OMG...I can still remember the PAIN today!
I purchased these swabs about 4 years ago. It was an experience for me. I just saw a commercial on POP TV channel and had to write a review! I don't have sensitive teeth but wow, after only the third day using these every tooth in my mouth ached so bad I couldn't eat for about 2 days. It was really awful & painful. I did notice a bit of whitening even after the first use and more after my third and final use. It was easy to use and the taste was really refreshing. But, please be careful because it took me several months for my teeth to stop having that awful nerve pain and sensitivity!
