Review on 🦷 Professional Teeth Whitening Strips - USA Formulated for Sensitive Teeth - 24 Pack Dental Strip Kit - Remove Coffee, Tea, Smoking & Wine Stains - Fast, Safe & Effective by Donald Shah

I used these strips for 30 minutes as directed. Since 30 minutes is quite a long time, it's very difficult not to salivate during that time. The chemicals may have gotten down my throat, although I tried very carefully not to let that happen. All last week I have not slept all night with the feeling that the esophagus and throat are burned with acid, my eyes are also burning from the inside. There is no way of knowing if these chemicals aren't very dangerous to the body or if safety tests have been conducted. With that in mind, I would not use this product again and I would not recommend it. Just looking at the look of the product/packaging makes it look like something cheap made in China.
