I'm the one who likes to drink coffee and tea for a long time. After braces, my doctor commented on teeth turning yellow and advised me to find a toothpaste that helps clean the stain. So I started to find out about the substances that make my teeth became yellow. After researching coffee and tea have been found to contain chromogen, which is a color-causing substance, these substances are found in soft drinks and alcoholic beverages too. Including, acidic substances such as tannins corrode the enamel, causing the pigment to adhere to the tooth surface. So I started looking for a product that removes stains from tea and coffee until I met Zact Lion. After trying this product for half a year, in my opinion, this product makes my teeth less yellow, even after drinking tea and coffee as before. It removes stains excellently but does not whiten the teeth. For me, the breath smells fragrant and fresh, but the smell of the scented toothpaste is less than the toothpaste I have ever used. From my experience, It removes stains effectively. And it does not affect the health of my gums or teeth. It makes me more confident when smiling. They are also inexpensive and can be purchased in-store or online. However, I would urge you to consult a doctor after using it for a while. To see what the results are because each person's dental health is different. Hope my experience will be useful to you who are deciding to buy this product, good luck!.

That is good and effective after a week when i use it, although it is not particularly effective, but it has been slightly improved.It also not really expensive,suitable for long-term use.Especially those who love drink tea and coffee.
