Review on Beaueli Whitening Carbamide Sensitive Sensitivity by Jackie Harbour

I recommend this product if you have sensitive teeth. I am a 30 year old woman. I have very weak teeth and my gums swell well. However, due to yellow teeth, it is necessary to use a teeth whitening pen. The gums were brittle and sensitive, so I was concerned that the whitening pen would not cause any side effects. When I used the whitening pen, I didn't have much pain in my teeth. After using the whitening pen, it became easier and faster for me to apply it to dry teeth. In fact, my teeth are weak enough that I feel pain in my teeth when I brush my teeth. Even for people like me, this whitening pen seems painless to an extent. Maybe I'll buy it again next time. The price is good and there are no problems with sensitive teeth.
