing teeth
Third tongue cleaning

It makes a big difference, I had a slight bad breath issue without knowing where it came from, and I had tried everything until I said let's try this too. It removes A LOT from the tongue... It is impressive in the first few days. Then it only takes half a minute every day, no need for more. Also, because it is thin, it is much easier to use on the back of the tongue, unlike a toothbrush that triggers the gag reflex just at the thought of it.

Wonderful product, from the first application I stopped having issues with my breathing. Definitely recommended for anyone who has breathing problems
