Expensive but maintains whitening. If you haven't had whitening done by a dentist, don't expect miracles with just a toothpaste

I bought it because my teeth had yellowed from coffee and cigarettes. With regular toothpastes, I was just maintaining oral hygiene. On the first day, I noticed a very small difference. After a week of using it morning and night, I noticed a whitening of my teeth by at least 4 to 5 shades. I also bought the toothbrush from the same company, which has many bristles that embrace the tooth without hurting the gums. Don't expect miracles from one day to another, it requires patience and depends on how damaged each person's teeth are. However, it definitely won't make your teeth as white as whitening.

From the effective whitening toothpastes. It was first bought by my sister who had intense stains from coffee and smoking, and for the first time I saw her teeth whiter than mine, even though I don't do either. I then bought it myself and I can really say that it offers whitening that lasts and achieves levels of whitening that you never thought you would have. At first, I used it intensively and when I reached an ideal level of whitening for me, I started using it every 2-4 days for maintenance. Very satisfied and I highly recommend it.
