Zoom In Office Bleaching

Patient Instructions Sensitivity Protocol


We recommend that your teeth be cleaned 2 weeks before bleaching.

We recommend using a desensitizing toothpaste with sodium fluoride (colgate total or sensodyne pronamel) two times per day for 10 -14 days prior to in office bleaching. Avoid any toothpaste that contains stannous fluoride.

We recommend 400 – 600 mg Ibuprofen 1 hour before the procedure unless contraindicated.

We recommend 15 – 30 minutes with Relief ACP gel in office before bleaching for very sensitive patients.

During the procedure

Your gum tissues will be protected from the bleaching gel.

Some areas of recession may be selectively protected to prevent them becoming more sensitive.

Relief gel maybe applied to the tongue side of your teeth to protect from sensitivity.

You will be able to communicate with us to let us know you are comfortable. If you are becoming sensitive we are able to turn down the intensity of the light and/ or discontinue the bleaching.


You will wear desensitizing trays for 30 minutes after the bleaching is completed.

You will continue to take 400 mg Ibuprofen every 6 hours for 1 -2 days as needed.

You should avoid eating or drinking for 2 hours following the procedure. Water can be consumed during this 2 hour period.
