Sensitive teeth - no problem here!!
Thus far, my sensitive teeth have not been an issue with the whitening strips or pen! It’s great. I did have pretty white teeth to start, no too much stain, but still drank tea/coffee several times weekly & do enjoy a VERY bright smile, if possible. I work with patients & though I am always masked up, I enjoy being able to smile behind glass or face shield in office through a window, when possible. Even from a distance, outside. I want my smile to be memorable & put my best foot forward when possible. These products are gentle, yet effective. I have zero complaints.
