This info on post operative info after teeth whitening or bleaching was created in our teeth whitening bleaching office.

It is common for teeth to be sensitive for a few days following office bleaching. Patients may describe this sensitivity as a momentary tingling or stinging sensation. This is a common post operative symptom that usually resolves within a few days. Refer to the section on Post Operative Instructions for Patients Following Dental Procedures regarding the use of pain medication if necessary.

Use a Fluoride mouthwash like Act or Fluorigard and Sensodyne toothpaste, several times a day for the week  following the bleaching. Avoid tobacco, coffee, tea and dark colored sodas and staining types of foods. If you must indulge, drink a glass of water immediately afterwards to minimize the staining effects.
