I am wondering if there is any history of teeth sensitivity with this treatment. All the teeth whitening things I've tried from the store hurt!

Hi Nancy, sorry for the delay. That would vary by the person. Since there is a limited time remaining, I'd suggest giving the business a call directly at (630) 357-9393. They'd be happy to answer your question in more detail.
